Don't be fooled by the cool weather. A combination of extremely low relative humidity and locally strong winds make for critical fire weather in the North Bay this weekend.
Marin County, CA -- The National Weather Service has issued a Red Flag Warning for the North Bay Mountains and other parts of the Bay Area, which is in effect until Sunday, November 11 at 4:00PM PST.
A Red Flag Warning means that critical fire weather conditions are expected during this time frame with a combination of extremely dry air (relative humidities below 10%) and locally strong winds.
The affected area includes higher terrain areas of Marin, Napa, Sonoma counties. The concerns of this weather system are that fires that develop will likely spread rapidly.
Marin fire agencies will be increasing staffing as conditions change throughout the county during the Red Flag Warning. Residents are advised to exercise extreme caution during the Red Flag Warning because a simple spark could cause a major wildfire, including the use of equipment and machinery as well as smoking.
Marin County Fire Agencies are now coordinating to distribute Red Flag Warning Announcements through "Nixle". It is important that ALL Mari residents register for Alert Marin AND Nixle, and understand the difference (they are different, and each requires a separate registration - and each is important during an emergency). To ensure you continue receiving Red Flag Warning and Emergency Alerts, please register for both Alert Marin and Nixle TODAY! Visit: www.alertmarin.org and www.nixle.com to register.
From the National Weather Service:
Offshore flow is forecast to strengthen Saturday night and persist through Sunday afternoon. Winds will be strongest over the higher terrain of the North Bay Mountains, East Bay Hills and the Santa Cruz Mountains. Gusty winds combined with already critically low relative humidity values and very dry fuels will create critical fire weather conditions. Winds are forecast to decrease on Sunday evening but very dry conditions will persist into Monday.
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
Defensible space is essential to improve your home’s chance of surviving a wildfire.
