And the severe weather isn't over for California, "as the heaviest rains shift southward into portions of Central to Southern California" on Monday, the weather service's Storm Prediction Center said.

"This will pose a threat of flash flooding and debris flow problems across recent burn scar areas."

California just suffered its worst summer drought on record, along with a spate of wildfires.

But there's a bit of good news with the recent rain.
