LOS ANGELES - A mudslide caused by rain in the Palisades Fire zone blocked a stretch of Pacific Coast Highway Friday. CalTrans and public works crews were monitoring a hillside along PCH near Big Rock Drive after loosened soil carrying rocks and debris fell onto the road. A bulldozer was used to clear a path for traffic.

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.

Hours of heavy rain triggered mud and debris flows along the Pacific Coast Highway in Malibu and on Palisades Drive in Pacific Palisades overnight. Video around 3 a.m. showed a mudslide blocking the northbound side of PCH at Big Rock Road in Malibu.
