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.

Southern California's first major storm of the season brought rain and snow, helping to extinguish wildfires but causing mudflows and road closures. Emergency crews worked to clear debris, and the storm disrupted schools and transport routes.

Mudflows prompted the closures of at least some roads, including in Topanga Canyon and on parts of the Pacific Coast Highway.
