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.

Areas charred by last month's wildfires in Southern California now face a new threat from a powerful, but fast-moving Pacific storm. Here's what you need to know about this threat.

A monster rainstorm was drenching southern California on Thursday, with officials in Los Angeles readying for flooding and landslides in areas burned by last month's huge wildfires.

A massive amount of rainwater and mud was unleashed onto Pacific Coast Highway on Thursday, sweeping an L.A. Fire Department vehicle off the iconic coastal route and prompting an indefinite road closure roughly from Santa Monica to the Malibu Pier.

The damage comes as L.A. County endures an atmospheric river storm, bringing torrential rainfall and the possibility for “life-threatening” debris flows to a region weary from last month’s devastating firestorm.
