Fire Behavior Analyst Jonathan Pangburn reports: “Well, as you can see outside, it’s been raining a little bit today and you heard from our meteorologist, we can expect quite a bit more of that in the near future. However, I do want to remind you that we just heard from our operations section chief Dave that they were able to do some firefighting out here, including some firing operations. And so I just wanted to remind our folks out there, when it’s raining and you’re still able to do a firing operation, it just goes to show how critically dry the fuels have been in this area. We experienced record breaking heat and we had record breaking dry fuels. So that is the challenge facing our firefighters. The rain of course, is going to keep the fire relatively in place. Where it is, we’re not expecting any rapid growth, in fact, we’re not expecting any real growth of the perimeter at all right now. However, our firefighters still have a challenging job in some very rough terrain to make sure that we get really extensive mop up and extinguish those heats so that when that temperature does rise and the heat air starts to dry, as you heard from Eric, that is going to occur starting in this weekend that we have a safe area that is not going to extend any further.”

With the significant increase in containment and tireless work by firefighters and cooperators to ensure that communities would be safe for repopulation, a large number of Mosquito Fire evacuees were allowed back home today. Both the Placer and El Dorado County Sheriff Offices downgraded many of the Evacuation Orders and Warnings in their perspective counties this afternoon.

Rain showers covered most of the fire area throughout the day. The cooler temperatures, higher humidity, and wet conditions subdued fire activity around the fire. Firefighters took advantage of these slower fire conditions to construct direct control lines along portions of the fire’s edge on the eastern flank. Firefighters with hand tools and heavy equipment, such as dozers, were out in force constructing these control lines. Crews worked in the area of the North Fork of the Middle Fork of the American River as well as the Interbay Road. Despite the rain showers, crews were able to successfully conduct firing operations along the Interbay Road and connecting control lines due to the sustained dry fuel moisture in the vegetation. Firefighters were able to continue strengthening and holding control lines around the southeast corner near Stumpy Meadows.

A majority of the aircraft assigned to the incident was able to be used throughout the day. Aircraft primarily focused on assisting the ground crews on the eastern flank of the fire. Helicopters were actively engaged in both water and retardant dropping missions. These air operations are a great resource for ground crews to knock down hot spots and reinforce control lines with retardant to the stop the fire’s progression.

Heavier rains and continued southwest winds are forecasted overnight and into Monday. A possibility of scattered thunderstorms may occur Tuesday. Firefighters will continue direct and indirect line construction along the eastern flank of the fire. Crews will patrol and mop up all existing containment lines along the southern and western flanks to ensure there are no threats to life and property in those communities.

Colder temperatures, good humidity recovery, and precipitation arrived overnight with the forecasted storm system. Rain showers are expected to continue throughout the day and become heavier this evening and into Monday. Southwest winds are predicted to become stronger midday with 24-28 mph gusts over the ridges. Higher humidity and temperatures in the 50s are expected for the fire area today.

Firefighters worked throughout the night to patrol, hold, and improve existing containment lines around the fire’s perimeter, especially along the impacted communities on the south and western flanks. On the north end of the fire, crews continued to monitor and hold the control lines on Deadwood Road as there had been increased pockets of heat below those lines on Friday. Firefighters continued suppressing fire activity and secured the slop over along the eastern front between the Middle Fork of the American River and French Meadows Road. Crews successfully continued firing operations overnight along the Interbay Road until precipitation arrived early this morning. These operations continue to aid firefighters in stopping the fire’s spread eastward. Day shift firefighters will work to tie in control lines coming down from the Eleven Pines Road through Devil’s Peak to the rim of the Rubicon River. Control lines consisting of dozer and hand lines connect the dots around the southeast corner back to Stumpy Meadows and Wentworth Springs Road.

As rain showers are forecasted to continue through the day and become heavier overnight, crews will look for opportunities to make containment progress as it is safe to do so. Firefighters will continue shoring up the corners of the fire and ensure the southern and western flanks hold along the communities.

Firefighters will also continue the process of backhauling unneeded hose, tools, and equipment from areas where they are no longer needed. Each day, operations section chiefs, law enforcement officials, and cooperators continue reevaluating the evacuation status of communities as they work towards safely repopulating these areas.

September 18, 2022 at 7:03 AM

Fire behavior Saturday night was minimal, consisting primarily of creeping and smoldering. Light precipitation occurred across the fire area Saturday night.

Saturday evening, southwest winds ahead of the approaching storm system were gusty over ridges. After 7 PM, winds diminished shifted to the southeast on ridges and light downcanyon. An inversion developed around midnight, blanketing the fire with heavy smoke. Temperatures dropped to 40–50 degrees with relative humidity rising to 75–90%. Light rain showers passed through in the early morning hours Sunday.

As the storm system moves inland Sunday, southwest winds will increase in the afternoon and early evening, gusting up to 28 mph over ridges. Temperatures will trend cooler and humidity higher. Wetting rain expected late afternoon Saturday, continuing into Monday. Tuesday could also see isolated thunderstorms, with lingering showers through Wednesday. More than an inch of rain is expected. Drier and warmer weather returns Thursday.

September 17, 2022 at 9:36 PM

As anticipated, increased southwest winds arrived today ahead of the approaching storm system with gusts of 20-25 mph along the ridgelines. Increased cloud cover and cooler afternoon temperatures moderated some of the fire activity today. Portions along the eastern flank of the Mosquito Fire remained active this afternoon as the fire continues burning in areas with dry fuels. A spot fire occurred just outside the fire’s main eastern edge in the area of French Meadows Road and crews are actively working to contain it. This spot fire is still within contingency lines that have been constructed on the eastern side of the fire. Firefighters continue to make good progress holding the fire along the Eleven Pines Road and other control lines along the eastern flank moving south towards the Rubicon River drainage. Crews were able to successfully engage in strategic firing operations to continue building a buffer along these control lines. Firefighters have been continuing to patrol the southern and western flanks of the fire to aggressively mop up any remaining hot spots anywhere near control lines. These crews are ensuring that the burned areas along containment lines are completely extinguished with no threat of escape.

Tonight, firefighters will patrol, mop up, and secure all established control and containment lines in an effort to ensure the fire remains within these existing lines while being tested by this wind event. Crews continue to monitor and hold portions of active fire along Deadwood Road and the eastern flank. Night flying helicopters will assist ground crews tonight with reconnaissance and water-dropping missions. Winds are forecasted to diminish overnight, with precipitation starting tomorrow and becoming heavier into Sunday night. The wetting rain is predicted to continue through Wednesday with totals forecasted to be close to 1” by the storm’s end. Firefighters are looking at this wet weather as a speed bump for the fire growth, where they can take advantage of the decreased fire activity and make good progress in increasing containment.

Placer County Sheriff announces repopulation of Zone 12: Foresthill Rd from Foresthill Bridge to Drivers Flat, Old Foresthill Rd/Old Auburn Foresthill Rd from Hwy 49 to Foresthill Rd, all roads off of Foresthill Rd within this stretch.

