Southern California wildfire destroys many structures; governor declares state of emergency

A wildfire whipped up by extreme winds swept through a Los Angeles hillside dotted with celebrity residences Tuesday, burning homes and forcing the evacuation of tens of thousands of people.

A wildfire whipped up by extreme winds swept through a Los Angeles hillside dotted with celebrity residences Tuesday, burning homes and forcing the evacuation of tens of thousands of people, some of whom abandoned their cars and fled on foot to safety with roads blocked.

California Gov. Gavin Newsom, who was in Southern California to attend the naming of a national monument by President Joe Biden, made a detour to the canyon to see "firsthand the impact of these swirling winds and the embers," and he said he found "not a few -- many structures already destroyed."

Officials did not give an exact number of structures damaged or destroyed in the Pacific Palisades wildfire, but they said about 30,000 residents are under evacuation orders and more than 13,000 structures were under threat.

And the worst could be yet to come. The blaze began around 10:30 a.m., shortly after the start of a Santa Ana windstorm that the National Weather service warned could be "life threatening" and the strongest to hit Southern California in more than a decade. The exact cause of the fire was unknown and no injuries had been reported, officials said.

The winds were expected to increase overnight and continue for days, producing isolated gusts that could top 100 mph (160 kph) in mountains and foothills -- including in areas that haven't seen substantial rain in months.

"By no stretch of the imagination are we out of the woods," Newsom warned residents, saying the worst of the winds are expected between 10 p.m. Tuesday and 5 a.m. Wednesday. He declared a state of emergency on Tuesday.

As of Tuesday evening, 28,300 households were without power due to the strong winds, according to the mayor's office. About 15,000 utility customers in Southern California had their power shut off to reduce the risk of equipment sparking blaze. A half a million customers total were at risk of losing power preemptively.
