More rain is falling on parts of Southern California after causing mudflows over the weekend. The rain is helping firefighters but boosting the risk of toxic ash runoff in areas scorched by Los Angeles-area wildfires.

Rain was falling across Southern California on Sunday, bringing some relief to thousands of firefighters battling multiple major blazes for nearly a month in the Los Angeles area, but also prompting new threats of floods and mudslides across burn-scarred lands.

Rain brought much needed aid to the Los Angeles firefight, moving the fires surrounding the city closer to containment.

Rain on the way to parched Southern California on Saturday will aid firefighters mopping up multiple wildfires.