Fire behavior Saturday was moderate, consisting primarily of creeping, uphill runs, and isolated torching. Better ventilation cleared the thick smoke layer today. Fire areas exposed to the wind saw an increase in fire behavior. Fuel moistures lowered quickly in response to the air movement and sun exposure. Moderate humidity and cooler temperatures did not impede fuels from burning well in terrain with alignment to the wind. The fire made uphill runs in the North Fork of the Middle Fork of the American river. Isolated torching occurred in a few locations on the eastern portion of the fire. Surface vegetation experienced creeping fire.

Fire activity is expected to be minimal overnight Saturday. However, windy conditions will continue through the night and will keep vegetation ready to burn until the arrival of possible showers early Sunday morning.

Current situation on the fire here today. Starting down in the Middle Fort and coming up towards Todd Valley before his Hill area. It was real smoky in the morning. Got crews down in there, started mopping up along the fires edge and working in and I was asked to explain what mopping up is and just the short answer would be that’s like we asked you to do with your campfires, get in there, drown it, stir it, feel it, make sure that it’s cold and it’s out. And so they’re doing that for miles up out of this area down here and they’re doing it about 100ft in right now and working on getting even further than that. That mop up continued all the way up towards the Forest Hill Road and then out all the way through Forest Hill, out towards Michigan Bluff and out to the Deadwood Road and driving that road looks really good. There’s not a lot of smoke showing and when that smoke started blowing out with the winds this afternoon you weren’t even seen any new smokes down here low. So looking really good all the way across here coming up into the northern end of the fire. We keep working on our plan and our indirect fire line out to the east and bringing it down to the south. Did have a pocket of heat. Start putting up a lot of smoke in the afternoon around two or three in the afternoon. Didn’t move much, didn’t burn out much. Just looked impressive from a distance. At the same time as we were working on these outside lines we had folks in close to the fire working with dozers and with hand crews trying to get that thing down into the middle fork of the river and then on the south side of the middle fork of the river. I’m really glad to say today, even with those winds and even with the fire behavior, a bunch of crews were able to get down in there and start coming up from the river to the south. Gotten a really good firefight down in there holding the line where they couldn’t use dozers. They just pulled out the hand tools and the chainsaws and they just started working their way to the east along the fire’s edge for a few miles until they could tie that into French Meadows Road and then continue coming south and tie that in with those hand tools and going direct all the way over to eleven piles down in this area and then that road that they’ve been in a firefight the last couple of days holding onto it. They kept holding on to that and they were able to turn a corner off of that and start coming south. There’s a little pocket where they couldn’t get in close to the fire. But as soon as they could they took that opportunity. Come back out to that fire’s edge and keep working that with their hand tools. With their chainsaws. With dozers whatever tools they could use to get in there and corral this fire all the way down to the rim of the Rubicon River where they just couldn’t get in any further safely. Didn’t want to get anybody hurt. Just an amazing piece of firefighter all through this southeast corner of the fire today and we’ll see as they mop that up and as the wind continues to press, that how things go. But right now looking really good in there. Once you come across the Rubicon and you come down in that Stumpy Meadows area that’s kind of been like it has been for the last several days, they’re mopping up along the road systems and their line coming across into Quintet out to Volcano Bell. Things are really quiet, looking really good and that line hasn’t moved in several days now, so looking really confident in there and then when you start coming out Volcanoville towards Buckeye Point where did the firing operation five, six days ago now continuing to mop up and secure that edge and like I was saying was looking down in there this afternoon, it was looking really good. Thank you for listening.

September 17, 2022 at 8:06 AM

Overnight, firefighters continued patrolling and securing control lines in anticipation of increased gusty winds coming into the fire area today ahead of the advancing storm system. Winds are forecasted to peak midafternoon with 20-25 mph gusts along the ridges. These winds will test containment lines and have the potential to spread embers and start spot fires ahead of the eastern flank.

With the moderated fire behavior on Friday and last night due to the smoke inversion, crews and equipment continued constructing direct and indirect control lines to the north and east of the Mosquito Fire. Firefighters face challenging terrain in the North and Middle Forks of the American River to the east of the oncoming fire front. Crews have been successful in their operations to cut off the west and north corners, with the southeast corner fire growth slowing on its own as it burns into the King Fire scar. The burn operation in Middle Fork drainage below Todd Valley has been completed, and crews will continue to monitor and hold their control lines.

The weather changes will be the biggest challenge for firefighters over the next several days. Increased gusty southwest winds will arrive Saturday, with the main weather front and the first round of precipitation forecasted to begin early Sunday. Rainfall is predicted to last through Wednesday, with wetting rain totals nearing 1” by the end of the system. While the rain will help moderate and slow the fire’s growth, it is not forecasted to be a season-ending event. With the critically dry fuels and warmer weather back in the forecast for later next week, firefighters will use this weather system as an opportunity to make significant progress in containing the fire.

September 17, 2022 at 7:12 AM

Projected incident activity: On Saturday, the incoming weather system will bring wind gusts that could spread fire and produce spotting, especially along the ridgelines. Most of the fire will be subdued, though, due to the cooler temperatures and higher humidity.

September 17, 2022 at 6:55 AM

Today’s operations map for the fire. 71,292 acres and 21% contained. 78 structures destroyed, 13 structures damaged as a result of the fire across both counties.

Friday night was cloudless, but heavy smoke did cover the fire area. In the evening, light ridgetop winds were southwest, switching to southeast overnight (2–5 mph). Downcanyon winds were also light (4–7 mph). An inversion developed around midnight; temperatures were cool (around 50 degrees) and humidity recovery was moderate (60–70%). Smoke settled into drainages below the inversion.

Saturday, winds will increase ahead of a cold storm system, gusting up to 25 mph over ridges in the afternoon and early evening. Temperatures will trend cooler and humidity slightly higher. From Sunday into early Wednesday, rain showers are expected, bringing from 0.25–1.0 inches of precipitation. Drier and warmer weather returns Thursday.

Cooler temperatures and higher humidity under the smoke layer kept fire behavior substantially lower today. A thick layer of smoke remained over most of the fire area. In eastern areas where the smoke inversion did clear this afternoon, isolated areas of torching and burning occurred. The fire continues to steadily grow on its eastern front primarily near Ramsey Crossing and in the Middle Fork of the American River drainage due to the extremely dry fuels.

Firefighters completed the strategic firing operations along control lines below the community of Todd Valley, securing the fire’s edge into the American River. A small amount of remaining vegetation is slowly burning in the interior of this area. These operations have helped secure the southwest corner of the fire and firefighters will continue to monitor and hold these control lines. Crews continued similar holding operations on the north corner of the fire along Deadwood Road, while crews and heavy equipment took advantage of the moderated fire activity and started constructing direct control lines along portions of the fire’s eastern flank. Great progress continues holding the fire along the Eleven Pines Road. There was no new growth on the southeast corner where the fire has bumped up against the King Fire burn scar.

