PG&E is now warning customers in its service region of possible power outages in the coming days as the weather moves into Northern and Central California.
Temperatures are expected to drop by the end of Tuesday as a light weather system brings some chances of showers at higher elevations.
Strong winds and low humidity are the biggest concerns after that system. A red flag warning will be in effect for the Sacramento Valley and Bay Area from Thursday evening through Saturday, according to the National Weather Service.
The high fire danger has prompted PG&E to list Thursday through Saturday as days when power shutoffs for public safety are likely.
The counties that could be affected by the closures could vary from day to day, PG&E shows on the PSPS website.
In total, PG&E says about 28,000 customers could be affected.
