LOS ANGELES (AP) — Rain eased on Monday after Southern California’s first significant storm of the season brought weekend downpours that aided firefighters but caused ash, mud and debris to flow across streets in wildfire-burned areas, while heavy mountain snow forced the shutdown of a major interstate north of Los Angeles.

Rain was falling across Southern California on Sunday, bringing some relief to thousands of firefighters who have been battling multiple major wildfires in the LA area.