With the forecast of strong winds coming into the area tomorrow ahead of the incoming weather system, firefighters are completing the critical mission of patrolling and mopping up all hot spots while eliminating any issues that may cause the fire to jump containment lines. In anticipation of the weather, the U.S. Forest Service has responded with two night flying helicopters to assist with reconnaissance and water-dropping capabilities.

September 16, 2022 at 7:31 PM

Matt Jedra, Acting Tahoe National Forest Supervisor: Currently the Placer Grove Big Trees is about three to 4 miles from the edge of the fire. This is the northernmost grove of giant sequoias we have in California. We’ve done a tremendous amount of work over the past couple of days to get this area prepped. We’re looking at doing some prescribed fire through this and doing some raking and some thinning around there. So if fire were to come through there at some point, the trees would be protected at that point and also provide a good defense. Like I said, a lot of resources in there over the past couple of days, and they’re going to be in there until we end up getting this fire front, should it come to that point, to have those trees protected.

Fire behavior Thursday night was moderate. South of Foresthill, crews had a very productive night as they conducted a successful firing operation to secure the southwest side of the fire. In the Chicken Hawk area, they extinguished hotspots along the fireline. Night Operations Chief Don Fregulia reported seeing “no glows” when he patrolled the area early Friday morning. The fireline along the Deadwood Road is also holding nicely. He complimented day-shift firefighters at this morning’s crew briefing: “The direct-suppression work at the head of the fire is evident at night, and we’re very appreciative. You have made up a ton of ground on the east side. While not all the dots connect up just yet, there’s excellent work going on, and it’s really slowing down the progression of the fire to the north and the east.” From the southeast corner westward along the entire southern side, crews patrolled and mopped up hotspots as they encountered them.

Forecast models show the potential for an AR 1 (based on the Ralph et al. 2019 AR Scale) in the foothills of Northern CA near the location of the Mosquito Fire, but there is still uncertainty in the magnitude and duration of AR conditions

GFS and ECMWF ensemble forecasts are showing mean areal precipitation (MAP) over the North Fork American watershed around 1 inch over the next 10 days with considerable spread among individual ensemble members

Placer County Health and Human Services and the Placer County Air Pollution Control District have extended the joint air quality advisory through Monday, September 19, 2022, to notify the public of continued poor air quality conditions from smoke from the Mosquito Fire burning in both Placer and El Dorado counties. On Sunday and in the coming days, rain is expected to reduce — but not entirely eliminate — smoke, depending on fire activity.

El Departamento de Salud y Servicios Humanos del Condado de Placer y el Distrito de Control de la Contaminación del Aire del Condado de Placer han extendido el aviso conjunto sobre la calidad del aire hasta el lunes, 19 de septiembre de 2022, para avisar al público sobre las condiciones deficientes del aire debido al humo causado por el incendio Mosquito quemando en los condados de Placer y El Dorado. Se anticipa lluvia en los días que vienen cual reducirá – pero no eliminará – el humo, dependiendo en el nivel de actividad del incendio.

September 16, 2022 at 7:38 AM

Firefighters continued to hold the Mosquito Fire within existing control lines along its western and southern flanks. The aggressive work of firefighters has minimized damage and further spread into affected communities along the fire’s edge. With the threat of stronger winds in the coming days due to an incoming cold front, crews will relentlessly patrol the fire’s perimeter for heat, smoke, and any potential issues that could cause the fire to jump containment lines. On September 13th, firefighters and the public saw firsthand how quickly a spot fire could jump control lines and threaten the communities again with little to no time to escape.

On Thursday, the fire’s eastern flank remained active with steady growth towards the Ramsey Crossing area. There, crews are using defensive firing operations along the Eleven Pines Road and control lines running south through Devil’s Peak to stop the fire’s growth towards McCulloh. Firefighters have continued work to hook the fire around the southeast corner by constructing control lines and using strategic firing operations when possible in the Stumpy Meadows area. Crews plan to utilize the Wentworth Springs Road as well as hand and dozer lines moving north across the Rubicon River drainage. With increased smoke shading on the northern portion of the fire, firefighters have made progress in holding their control lines along Deadwood Road.

The persistent southwest winds will continue and become even stronger as the approaching cold front arrives this weekend. Cooler temperatures, higher humidity, and wetting rains are forecasted for Sunday and lasting into early next week. Firefighters will welcome precipitation, but the stronger winds have the potential to cast embers farther out in front of the fire. Crews will continue the difficult work of constructing primary and contingency lines ahead of the north and eastern portions of the fire. With multiple steep and rugged river drainages to navigate, creating contingency lines will provide firefighters and communities with a secondary safety net should the fire jump primary control lines.

People Evacuated: 11,277
Structures Threatened: 9,236
Total Structures Destroyed: 73
Total Structures Damaged: 13

Total Personnel: 3,873

Today, southwest winds continue but decrease in intensity from 4 to 7 mph with gusts to 13 mph. Temperatures and humidity levels remain similar to previous days. A cold system will bring increased southwest winds on Saturday, gusting up to 25 mph over ridges. Temperatures will trend cooler and humidity higher. There is a chance of rain showers starting Sunday into mid-week, with wetting rain expected. Over 0.25″ total is possible.

Weak ridging Friday will lead to a bit more air stability, warming of surface temperatures a few degrees, and a little drying. Heavy smoke will continue to influence fire behavior. Areas shaded by smoke will stay cooler and dampen fire activity. Fire behavior today is expected to be similar to Thursday’s.

Fire Behavior Analyst (FBAN) report during the virtual briefing:

In advance of an upcoming trough or slightly colder and wetter system coming in, we’re going to have some stronger winds. Tomorrow is a little bit similar to today. And then starting Saturday we’re going to have a stronger wind system but increased humidity and lower temperatures. It’s going to get much colder as the system comes in from the Gulf of Alaska and comes down into continental United States and really changes the system for us here. Somewhere around Saturday night to Sunday morning, we should be seeing some precipitation, some measurable wedding rains through Tuesday, possibly into Wednesday period, there’s about an 80% chance of at least a quarter inch. And at this point the weather service is forecasting about a 50% chance of possibly greater than an inch of rain. But that is of course, over multiple days. So it’s a little bit of showers here and then a break and a little bit of showers again. So it’s not all one large rain event. And that’s a bit of a mixed blessing here.

The increased winds are certainly not going to be favorable. That is going to continue to have the possibility to throw more embers in front of this fire and create spot fires, which would not be helpful. But on the other hand, of course, the moisture is a welcome relief for all of us in drought stricken California.

So how does that affect fire behavior? Well. First and foremost before that system comes. This area in the northeast, so kind of the Deadwood and Chicken Hawk and out Foresthill Road into the Northeast. We’re seeing a lot of smoke impacts where the wind is pushing the smoke over another part of the fire and it’s starting to settle that down. Which is helping the firefighters with some more of their mop up activity for those lines you heard discussed that are going to be really important for taking any seam out of it if it tries to make a run past Foresthill Road.

