Fire season is under way, and the Bay Area just received its first red flag warning.
The warning from the National Weather Service runs from 10 p.m. Sunday through 8 p.m. Monday for mountains at elevations of 1,000 feet or higher in parts of Marin, Sonoma and Napa counties.
A triple punch of high temperatures, low humidity and strong winds is expected to increase fire danger.
“Once rain season is kind of over, we head into fire season,” said Anna Schneider, meteorologist for the National Weather Service’s Bay Area office. “We’re expecting critical fire weather conditions to be occurring with strong enough winds and low enough relative humidity, as well as dry fields, which can lead to extreme fire behavior.”
Schneider said north and northeast winds are expected to pick up Sunday evening, with gusts of 30 to 40 mph Sunday night and reaching up to 50 mph at higher peaks. The humidity will range from 15% to 25%, according to the Marin County Fire Department.
