Multiple wildfires, including the Palisades Fire and Eaton Fire, are raging across Southern California Thursday, leaving at least 10 dead and burning more than 27,000 acres, officials say. Police have arrested 20 suspected looters.

Wildfires menacing Los Angeles have killed at least 10 people and devoured nearly 10,000 structures, with five fires burning into a third night on Thursday, as dry desert winds fanning the flames again gathered strength.

The smoke was expected to most heavily affect northwest coastal LA County, and in areas nearest the Palisades, Eaton and Hurst wildfires.

The wildfires burning across LA are also degrading the air quality across the region. The resulting air pollution is a serious health threat, especially for children, pregnant people, older adults, and those with preexisting conditions.
