PG&E restored hundreds of customers’ power Saturday morning with at least a dozen still without power after hazardous winds and a two-day heat wave caused outages through the weekend, according to a spokesman..

PG&E spokesman Jeff Smith said Saturday that 11 customers in Alameda County and another one in Contra Costa County still awaited power restoration on Saturday morning. He said public safety power shutoffs affected about 695 customers in Alameda County and 275 in Contra Costa County due to “high winds, low humidity and dry vegetation.”

“All customers will be restored by Sunday evening,” Smith said.

This came after strong, gusty winds blew into the region, stifling what the National Weather Service deemed a “near-critical fire weather threat” earlier this week.

Smith said the utility did not expect any further outages through the weekend.

Firefighters this week tackled several significant fires in the Bay Area, including the Somersville Fire in Antioch which injured one person and burned more than 350 acres on Wednesday. The Mission Fire scorched 64 acres Tuesday morning east of Fremont near the intersection of Mission and Andrade roads, and the Ranch Place Fire seared 92 acres between Tuesday evening and Wednesday morning in the East San Jose foothills.

As of Saturday morning, PG&E’s website reported several counties under shutoff warnings including Alameda, Colusa, Contra Costa, Fresno, Glenn, Merced, Monterey, San Benito, San Joaquin, San Luis Obispo, Santa Clara, Shasta, Stanislaus, Tehama, Trinity, Kern, Kings, Santa Barbara and Sutter.
