Weather conditions predicted for this weekend, Saturday through Monday are CRITICAL in all parts of Marin. The Fire Weather Watch has been upgraded to a Red Flag Warning. The National Weather Service is predicting conditions similar to, or potentially exceeding, what was observed during the North Bay fires of 2017. Extreme fire weather conditions will impact Marin county. The weather service referred to the forecasted winds as "historic." We aren't taking this warning lightly at FIRESafe MARIN, and neither should you. Prepare TODAY.
Marin County, CA -- The National Weather Service has issued a Red Flag Warning and High Wind Advisory for the North Bay Mountains, interior valleys and other parts of the Bay Area, which is in effect from 8 PM Saturday to 11 AM Monday.
Pacific Gas & Electric Company (PG&E) has notified the County that it may activate its Public Safety Power Shutoff (PSPS) protocols in Marin County.
A Red Flag Warning means that critical fire weather conditions are expected during this time frame with a combination of extremely strong north to northeast winds, with gusts up to 80 mph possible across the highest peaks and low relative humidity ranging from 10-20%.
The affected area includes both lower and higher terrain areas of Marin, Napa, Sonoma, and East Bay counties.
The concerns of this weather system are that fires that develop will likely spread rapidly.
California Governor’s Office of Emergency Services (Cal OES) and CAL FIRE have approved the strategic prepositioning and increased staffing of critical fire resources to include one strike teams, two water tenders, 1 fire Dozer, and additional Dispatchers and Chief Officers throughout the county during the Red Flag Warning.
The following landuse restrictions are in effect for the Marin Municipal Water District, Mount Tamalpais State Park, Marin Open Space, and The Point Reyes National Seashore during the Red Flag conditions.
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.
