Heavy overnight rain sent mud flowing onto the Pacific Coast Highway, leading to a full shutdown of the highway between Malibu and Santa Monica Friday, authorities said.

The stretch of the highway along the Pacific Ocean between Santa Monica and Malibu reopened to regular traffic. Some local officials believe it is too soon.

Heavy rains in Southern California have led to mudslides and the closure of the Pacific Coast Highway in Malibu for safety reasons, with cleanup efforts underway.
