Rain fell on parts of Southern California on Sunday and the scattered showers were expected to continue overnight, boosting the risk of toxic ash runoff in areas scorched by Los Angeles-area wildfires.

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.
