A red flag warning due to wildfire weather conditions is set to last from 11 p.m. Wednesday to 5 p.m. Thursday in the mountainous parts of Napa and Sonoma counties.
Most at risk in the Greater Bay Area is the high elevation of eastern Napa County. PG&E has refined its Public Safety Power Shutoffs program, this time, mostly north and east of the Greater Bay Area.
Pacific Gas and Electric on Tuesday announced they are preparing for a possible Public Safety Power Shutoff (PSPS) on Wednesday, due to weather conditions that could spark wildfires.
