UPDATED PG&E on Tuesday afternoon removed Santa Clara and San Mateo counties from the list of Bay Area counties where residents may be without power in a Public Safety Power Shutoff that may start Wednesday morning.
The electricity and gas provider added parts of Santa Clara and San Mateo counties Monday afternoon to the others that may be affected by the shutoff that is expected to last through Thursday. On Tuesday afternoon, PG&E announced six counties would no longer be impacted: Alameda, Contra Costa, Marin, Santa Clara, Santa Cruz and San Mateo.
Mountain View was not expected to lose power as part of the shutoff.
PG&E shuts off power to areas where there is a high risk that damaged electrical equipment will spark a catastrophic wildfire.
Monday morning PG&E began notifying 264,000 customers in 22 counties about a potential Public Safety Power Shutoff starting Wednesday morning.
By Monday afternoon, the numbers had grown to 303,000 customers and 25 counties. The numbers changed because the weather forecast changed, PG&E officials said.
The shutoff is in response to expected high wind gusts and dry conditions in the Bay Area and other parts of California.
The eight Bay Area counties and the number of customers that would be affected by the shutoff are Alameda, 12,200; Contra Costa, 23,230; Marin, 23,440; Napa, 11,180; Solano, 1,970; Sonoma, 39,940; Santa Clara, 2,978; and San Mateo, 70.
It would be the sixth Public Safety Power Shutoff this year.
PG&E said it will notify the potentially affected residents again 24 and four hours prior to the shutoff. Customers who have provided their contact information to PG&E will be notified by phone, text and email.
PG&E said it will again open Community Resource Centers where restrooms, bottled water, electronic device charging and air conditioning will be provided for up to 100 people at each center. The locations will be available at pge.com/pspsupdates.
The resource centers also will provide snacks, ice, blankets and a heater, according to PG&E.
