With parts of Los Angeles County still smoldering from wildfires, the expected rain this weekend would seem like a welcome relief. But how the rain falls could make the difference between a disaster respite or a disaster repeat.

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.
