Los Angeles County could see power outages as Santa Ana winds hit Southern California

Southern California Edison crews replace wooden poles with fire-resistant composite ones. The utility is weighing whether to proactively shut off power to more than 100,000 customers in the face of wind-driven fire threats.

While millions in Northern California suffered through a massive power outage that began early Wednesday, residents in Southern California wondered whether they could see the same blackouts as officials deal with strong winds that could spark fires.

Southern California Edison said that, given the strong Santa Ana winds forecast for the area, power could be cut off to more than 173,000 customers in parts of nine counties.

The outage could affect customers in Los Angeles, San Bernardino and Riverside counties, as well as areas in Orange and Ventura counties and portions of Kern, Tulare, Inyo and Mono counties.

The Los Angeles Department of Power and Water has no plans to shut off power to residents in the city because L.A. is highly urbanized with fewer wildfire-prone areas and an “extensive fire suppression infrastructure,” according to the utility.

Robert Villegas, an Edison spokesman, said Wednesday afternoon that the utility was continuing to monitor weather conditions with ground crews before deciding whether to switch off the power. He said Edison could not predetermine where — or when — shutoffs might take place.

“There’s no real way to know when that will be,” Villegas said. “We’re all waiting on the weather.”

The utility will make decisions on a “circuit by circuit basis,” he said, with each circuit providing service to 10 to 50 customers.

The National Weather Service has issued red flag warnings for parts of Southern California.

San Diego Gas & Electric officials say the utility might have to temporarily shut off power to about 30,000 customers beginning Thursday.

“If we do turn off power, it will stay off until we can safely restore it,” the utility said in a statement.

SDG&E officials said they warned customers in fire-prone areas of the county about the potential preventive shutoffs, known as “Public Safety Power Shutoffs,” via outbound dialer calls, texts and emails Tuesday evening.

The mountains and valleys of San Diego County will be under a red flag warning from noon Thursday to 6 p.m. Friday with the expected arrival of Santa Ana winds.