The smoke is coming from this area down here though in the Ramsey Crossing down to Devil’s Peak and not quite the Stumpy Meadows, but really more of this Devil’s Peak/Ramsey Crossing area that right there is creating the greatest amount of growth on the fire.

If you’re looking especially from down the hill and you see some plumes of smoke start to rise above the general rest of the haze that’s generally these areas right here developing the most. It’s growing about maybe half mile a day and it’s starting to chunk in front of itself.

I just want to address something that I mentioned before. The fuels are very dry. As you know, we’ve been in the drought and we had a record heat wave and so the cooler temperatures and the lighter winds are certainly helpful for not spreading the fire as fast as it had been traveling. But the difficulty of control out in the heavier fuel loading in this particular area is going to continue to create a challenge. And that’s why you just heard the plan for not only one line coming down here, but multiple redundancies and secondary contingencies to make sure that we have a good opportunity to stop the fire.

And then, of course, I want to address the primary concern in communities from Quintette, the Georgetown Divide, Volcano Area, Volcanoville, Foresthill, Todd Valley, all of those no movement expected. The piece that is still being burned in here next to Todd Valley estate is going very, very well. That’s been backing down the hill and has been quite a successful operation to this point.

September 15, 2022 at 6:54 PM

The official evening update:

Firefighters focused on securing the west corner of the fire down in the Middle Fork of the American River below the communities of Todd Valley and Foresthill. Crews are finishing the last remaining portions of firing operations along the control lines that tie into the river. Unmanned Aerial Systems (UAS) are assisting ground resources with aerial ignitions to strategically burn remaining vegetation inside control lines to secure.

Firefighters are working diligently along the western edge of the fire along the Foresthill Road corridor to mop up and secure all control lines to mitigate any threats of slop overs. On the north corner of the fire, crews worked throughout the day to hold and secure the control lines along the Foresthill Divide the Deadwood Roads where strategic firing operations took place last night. These actions are crucial in holding the fire south of Westville. Critically dry fuels continue to fuel the Mosquito Fire’s steady growth to the east. Crews, dozers, and heavy equipment continue the dangerous and grueling task of building indirect control lines in steep and rugged terrain. Crews are also utilizing existing roads systems, such as the Eleven Pines Road, to assist in building a solid control line to hold advancing fire. Crews are constructing a combination of dozer and hand lines from Wentworth Springs Road north towards Devil’s Peak in the effort of holding fire in the Rubicon River drainage. Firefighters continue to mop up remaining hot spots and patrol the southern edge of the fire along Volcanoville Road. Cooperators and utility companies continue work in these areas to assess and start needed infrastructure repair with the goal of repopulating the communities as soon as it becomes safe to do so.

An incoming weather system is forecasted to bring increased winds and precipitation into the fire area starting Saturday and into early next week. Firefighters will continue to strengthen and secure all control lines in preparation for these changing conditions.

September 15, 2022 at 6:22 PM

The fire was mapped at 67,668 acres at 4pm. Most active today in the Stumpy Meadows and the firing operations in the Westville area where Foresthill Road and Deadwood Road are joining.

September 15, 2022 at 7:35 AM

Today’s priorities remain securing each of the three corners of the fire. Firefighters have been very successful in holding the control lines along the communities of Todd Valley and Foresthill despite challenging fire conditions on Tuesday. Crews will continue extensive mop-up operations in those areas, the Foresthill Road corridor, and on the portions of line to the north of Volcanoville. Southwest winds have been favorable for the communities along Volcanoville Road, but firefighters remain in the areas to ensure the fire does not spot across containment lines. These mop-up operations include firefighters using hose lines, water, and hand tools to thoroughly extinguish or remove remaining burning material well inside the fire’s edge. This is to ensure that no smoldering debris will roll, fall, or fly over the containment lines and start a spot fire. With the critically dry fuels in the area, it only takes a small ember to start a spot fire and spread rapidly in the steep terrain.

September 15, 2022 at 7:35 AM

Overnight, smoke settled back into drainages due to easing winds, with a majority of the fire area seeing good humidity recovery. Firefighters continued working throughout the night, patrolling, mopping up, and securing control lines around the south and east sides of the fire. Crews and heavy equipment, including a large number of dozers, continued constructing indirect lines adjacent to steep and rugged terrain to the east of the main firefront.

Firefighters remain engaged on the north side of the fire near Deadwood Road. Crews continued bringing strategic firing operations down the Deadwood Road from the Foresthill Divide Road with the intention of stopping the fire’s northern spread. Firefighters were conducting similar operations on the southeast corner of the fire near Stumpy Meadows by constructing control lines and utilizing firing operations to secure them.

September 15, 2022 at 6:51 AM

Weather forecast: Onshore flow continues today with lighter southwest ridge winds for the afternoon. Mostly sunny conditions and good ventilation will bring quite a lot of sun on the fuels, except for areas shaded by smoke. Temperatures will be cool again today and will be below normal for mid-September. Humidity values will trend higher with continued onshore flow, but these features will likely be offset by the increased sunshine, early inversion break and increased southwesterly ridgetop winds.

Outlook for Friday: Southwest ridgetop winds with gusts to 1 O mph. Temperatures will be seasonably cool in the 60s and lower 70s. Afternoon humidity 28-45% with moderate night time recovery to around 60%.

Cooler weather is expected Saturday, with highs in the 60s and increasing southwest ridge winds gusting to 20 mph. Periods of rain showers are possible late Saturday night into early next week and could potentially bring wetting rain.

Fire behavior separated by two distinct zones:
Clear air: group torching and upslope/ridgeline runs; smolder under smoke.

Air operations: Clear air in the south; smoke impacts in the north.

Operations update from the briefing: “I’d like to start down here in the Quintet area. We’ve had really good success with our containment line, getting in there, mopping them up, getting in there, really feeling stirring and drowning and putting out that fire all along here, coming out to Volcanoville, along the Volcanoville Road and then out and down into the Middle Fork of the American River. When we start getting down into this area of the Middle Fork, there’s still a lot of work to be done down in that river canyon, getting in there, reinforcing that line, mopping that up and really making sure that fire is controlled. And then coming up out of the Middle Fork towards Forest Hill and then out the Forest Hill Road to the east and out towards Michigan Bluff Road, same thing. Getting in there, making sure that this fire is really out and that this containment line is going to hold. And that’s a high priority for us because that’s how we’re going to be able to give our thumbs up and say it’s safe to the sheriffs that we’re working with for you to get back in there. And so we’re daily working with those sheriffs, coordinating what’s going on on the ground so that we can work towards that end. When you start getting out past Michigan Bluff Road in the Chicken Hawk Ridge area in the seed orchard, we’re still working with an active fire edge across the entire eastern edge of the fire. What we’re doing out here is a combination of efforts where we’re using what’s called a tactical firing operation and we’re putting fire down to create a wider fire break then we could just with Dozers or with a hand crew. So if the fire strikes coming out of these creeks or the river drainage down there has something to run into, loose and see and not cross the road. Where we’re really working out right now is where we’re going to be coming around out by Robinson Flat and down south towards French Meadows Reservoir, getting that prepared, giving ourselves plenty of time to be successful in keeping this fire as small as possible. When you come down from French Meadows, one of the biggest obstacles we’ve got is the North Fork of the Middle Fork of the American River. Steep, rocky, nasty terrain. It’s just not safe to put people in and we just don’t have the time with the fire spread to really get in there safely and effectively and get that done. Right now we’re looking at opportunities in the American Hill area to tighten that up. But when you get right down to it, right now we’re having to look out here, coming down into here, we start getting into the Middle Fork of the American River and being able to bring that down on the south side of the river in here. We’ve been coordinating with SPI we’ve got a lot of firefighters out there finding ways to start bringing this fire line together. Having a really good plan, bringing it down towards the Rubicon River and done some really good work down here in the Rubicon. Found a very improbable place where we’re anticipating this success. Several miles further to the west than we initially anticipated in getting across that river with our line and expecting it to hold and then tying that into wet worth brings road into something better. Thank you.”

