SAN FRANCISCO (CBS SF) — With an approaching weather system expected to bring dry, gusty offshore winds to Northern California late this weekend, Pacific Gas &E Electric Company may cut off power for thousands of customers in 32 counties beginning Monday morning.

The utility announced Saturday that 44,000 customers in parts of 32 counties — including Alameda, Contra Costa, Napa, Solano and Sonoma counties — may lose electricity Monday. PG&E is sending these customers two-day notices. Seven tribes also may be affected.

The potential weather system combined with extreme to exceptional drought and extremely dry vegetation, could pose an increased fire risk, PG&E said.

The utility activated an Emergency Operations Center on Friday to support the weather event.
