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.

The Pacific Coast Highway along Malibu canyon was closed after runoff pushed mud and debris over the road and into the Pacific Ocean (Video Credit: @PIOErikScott).
