Red Flag Warning Issued For North Bay

CALIFORNIA — The fire season's first red flag warning has been issued for parts of the North Bay, prompted by high winds and dry conditions, the National Weather Service said early Sunday.

The warning is in effect for elevations 1,000 and above in the North Bay from 10 p.m. Sunday to 8 p.m. Monday.

Red Flag Warning has been issued for the North Bay mountains (1000 feet and above) for 10pm SUN through 8pm MON.

The service says inland peaks in Napa and Sonoma counties are particular areas of concern, where north-northeast winds of 15 to 25 mph and gusts of 30 to 50 mph are expected Sunday night.

While wind speed is expected to ease by Monday, conditions will be drier, with relative humidity will drop from 30 to 40 percent to 10 to 25 percent.

Mild mountain temperatures of 55 to 65 degrees are forecast overnight Sunday.

"The combination of the offshore winds, lowering relative humidity values, and dry fuels will likely lead to critical fire weather conditions for the higher elevations of the North Bay," the NWS said in an advisory.
