Red Flag Warning

October 9-10, 2019

Red Flag Warning Issued for Marin to remain in place until Thursday evening. PG&E to activate Public Safety Power Shiutoff (PSPS) protocols in parts of Marin.

Marin County, CA — The National Weather Service has issued a Red Flag Warning for the North Bay Mountains, interior valleys and other parts of the Bay Area, which is in effect from 5 AM Wednesday to 5 PM Thursday.

This event has the potential to be the strongest offshore wind event in the area since the October 2017 North Bay Fires.

A Red Flag Warning means that critical fire weather conditions are expected during this time frame with a combination of strong offshore winds with gusts to 55 miles per hour 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 two strike teams (10 engines), three water tenders, two Hand Crews, the North Bay Incident Management Team and additional Dispatchers and Chief Officers throughout the county during the Red Flag Warning.
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
  • Mount Vision Rd, Inverness (National Park Service)

  • Closures to Mount Tamalpais State Park – Roads north of Panoramic Highway are closed to motor vehicle traffic on Pantoll Road and Ridgecrest Boulevard.  All park use permits north of Panoramic Highway are suspended, including filming.

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.
