Most affected customers are located in the North Bay, East Bay hills and the western Sacramento Valley. Two polling places in Vacaville and one each in Los Gatos, Fairfield and Middletown could lose power Tuesday night.
“PG&E has delivered temporary generation for each of these polling locations,” the utility said in an update on its website. “However, if power needs to be shut off for safety, it would occur after in-person voting has ended.”
A red flag warning is now in effect across much of the Bay Area until Thursday morning, as the National Weather Service expects a strong offshore wind event to bring dry, gusty weather. That combined with low fuel moisture increases the risk of dangerous wildfires.
Gusts up to 70 mph are forecast at some high elevations, including the Geysers, Mount St. Helena and Mount Diablo.
Given recent rain, the Bay Area is at relatively low risk of major fires, according to UCLA climate scientist Daniel Swain. Parts of central and southern California, which haven’t yet had significant rainfall, could be more heavily affected.
PG&E expects the power shutoffs to last until Thursday when winds are expected to die down.
