A wildfire whipped up by extreme winds swept through a Los Angeles hillside dotted with celebrity residences Tuesday, burning homes in Pacific Palisades and prompting evacuation orders for tens of thousands.

In the frantic haste to get to safety, roadways were clogged and scores of people abandoned their vehicles and fled on foot, some toting suitcases. The traffic jam on Palisades Drive prevented emergency vehicles from getting through and a bulldozer was brought in to push the abandoned cars to the side and create a path, according to the LA Fire Department. 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.”

Palisadeswildfire, but they said about 30,000 residents were 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 aSanta Anawindstorm 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.
