“Rainfall rates between 0.25 and 0.50 inches per hour will be common, with local rates up to 0.75 inches per hour across foothills and mountains.

Power was out Monday afternoon to an estimated 25 Southern California Edison customers in Malibu, according to the utility company’s outage map. The cause of the outages was listed as “equipment problems” for five customers and “pole upgrade” for the other 20. Earlier in the day, just before 11 a.m., the City of Malibu reported 60 customers were without power due to a “transformer explosion” that knocked out power to the Serra Retreat neighborhood.

Traffic on Malibu’s canyon roads was affected due to minor rockslides, with slowdowns on Malibu Canyon Road near the tunnel and Encinal Canyon Road above Fire Camp 13, both due to debris/boulders in the roadway, according to the California Highway Patrol.