Out of the area resources

September 14, 2022 at 6:56 PM

The virtual evening briefing will start at 7:00 pm.

Firefighters continue to hold the Mosquito Fire inside established control lines with the help of cooler temperatures and higher humidity. Throughout the day, crews continued to patrol, mop up and secure control lines along the Foresthill Road corridor, with a heavy focus on the area where yesterday’s spot fire made an aggressive run towards the community. Aerial reconnaissance shows very little smoke production in the areas below the communities of Foresthill and Michigan Bluff. Successful firing operations continue to take place along Deadwood Road to cut off the fire’s growth to the north.

The Mosquito Fire’s eastern front continues to steadily grow with active fire behavior into dense forested areas with critically dry fuels and little fire history. A majority of the fire’s smoke column today was produced by the fire activity in the Middle Fork of the American River on the east side. Dozers and heavy equipment worked throughout the day to continue expanding control lines to stop the fire’s eastwardly growth. On the southeast corner of the fire near Stumpy Meadows, crews constructed control lines in an effort to cut off the fire in the Rubicon River drainage. The southern portion of the fire continues to hold with firefighters constantly patrolling all portions of these control lines and mopping up hot spots well into the interior of the fire perimeter to ensure there is no threat of escape.

Today’s southwesterly winds were lighter than Tuesday, but still provided the needed air mixing to push the smoke inversion out of the fire area. With this clearer air, aircraft assigned to the incident were able to be used heavily for various operations around the fire. Helicopters have been busy throughout the day conducting water and retardant dropping missions in order to assist ground crews in extinguishing hot spots and preventing fire growth. Multiple mobile retardant bases are located around the fire to assist helicopters with quick refilling of fire retardant. Multiple Unmanned Aerial Systems (UAS) are being used to assist with reconnaissance, mapping, and infrared capabilities to assist firefighters in locating hot spots near the fire’s edge.

September 14, 2022 at 9:15 AM

Air Attack is over the fire and reports everything looks good on Foresthill Road, nothing on the north side of the road. Firefighters are stretched out along Todd Valley and mopping up, doing great work on that line.

September 14, 2022 at 8:55 AM

Overnight, firefighters successfully held the fire within control lines along the southern edge of Foresthill and Todd Valley. On the northwest corner, crews were able to continue strategic firing operations along control lines from the Foresthill Divide Road to Deadwood Road. This four-mile stretch of line is crucial for helping hook and stop the fire’s northern spread. A large number of dozers and heavy equipment continued to work through the night in the areas to the east of the fire to build indirect control lines ahead of the advancing fire front. The fire remains active on this eastern front, steadily burning and advancing in heavy unburned fuels.

Today’s number one priority remains strengthening and securing the southwest corner of the fire to protect and defend the communities of Foresthill and Todd Valley. Firefighters are prepared to actively engage in structure defense along the edges of these communities should the fire make similar runs as it did on Tuesday. Weather conditions are forecasted to be the same today with continued southwest winds, which will lead to clear skies and better ventilation for fire growth.

September 14, 2022 at 7:39 AM

The fire was active Tuesday night into Wednesday morning, particularly on the northeast side. Night-shift crews completed firing operations on the north side from Forks House Trailhead to the Deadwood Road. On the west side, south of Foresthill where the fire spotted over the Middle Fork of the American River Tuesday afternoon, fire activity did moderate overnight. The mission-critical priority for firefighters Wednesday is the west side of the fire; they will focus on protecting structures in the Foresthill and Todd Valley areas and increasing containment of the fireline to prevent further westward and northward spread. The southeast corner is also a priority as crews strive to halt the fire’s progression toward Stumpy Meadows. Numerous aircraft are supporting ground crews, conducting water and retardant drops during both day and night shifts.

Containment has decreased to 20%. Fire behavior Tuesday night was active, consisting of backing, uphill runs, and group-tree torching. The fire remained active throughout the night into Wednesday morning. Conditions facilitated the firing operations that necessary to secure several miles of containment line.

September 14, 2022 at 6:39 AM

Updated perimeter might be coming soon, FIRIS is over the incident again.

A weak weather system will exit the area today bringing continued breezy southwest winds for the afternoon. This should break the inversion early and ventilate the fire after 1300 hours. Mostly sunny conditions and good ventilation will bring quite a lot of sun on the fuels. Temperatures will cool further today and will be below normal for mid-September. Humidity values will trend higher with continued onshore flow, but these features will likely be offset by the increased sunshine, early inversion break and increased southwesterly ridgetop winds.

Weather outlook for Thursday: A dry cold front on Wednesday will bring breezy Southwest ridgetop winds with gusts 20-25 mph possible. The stronger winds and cooling aloft should allow the inversion to break early with a longer afternoon burn period. Temperatures will be seasonably cool in the 70s and lower 80s. Afternoon humidity 25-35% with moderate night time recovery to around 60%.

September 14, 2022 at 5:10 AM

September 13, 2022 at 7:42 PM

Fire activity increased as anticipated Tuesday, particularly on the southeast side near Buckeye Point and the northeast and east sides. The fire remains south of Foresthill Road. However, the twists and turns of the American River near Buckeye Point channeled and swirled the winds in such a way that burning embers were caught up and carried in the wind across the river and ignited a spot fire. As of Tuesday evening, the incident management team has received NO reports of spot fires on the north side of Foresthill Road. Clear skies allowed aircraft to fly numerous missions today as they assisted ground crews in the firefight. 

Light downcanyon winds early into the evening may be problematic for the spot fire on the southwest side near Buckeye Point.

Smoke will settle into the drainages overnight Tuesday. Humidity recovery will be around 70% with low temperatures in the mid 50s to around 60. Southwest evening winds will turn light downcanyon overnight. On Wednesday, breezy southwest winds return in the afternoon with gusts to 15 to 20 mph. High temperatures should be about 5 degrees cooler, and humidity will trend up.

