LOS ANGELES – Heavy rain fell across a large swath of Southern California on Feb 13 afternoon as the region braced for intense bouts of precipitation that began to flood roads and threatened to unleash debris flows in areas recently burned by wildfires.

More than 100 homes were under mandatory evacuation orders in the city of Los Angeles, Jim McDonnell, the Los Angeles police chief, said Thursday morning. The Palisades fire destroyed thousands of homes in the city’s Pacific Palisades neighborhood last month, and hillsides remain vulnerable in the area.

Los Angeles County is getting hit by severe weather Thursday night as burn scar areas may be at risk of mudslides.

In the Los Angeles area, the burn scars that carry the highest risk are those from the Eaton and Palisades fires from January and the Bridge Fire from the fall.
