Firefighters are making progress slowing the major fires in the Los Angeles area that have killed five people, ravaged communities from the Pacific Coast to Pasadena and caused thousands of people to flee their homes.

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.

As wildfires roar into residential neighborhoods, firefighters in California and elsewhere are finding that water systems can’t keep up with the demand.