September 13, 2022 at 7:23 PM

Fire behavior analyst at the briefing: “We still have the winds out of the southwest pushing to the northeast. They’re not dramatically strong, but they’re strong enough to give clear air. What that means is that it’s going to continue to have potential for progression out in this northeastern portion of the area of the fire. As we move down on the southern end of the Middle Fork of the American River and out toward the Rubicon River, we’re really seeing the effects of that wind as well, pushing it away from Stumpy Meadows Reservoir. Thankfully, I know a lot of firefighters are in there trying to make sure to stop the southward expansion to more values at risk and the wind is helping with that in terms of the containment toward the south and helping to drive it into more of the forested area where they are again trying to turn the corner. And I want to finally touch on the communities to the south, Quintette, Volcanoville and past the Georgetown Divide and into Georgetown and beyond into El Dorado County. Two things are happening there. One, we have a lot of firefighting going on, trying to make sure to take the heat out of any of the fire that had been in this area southwestern portion of the fire. And two, the wind is thankfully in our favor, again, trying to push away from there. “

September 13, 2022 at 7:11 PM

Today’s slightly stronger southwest winds aloft broke up the smoke inversion that has been hanging over the Mosquito Fire for the past several days. With the smoke inversion clearing out by midday, the fire actively increased significantly this afternoon due to the increased ventilation and available oxygen to support burning.

This afternoon, a spot fire jumped the Middle Fork of the American River on the west corner of the fire’s perimeter in the Pond Creek Drainage. Due to the critically dry fuels, steep terrain, and increased ventilation, the spot fire grew rapidly towards the community of Foresthill. Firefighters and resources from around the fire have been diverted to assist with holding this corner of the fire at the contingency lines that have been put in place by crews over the past week below the community. Firefighters and a large aircraft contingency, including both fixed and rotor wing aircraft, have been engaging in active structure defense, defensive firing operations, and working to hold the advancing spot fire at control lines and protect the surrounding communities.

The fire also remained active on the north corner of the fire just north of Chicken Hawk Road. Crews continue to actively construct control lines and utilize strategic firing operations when possible in an effort to hook this corner and cut off its growth to the north. The Mosquito Fire continues to advance steadily to the east in heavily forested areas with extremely dry vegetation. Crews continue to construct indirect lines and utilize existing road systems ahead of the advancing fire to cut off the fire’s growth to the east. On the southeast corner of the fire, the fire’s edge continues to move towards Stumpy Meadows where firefighters are being challenged with difficult terrain and opportunities to stop the fire in the Rubicon River drainage.

Southwest winds and cooler temperatures continue to be forecasted for the next several days which should create similar weather conditions as seen on Tuesday, thus clearing the smoke inversion earlier in the day.

Placer County Health and Human Services and the Placer County Air Pollution Control District have extended the joint air quality advisory through Friday, September 16, 2022, to notify the public of continued poor air quality conditions from smoke from the Mosquito Fire in both Placer and El Dorado counties.

September 13, 2022 at 7:42 AM

Already relatively clear skies in Foresthill. In keeping with the projected incident activity, atmospheric mixing will continue to increase, allowing the fire to breathe. The extremely dry vegetation, stressed by the record-breaking September heat wave, will generate even more heat as it burns, which will lead to more mixing and air flow. Sunny skies will allow a smoke plume to develop as record-breaking dry large vegetation is consumed and the fire moves into remote, rugged terrain.

Firefighters working on the fire’s southwest side between Foresthill and Volcanoville, had a very successful day Monday. They completed an important firing operation from Buckeye Peak to the American River that had been shut down by high humidity and some precipitation the previous night. Fire was most active on the north and east sides. Aircraft were able to flight late Monday afternoon but were mostly hampered by poor visibility.

September 13, 2022 at 4:54 AM

The fire was mapped at 49,671 acres last night. Today’s day briefing map is below. There has been no change in the control objectives:

  • Keep the fire North of Wentworth Springs Road.
  • Keep the fire South of Foresthill Road.
  • Keep the fire East of Drivers Flat Road.
  • Keep the fire West of Eleven Pines.
Day briefing map for 0913

September 12, 2022 at 7:17 PM

Some notes from the briefing regarding fire behavior: There was a slight mixing of the air with a little bit of wind movement. Today we specifically had that persistent southwest flow that’s starting to push the fire deeper into the forested areas. But that’s good news for the communities such as the Forest Hill, Volcanoville and Quintet communities. Moving up into this northeastern portion of the fire. We observed fire coming up into the crowns of trees or torching in groups and it really started to move with some of the limited airflow that we have today, we’re expecting that airflow to increase a little bit tomorrow and especially into Wednesday. So we’re expecting a little bit of an uptick in fire behavior and I want to touch on that. We are seeing historically dry fuels.

The public ops briefing

YouTube video

September 12, 2022 at 8:38 AM

Projected incident activity:

12-hour time frame:

Increased transport winds and better mixing will allow ventilation, although cooler temperatures and higher relative humidity will lessen this impact. Still, increased fire behavior is anticipated, especially with the southwest flow driving the fire upslope and into canyons. Deadwood Ridge, Chicken Hawk Ridge, Ralston Ridge, Long Canyon, Middle Fork American River, and Rubicon River start to come into alignment for fire spread.

24-hour time frame:

Atmospheric mixing continues to increase, allowing the fire to breathe. The extremely dry vegetation, stressed by the record-breaking September heat wave, will generate even more heat as it burns, which will lead to more mixing and air flow. Sunny skies will allow a smoke plume to develop as record-breaking dry large vegetation is consumed and the fire moves into remote, rugged terrain.

September 12, 2022 at 7:52 AM

The Mosquito Fire continues to progress primarily to the north and east. Despite cooler temperatures, the historically dry fuel moisture in the vegetation continues driving the fire’s growth. On Sunday, the fire made a run to the northeast in the drainage between Foresthill Road and Deadwood Road. Firefighters have been building in-direct control lines and when necessary utilizing strategic firing operations to stay ahead of the fire on this corner.

Crews continue to look for opportunities to build in-direct control lines between the eastern front of the fire and Last Chance. The steep and rugged terrain make it difficult for ground crews to access the fire directly, therefore building control lines ahead of the approaching fire and building a buffer with defensive firing operations will allow firefighters the opportunity to slow and potentially stop the fire’s forward progress.

There was no significant growth on the southeast corner of the fire on Sunday, which gave crews more time to construct control lines coming out of Stumpy Meadows. Over the past few shifts, firefighters have been successful in securing containment lines on the southern edge along Volcano Road and to the north of Quintette. Crews continue to monitor these areas as well as strengthening the remaining control lines along this southern boundary to gain more containment.

Firefighters continue to work towards hooking the southwest corner near Buckeye Point. Crews have successfully built a control line consisting of dozer and hand lines to the Middle Fork of the American River. This control line, in combination with firing operations, will help firefighters secure this piece of the fire perimeter. Locking in this southwest corner of the fire is today’s top priority for firefighters. Crews are also in the area of Todd Valley working to build contingency lines to further protect the community of Foresthill.

