Red flag fire warning extended

SAN FRANCISCO

High winds and low relative humidity in the hills with elevations above 1,000 feet prompted the weather service to issue a red flag fire warning Tuesday at 11 p.m., NWS forecast Steve Anderson said.

The fire warning was initially scheduled to expire at 6 a.m. Thursday but has been extended to last through 5 p.m. Thursday, Anderson said.

The warning has been issued to advise fire agencies of hot and windy weather conducive to fast-spreading fires.

A wind advisory also issued Tuesday night will last through noon today, Anderson said. High winds of 25 mph to 35 mph with gusts up to 50 mph are expected in the North Bay and East Bay hills with elevations above 1,000 feet, Anderson said.

Weather officials will reevaluate conditions today to determine if the wind advisory will be reissued, according to Anderson.
