Red Flag Warning In Effect for Marin County

The Marin County Fire Chiefs Association just shared the following information for immediate release: 

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 from 11 PM this evening to 5 PM Thursday, September 20. This supersedes the Fire Weather Watch that was previously in effect.

A Red Flag Warning means that critical fire weather conditions are expected during this time frame with a combination of strong off shore winds with gusts to 35 miles per hour and low relative humidity ranging from 25-35 percent.

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.