September 12, 2022 at 6:34 AM

No significant change in acreage overnight. Today’s briefing map is below. A detailed ops map is here as a pdf file (10MB).

People Evacuated: 11,260
Structures Threatened: Approximately 5,848

As anticipated, fire activity and smoke production increased Sunday afternoon after the inversion lifted over much of the fire. However, thunderstorms remained south of US Highway 50 and did not affect the fire. Other conditions that often lead to active fire behavior, such as hot, dry, windy weather, have not been present recently nor are they expected to materialize this week. The incident’s fire behavior analyst cautions, however, that “while this is not a weather show, it is a fuels show.” All the vegetation—from fine grass to big trees—is extremely dry and burning readily. Incident Commander Rick Young went on a reconnaissance flight Sunday afternoon and confirmed that “the fire wasn’t going anywhere fast (i.e., not wind driven), but where it was burning, it was really burning.”

Pink Foresthill ROad
Foresthill Road

Helicopters flew water-dropping missions Sunday afternoon, providing assistance to firefighters on the ground, primarily on the western perimeter near Foresthill and the northern side near Deadwood Road where the fire was quite active along portions of the Western States Trail.

All around the fire’s perimeter, crews are using a combination of direct- and indirect-suppression tactics. As much as they are able, they are constructing fireline close to the fire and directly extinguishing the flames. Elsewhere, they are constructing handline and dozer line away from the fire’s edge and conducting firing operations to create a buffer and reduce the likelihood of the fire making out-of-control runs across the landscape. On the fire’s east side, for example, crews are removing trees and brush from firelines that were constructed during the American and King fires.

Firefighters will remain on the fireline throughout the night, protecting communities, extinguishing hotspots, patrolling, and conducting firing operations as weather conditions allow.

September 11, 2022 at 8:09 PM

IC Rick Young: “I want to assure you we are implementing a very aggressive full suppression strategy with the intent to get you back into your home quickly as possible. But it’s a process. There’s lots of things that need to occur. First, the fire needs to be lined, and with currently over 80 miles of fire perimeter, all of which needs to be lined, mopped up, patrolled by firefighters that are out there working 24 hours a day, it still takes a lot of time. So I ask you for your patience as we continue to work as diligently as we can to make that happen.”

September 11, 2022 at 7:35 PM

In the briefing just now, NEU Unit Chief Brian Estates has good news for Placer County: ” The forward progress of the fire in Placer County has been stopped to the west and we are securing that and we will maintain that security of that fire. The entirety of the fire line underneath Forest Hill from Baltimore Mine East to Baker Ranch has been secured.”

September 11, 2022 at 6:40 PM

Short evening update: 46,587 acres and 10% contained. Fire behavior remained active today. Evacuation Orders and Warnings remain in effect. Structures and multiple communities remain threatened.

September 11, 2022 at 8:30 AM

The message from the Incident Commander to the fire fighters this morning included this: “Thank you for the good work that’s going on out there. We’re able to get some black on the map and show some containment this morning and that’s going to go a long way in this community to bring some relief and that’s all reflection of the work you guys are doing out there. So thank you for those efforts. There’s still a lot of work left out there, so keep your heads up as we move forward, but we’re making progress. The community is going to appreciate that.”

September 11, 2022 at 7:48 AM

Some highlights from the ops briefing:

Night operations highlights: For Foresthill, they were able to get the fire all the way down to the American River last night. There’s a ton of work still to be done, but a good successful night on that Baltimore Mine Road coming across over to Buckeye. They kept up with the fire last night. The line is mostly all the way in, if not all the way in by this morning. As you come around through Volcanoville down into Quintette, that’s all looking good.

Day operations: Some special missions out in Division Juliet by the Big Trees. Lots of indirect line construction and prep work for potential firing operations. Mop up and holding the established lines.

Air operations: Seven Type 1, three Type 2 and two Type Helicopters. Helco and Air Attack full coverage for the day. A nighttime Helco for any intel gathering if that’s needed. Two Super Scoopers that came in yesterday, they are going to be based out of South Lake Tahoe and dipping in the reservoirs just on the east side of the fire support.

September 11, 2022 at 7:17 AM

No big weather changes are forecast for Sunday. Smoke and clouds will expected to shade the fire, resulting in somewhat reduced fire behavior. High temperatures will be generally in the 80s and minimum humidity 25-30%. Winds will generally be southwest 5-10 mph.

Operations map for 0911
Operations map for 0911

September 11, 2022 at 7:11 AM

Fire behavior Saturday was moderate, consisting of isolated torching, uphill runs, and short-range spotting. When air cleared, the fire exhibited isolated torching and slope runs, especially on the southwest side near Georgetown. Elsewhere around the perimeter, fire behavior was reduced under the smoke inversion. Critically dry vegetation is readily igniting and burning despite the improved weather. When rollouts occurred, the fire made upslope runs.

Saturday night, fire behavior moderated as humidity increased.

September 10, 2022 at 10:36 PM

Official evening update: Cooler temperatures and higher humidity assisted with moderating some fire activity on the Mosquito Fire today, however an increase in winds has continued the fire’s spread to the north and northeast. Firefighters have been working diligently to build control lines along the area of Foresthill Road and out in front of the head of the fire toward the north and northeast. A spot fire in the area of Chicken Hawk occurred yesterday and firefighters were able to contain that fire with the help of dozers and aircraft today.

Crews are opening up previously used control lines from past fires to assist in their efforts. Firefighters have been making good progress on the southern edge of the fire using dozer and handlines. A large amount of resources have been working to hold the fire at Volcano Road as well as north of Quintette.

With the increase in fire activity to the east of the communities of Foresthill, several more Evacuation Orders and Warnings have been issued. More resources from throughout California continue to arrive to assist in the suppression efforts. Both fixed-wing and rotor-wing aircraft continue to assist ground crews as flying conditions allow.

Some key points from the briefing:

Taken from Wortens at 8:10pm

Point of origin for the fire, started off down here in Oxbow. It’s currently under investigation. The start of the fire happened on September 7. The fire grew pretty rapidly into what it currently is now. Most of the fire’s edge is currently pretty active here. All the fire’s edge up here along the east side of the community of Foresthill remains pretty active as you kind of continue north around the northern part of the community here.

Crews are going direct with hand crews, dozers and engines to pick up the fire’s edge direct as much as possible where the terrain will allow them to do so. If they continue north they’re going to take an indirect action there just because of the terrain features.

They will have contingency lines that come out to the north here heading northbound, that will connect along Chicken Hawk Road heading northbound. The fire still remains pretty active here on the north end of the fire.

We did get some reprieve with some of the weather that we’ve had, but the fuels conditions are still pretty volatile at this time. As we continue north here, the fire east of Chicken Hawk Road remains very active. Crews are working that edge now going north to stay out in front of the main fire there, putting in indirect line as they continue north there.

As you move further out towards the northeast end of the fire here, the fire still remains fairly active. It’s a more remote area of the fire here. We do have crews and resources looking at indirect mines that will be coming across the 13 road down out towards the Mosquito Ridge Road. From there they’re going to continue to work out towards the east here, working their way out indirect out in front of the main fire here.

