Red Flag Warning In Effect for Marin County--Warning to remain in place until Monday evening

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 from 8 PM this evening to 5 PM Monday October 8th.

A Red Flag Warning means that critical fire weather conditions are expected during this time frame with a combination of strong North East winds with gusts to 50 miles per hour and low relative humidity.

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.

The following land use 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.

  • Closures at Sky Oaks, Natalie Coffin Green Park (Ross), and Leo Cronin Parking Lot, MMWD
