NWS Issues Red Flag Warning For North Bay Mountains

Red Flag Warning 10-5-19

October 5-6, 2019

Warning in effect for elevations above 1000 feet Saturday evening through 10AM Sunday morning.  

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 above 1000 feet, which is in effect from 8 PM Saturday to 10 AM Sunday.

A Red Flag Warning means that critical fire weather conditions are expected during this time frame. The National Weather Service has forecasted a combination of strong off shore winds with gusts to 20-35 miles per hour and low relative humidities ranging from 18-28%.

The affected area includes 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.

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)
  • All open burning and burn permits are suspended on public lands
  • 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.

  • The Mount Tamalpais State Park information number is 415-388-2070.
  • The Marin Municipal Water District information number is 415-945-1195.
  • The Marin County Fire Information Hotline number is 415-473-7191

Note: The original message incorrectly noted on one line that the Red Flag Warning was in effect until Wednesday.  The current forecast has the Warning in effect until Sunday at 10AM.  The message also indicated that Marin fire agencies were staffing additional fire engines for this event.  This was not correct.  We apologize for any confusion this caused.
