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.

The West Coast is in the middle of a long-lasting and potent atmospheric river event, which will bring days of heavy rain and mountain snow throughout the week ahead.
