"In the North Bay, 920 PG&E customers are without power," said utility spokesman J.D. Guidi.
Power is out for 1,862 customers in the Peninsula; 265 in San Francisco; 72 in the East Bay; and 141 in the South Bay. There is no estimated time for when power will be restored, Guidi said.
The numbers are promising considering a major storm earlier this month knocked out power to over a million PG&E customers.
Periods of heavy rainfall are expected until 6 a.m. Saturday, meaning more power outages may occur, the utility said.
