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.

More rain is on the way after Redding got 8 inches of rain in three days due to an atmospheric river. Here's a weather update.

"We do have a Flood Watch in effect across the area from this afternoon to late Tuesday night," Kurth said. "Much of the Sacramento area will be relatively dry early and then we'll see precipitation spreading from north to south through the day. So, afternoon and especially tonight we'll see some of that moderate to heavy rain."

Places like California, Oregon, Washington, Idaho, Utah and Nevada are (somewhat) used to this sort of phenomenon. You can see how this week's "river" grabs all that moisture from the Pacific and flings it onland.

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.

A long-duration atmospheric river is set to bring moderate to heavy rain in northern and central parts of California, but south of Los Angeles will likely get a few light, scattered showers this week.

Southern California will see a slight uptick in temperatures on Sunday as the region braces for an atmospheric river that's expected to bring a deluge of rain this week. For Sunday, the highs will mostly be in the 60s and 70s,

It could rain for many hours each day in the middle of next week as the edge of one of these storms takes a swing into Southern California, forecasters say.
