Low relative humidity values, dry conditions and strong north winds have created the perfect recipe for wildfires to spark Monday in the North Bay hills.
The risk for wildfire has led the National Weather Service to issue a red flag warning in Marin, Napa and Sonoma counties for elevations of 1,000 feet or above through 8 p.m. Monday.
Inland peaks in Napa and Sonoma counties will be particularly susceptible to fire today with north-northeast winds of 15 to 25 mph and gusts of 30 to 50 mph in the forecast, the National Weather Service said.
At 5 a.m. Monday, dry north winds were gusting to 51 mph on Mt. St. Helena (4,300 feet) and to 45 mph at Healdsburg Hills North (2,500 feet), according to the NWS.
The Sky Oaks watershed of the Marin Municipal Water District on Mount Tamalpais, Natalie Coffin Green Park in Ross, Leo Cronin parking lot in Lagunitas, and Mount Vision Road in Inverness are closed during the red flag period.
Mount Tamalpais State Park roads north of Panoramic Highway on Pantoll Road and Ridgecrest Boulevard are closed to motor traffic until 7 a.m. Tuesday and all park use permits north of Panoramic Highway are suspended, including filming.
The Marin County Fire Chiefs Association warns that any wildfire could spread rapidly and advises the public to exercise extreme caution, “especially with the use of equipment and machinery as well as smoking.”
All open burning and burn permits are suspended on public lands, officials said.
