Officials closed part of Pacific Coast Highway in the Palisades fire area on Sunday, Caltrans said, as rain poured down across the Los Angeles area and burn scars in Southern California were under a flood watch that will last until 4 p.m. Monday, according to the National Weather Service.
On social media, Caltrans said mudflows in Topanga Canyon prompted the isolated closure of PCH west of Topanga Canyon Boulevard.
The Los Angeles Fire Department separately announced the closure of a stretch of Palisades Drive because of a mudflow.
Dozers were working to clear the area, and there was a closure at Sunset Boulevard and Palisades Drive.
Assorted road closures were announced by agencies Sunday because of the fire and flood concerns, including Malibu Canyon between Piuma Road and Francisco Ranch Road.
Meteorologists warned of floods as rain began Saturday and continued Sunday. While the rain can help alleviate dry conditions that helped fuel wildfires across the region, the hills can’t absorb water after vegetation has burned, leading to debris flows, flooding and mudslides.
Flood watches were issued from 4 p.m. Sunday until 4 p.m. Monday for areas impacted by the Palisades and Franklin fires in the Pacific Palisades and Malibu, the Eaton fire in Altadena and Pasadena, the Hughes fire around Lake Castaic and the Bridge fire in the Angeles National Forest north of Glendora.
