Flooding, mudslides and debris flows caused by the heaviest rain in Los Angeles and southern California in a year shut Pacific Coast Highway from approximately Santa Monica to the Malibu Pier.

On Friday, the storied coastal road had dissolved into a river of mud and debris after a powerful rainstorm sent those burned hillsides careening toward the ocean, turning canyons into rivers of mud and rocks.

As Southern California recovers from last month’s devastating wildfires, heavy rains Thursday resulted in pockets of flooding, blocked roadways and mud piling up around recent burn scars.

A Los Angeles City firefighter was hospitalized after his SUV was swept into the Pacific Ocean during a mudslide in Malibu.

An atmospheric river is expected to bring torrential rain to California this week, threatening parts of the state with flash floods and mudslides.
