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.

Here's the latest forecast for an upcoming winter storm that forecasters hope could finally lift Los Angeles County from the throes of 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.

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.

Forecasters believe there's little risk that the rains expected next week will trigger debris flows and mudslides in Southern California's recent burn areas.

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 next week.For Sunday, the highs will mostly be in the 60s and 70s,
