Southern California was primed for more mudslides and flooding on Friday, especially in areas scorched by last month's devastating wildfires, even as heavy rains that have saturated the Los Angeles area this week tapered off.

As the downpour intensified Thursday, the National Weather Service issued flash flood and severe thunderstorm warnings for a swath of eastern Los Angeles County. The rain caused a rockslide and pushed mud onto the road in Malibu Canyon, and a large debris flow left about 8 inches (20 centimeters) of mud across a road in the Hollywood Hills.
