A stronger atmospheric river is set to hit Northern California on Monday and then hit L.A. County on Tuesday, aiding hopes of helping end a devastating fire season.

The second peak of an ongoing atmospheric river storm arrived in Northern California Monday afternoon, prompting flood watches and a winter storm warning up in the Sierra.

Heavy rain and snow will hit Northern California throughout most of this week as an atmospheric river moves through.

It could rain for many hours each day in the middle of next week as a storm takes a swing through Southern California, forecasters say.
