North Bay Red Flag Warning Set To Go Into Effect

NORTH BAY, CA — Forecasters with the National Weather Service San Francisco Bay Area have issued a red flag warning for North Bay mountains above 1,000 feet in Napa, Sonoma and Marin counties between 8 p.m. Saturday and 10 a.m. Sunday.

A red flag warning means critical fire weather conditions are either occurring now, or will shortly. A combination of strong winds, low relative humidity and warm temperatures can contribute to extreme fire behavior.

Northeast winds of 20-30 mph with gusts up to 35 mph will develop around sunset Saturday, and the highest threat of fire is in Napa County and northern Sonoma County.

There will be little overnight humidity recovery, and any fires that develop have the potential to spread rapidly, the National Weather Service said.

Hot and dry weather will continue Sunday afternoon with temperatures in the mid-80s and lower 90s.