All these fires edges continues to remain pretty active and they’ll be working out here out in front of the main fire trying to put in indirect line as you move out here towards the east/southeast end of the fire. Very active fire front. As you come down through the southeast side of the fire, crews are working to come up indirect out of the Stumpy Meadows Reservoir coming up towards the northeast connecting existing fuel brakes that currently exist in this general area up towards the north to connect it from the crews coming down from the northern end.

As you come around the bottom end of the fire here we have some indirect lines that are proposed coming out of Pilot Creek. As we come out of Pilot Creek we’ll look at trying to come back around the southeast into the fire, back over towards the Wentworth Springs Road coming up through the network of roads where the fire is currently holding with a direct hand line and dozer line along the south end of the fire here.

As the fire got up and approached Volcano Road the crews were able to take aggressive action to stop the fire along Volcano Road. Currently it’s holding. They’ve been able to come out towards the west along the Volcano Road and they’re looking at coming off towards Buckeye Point back into the American River. They’re making good progress. They still have quite a fight on their hands but they’re making good progress coming out towards here and the fire activity will dictate how they continue to move forward.

Dozer lines on the north side of the community of Quintette. This piece right here has a lot of firefighters in here trying to pick this fire up direct as possible to keep it from continuing south into the community of Quintette. We’re going to continue to maintain a heavy presence down here until we can show containment and continue to mop up and secure this edge to where it’s safe to eventually repopulate that area and allow all of you to return to your residence.

Radio traffic reports show good progress on contingency and direct lines. Multiple helicopters work ahead of the ground resources to cool down areas. VLATs painted the west side between Quintette and Stumpy Meadows to slow progression of the fire. Lots of resources in that area and in Division H, the Deadwood Ridge area in the east.

September 10, 2022 at 2:38 PM

Yesterday resources were able to construct dozer and handline on the north side of Quintette to the community. Resources have been making progress building containment line on the northwest side of the fire. Last night fire growth was predominantly moving in a southeast and northeast direction.

Today with the onset of the low-pressure system, higher winds will move in which will fan the fire and increase activity. Fire crews will work to construct direct and indirect line around the perimeter of the fire. Additional resources will be working on perimeter control and preparing structures for defensive actions.

Both the El Dorado County Sheriff’s Office as well as the Placer County Sheriff’s Office are constantly monitoring and evaluating evacuated areas assessing the need for additional evacuations and when it is safe to repopulate.

September 9, 2022 at 4:20 PM

Update from Adam Coyan General Manager GDPUD (Georgetown Divide) on their water system. The system is fully operational and maintenance staff is on site, making sure the ditches are clear. Coyan stated that water utilization right now, with evacuations in effect, is actually higher than normal. Sprinklers around homes and more intensive irrigation to protect properties are the likely cause. Water conservation right now would be more appropriate, given the size and intensity of the fire. He also gave a shout-out to EID who offered any repair materials needed the district might not have readily on hand. To sum up, the Georgetown water system is fully functional.

We will remove the 3:11 pm update since we have been unable to confirm the radio traffic.

September 9, 2022 at 4:01 PM

El Dorado County has opened an overnight shelter for Mosquito Fire evacuees at Cameron Park Services District, 2502 Country Club Drive, Cameron Park, CA 95682. Overnight shelter, meals, showers, limited health services, and parking for trailers will be provided. Animals in crates and carriers will be accepted.

Please be prepared to evacuate IF the Evacuation Warning becomes an Evacuation Order. Those who require additional time to evacuate, including those with pets and livestock, should consider leaving now.

Today’s operational period saw the continued extreme growth of the Mosquito Fire, as it has now burned 13,704 acres and progressed into El Dorado County. Fire activity has included crown runs and spotting which is expected to occur throughout tonight. The winds and steep terrain have been in alignment which have combined to create the conditions conducive to the observed fire conditions.

This caused new evacuation orders to be issued by the El Dorado County Sheriff’s Office for the communities of Volcanoville, Georgetown, and Bottle Hill while Cool is under and evacuation warning. Additionally the Placer County Sheriff’s Office expanded its evacuation orders into Todd Valley.

The priority for firefighting personnel is the life safety of the community and structure protection. Additionally, the construction of direct and indirect containment lines utilizing handcrews and bulldozers is a significant objective. As the incident evolves, reconciliation of resources and the number of community members affected will continue to be updated

The Unified Commanders of the Mosquito Fire thank the community for their support and cooperation in adhering to evacuation orders and warnings, and remind those who are in an area when an evacuation order is implemented that it is time to leave. The decision to evacuate a community is done with the understanding of the inconvenience it places on those who live and work in a community, but also with the priority of life safety.

The IR flight last night had the following comments: The interpreters were able to designate the fire perimeter and isolated fires with no difficulty.
Large areas of perimeter growth and intense fire were detected along the western, northern, eastern, and southeastern perimeter of the Mosquito fire.
Large areas of intense fire were detected along the northern, eastern, and southeastern perimeter of the fire. One smaller area of intense fire was detected on the southwestern perimeter of the fire.
Large areas of scattered fire were detected throughout the majority of the fire.
The southwestern portion, while having some scattered fire, was relatively tame in comparison to the rest of the fire and was therefore omitted.
One intense isolated fire was detected outside the northern perimeter IVO a large patch of intense fire.

September 8, 2022 at 8:20 AM

Continued threat to power, water and communication infrastructure. The fire is in Unified Command between the Tahoe National Forest and CAL FIRE. CAIIMT 5 has been ordered for this incident.

September 8, 2022 at 7:31 AM

Fire is starting to be very active again. Reports of active fire near Cal Fire Station 11 and near the town of Foresthill.

September 8, 2022 at 6:01 AM

No change in evacuations overnight. The fire was mapped at 6,817 acres by FIRIS at 2:50 am. Additional heavy equipment arrived overnight.

September 7, 2022 at 8:51 PM

September 7, 2022 at 8:33 PM

Today the Mosquito Fire showed extreme fire behavior and growth, more than quadrupling in size to over 5,000 acres. Assigned personnel continued to improve existing control line and build new control lines, and also assessed and prepared structures threatened by the fire. The fire is burning in extremely difficult terrain including steep canyons where directly attacking the fire can be difficult.

The weather in the fire area will continue to be extremely hot and dry overnight and into tomorrow. Combined with very low fuel moistures fire conditions are likely to replicate today’s behavior during the overnight period and into tomorrow’s operational period.

It is incredibly important all those who receive an evacuation order leave the area immediately and it is recommended that those in an evacuation warning zone leave the area as well. Several updates to the evacuation order and warnings zones were made today to protect the life and safety of those who live and work in the fire area.

The Unified Commanders of the Mosquito Fire are aware of reports of damaged structures. The damage inspection process will be initiated when fire conditions allow.

September 7, 2022 at 8:10 PM

CAIIMT 5 (Young) Type 1 Team has been ordered for this incident.
