As of today, September 11, 2020, the fires known as the Elkhorn, Hopkins, Willow, Vinegar and the August Complex will now collectively be known as the August Complex. These fires have all burned together. The August Complex will be split into three zones: North, South and West. The intent is to simplify the coordination of effort, ordering and timely release of accurate information.

The August Complex will be managed under unified incident command between California Interagency Incident Management Team-Young (North Zone), Great Basin Team-DeMasters (South Zone) and CAL FIRE Team-Parkes (West Zone).

The California fire siege which began on August 15, 2020 has burned more than 2.5 million acres with firefighters responding to 7,657 fires. The collective August Complex alone has burned more than 726,000 acres. The fire is actively burning in the Shasta-Trinity, Mendocino, and Six Rivers National Forests and continues to threaten homes and communities within Humboldt, Mendocino, and Lake counties. Monitor your local news outlets, fire department, forest and county social media outlets for current updates and evacuation notices.

Firefighters worked last night to secure the line on the northern perimeter along the 35 Road (Shasta-Trinity National Forest), utilizing firing operations to remove vegetation and widen the containment along the dozer line. On the west and north west perimeter of the fire (Six Rivers National Forest), crews continue to provide protection for structures in the Ruth area. The goal is to try and push the fire north towards Horse Ridge and Soldier Basin, keeping it out of the valley. The east perimeter of the fire is in mop-up and patrol status. Today, while the weather has stabilized, we will continue to experience active fire behavior due to low relative humidity, steep terrain and very dry conditions in the forest.

Weather: High pressure will build back into the area causing an inversion which will keep smoke and haze over the fire area. The shading caused by the smoke inversion will keep temperatures lower and winds light. Relative humidity will be in the 11-13% range.

The Elkhorn, Hopkins, Vinegar Peak and Willow Basin Fires have merged and now will be known as the Elkhorn Fire. The Elkhorn Fire is burning on the Mendocino, Shasta-Trinity and Six Rivers National Forests. The reported increase in acreage and the reduction in percent contained are the result of the consolidation of all fires merging into one. The fire was very active again today with considerable fire growth on the west and southwest side of the fire. The fire is well established in the area around Island Mountain. Crews used existing fire lines and dozers to protect the area near Ruth as the active portion of the fire pushed north towards Horse Ridge and Soldier Basin. Firefighters also continued to work along the 35 Road, on the north perimeter near Murphy’s Glade, utilizing firing operations (burning out vegetation to widen the containment line) when conditions permit. The east perimeter of the fire is in mop-up and patrol status. Firefighters will continue to look for and extinguish all hot spots. Weather: Winds were very light across the fire area through the day with gusts less than 10 mph as dense smoke kept temperatures considerably lower. Relative humidity remained very low hovering in the 7-15% range.
