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.

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.

The second in a pair of back-to-back storm systems moved across Southern California overnight, triggering small mudslides in the Palisades Fire burn area and keeping public works crews and first responders on alert.
