Multiple wildfires, including the Palisades Fire and Eaton Fire, are raging across southern California Thursday, leaving at least 5 dead and burning more than 27,000 acres, officials say. Police have arrested 20 suspected looters.

The wildfires that destroyed homes in multiple sections of the Los Angeles area will test California’s efforts to stabilize the state’s insurance marketplace after many insurers stopped issuing residential policies due to the high fire risk.

It’s too soon to know the financial cost of the wildfires burning around Los Angeles. But the toll on California’s troubled insurance market could be enormous.
