Rain mostly moved out of Southern California on Monday after the first significant storm of the season brought weekend downpours that aided firefighters while causing ash and mud to flow across streets,

Less than an inch of rain fell in most areas, but it was enough to loosen Los Angeles hillsides burned bare by the recent blaze near the Pacific Palisades.

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