The recent storm brought some much needed moisture to Southern California without the dangerous mudslides some feared. But did it help reduce the fire danger?

Much-needed rain has begun to fall over Southern California, bringing relief to the drought-stricken region but also the threat of toxic runoff.

Heavy rain beginning Sunday afternoon caused some mudslides, and snow closed part of Interstate 5 near Los Angeles.

LOS ANGELES — More rain fell Monday on parts of Southern California after causing mudflows over the weekend, helping firefighters but 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.
