LOS ANGELES—A storm that parked itself over Southern California for days, unleashing historic downpours that caused hundreds of landslides, was expected to move out of the region after one final drenching Wednesday, but authorities warned of the continued threat of collapsing hillsides.
One of the wettest storms in Southern California history unleashed at least 475 mudslides in the Los Angeles area after dumping more than a foot (30 centimeters) of rain in some areas, including the Hollywood Hills.
