LOS ANGELES (AP) — Large swaths of California are expected to see fire weather starting Thursday and thousands of people could lose power as utilities try not to spark wildfires during hot and windy conditions expected to last through Saturday.
Los Angeles Mayor Karen Bass, who has faced criticism for her city's response to deadly fires in 2025, said she's directed the fire department to deploy personnel and equipment ahead of the winds. The fire department has also
requested assistance from the state’s office of emergency services, she said.
“It’s a pretty widespread event of elevated fire weather, so the whole SoCal region should really be on alert,” said Rose Schoenfeld, a meteorologist with the National Weather Service.
Dry, warm and gusty northeast winds known as Santa Anas, which blow from the interior of Southern California toward the coast and offshore, are expected, with the strongest winds forecast for Thursday afternoon through Friday afternoon.
The winds are expected to reach 20 to 40 mph (32 to 64 kph), with gusts from 50 to 70 mph (80 to 113 kph), in the San Gabriel mountains in Los Angeles County and the Santa Susana mountains, which are mostly in Ventura County, Schoenfeld said. Elevated, though brief, critical fire weather conditions are also forecast for portions of the Santa Lucia mountains in San Luis Obispo County.
Dangerous conditions began earlier in Northern California, with some communities in the Sierra Nevada and its foothills experiencing strong winds, high temperatures and low humidity starting Wednesday night, the National Weather Service said.
The service issued a Red Flag Warning for parts of central and Northern California starting Thursday and lasting through Friday morning, saying that any fires would spread rapidly. Such warnings are issued when weather conditions create an increased risk of wildfires.
Pacific Gas and Electric Company had notified 88,000 customers in 29 counties as of Wednesday afternoon that it may need to proactively turn power off starting Wednesday night to reduce the risk of winds toppling over energized power lines that could start a fire.
The potential interruption in service to customers from the Central Coast to the upper corners of the Sierra Nevada could last through Saturday afternoon, the company said.
In Southern California, the Red Flag Warning for the mountainous areas in Ventura and Los Angeles counties will be in effect from Thursday morning through Friday night.
“We are augmenting our staffing, positioning our people and pre-deploying equipment ahead of this weather so we are ready before the first call comes in," Los Angeles Fire Chief Jaime Moore said. “We are asking residents to do their part, too. Clear the streets, have a plan and stay informed.”
In January 2025, the Palisades Fire — fanned by Santa Ana winds — ripped through a hillside Los Angeles neighborhood, killing 12 people and destroying mansions with spectacular ocean views. Another fire that burned at the same time in the city of Altadena, in Los Angeles County, killed 19 people and destroyed more than 9,400 homes and businesses.
Schoenfeld said the Santa Ana winds are not going to be as strong as during those fires, when they were gusting 60 to 100 mph (96 to 160 kph).
Authorities determined the Palisades Fire was a carryover fire from the Lachman Fire. The Eaton Fire was caused by sparks from an idle transmission tower owned by Southern California Edison, officials said.
Southern California Edison’s online dashboard on Wednesday showed it was considering public safety shutoffs that could affect 245,000 customers in Kern, Los Angeles, Santa Barbara, Tulare and Ventura counties. Most of those customers — 124,000 — are in Ventura County, just north of Los Angeles.
