June 21, 2018 – The National Weather Service in Sacramento has issued a Red Flag Warning, which is in effect from midnight Friday night to 8 PM Sunday. The Fire Weather Watch is no longer in effect.
Dry and gusty northerly winds are expected over portions of the northern Central Valley and surrounding foothills this weekend. The strongest winds are forecast to be on the west side of the Sacramento Valley, west of Interstate 5, and into Solano County. This band of strong winds will also affect the foothills of the Coastal Range, including Lake County. Locally dry gusty winds are also possible over the Northeast Foothills of the Sacramento Valley as gusty downslope winds develop Saturday night.
* Wind: North winds 15 to 20 mph with gusts around 30 mph.
* Humidity: Afternoon minimum humidities as low as 6-12 percent and areas of very poor overnight recovery.
* Impacts: Any fires that develop will likely spread rapidly.
A Red Flag Warning means that critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity, and warm temperatures can contribute to extreme fire behavior.
