#California Issued Warning Over ‘Onslaught’ of #AtmosphericRivers

By Amanda Greenwood, Dec 17, 2025

"Following last week’s atmospheric rivers—which triggered flooding in the #Cascades and #WashingtonState—the #WestCoast is facing another series of storms, now shifting south. These systems are expected to bring heavy rain and mountain snow to #Oregon and #NorthernCalifornia from Wednesday into the weekend and next week, according to senior meteorologists at The Weather Channel.

"In summary, these meteorologists have forecast that Wednesday could bring heavy rain and high winds to the northwest and far northern parts of California, lessening to showers on Wednesday afternoon.

"Another atmospheric river will then hit #Oregon, Washington, #Idaho, and #Montana on Thursday, bringing snow and rain. By Friday, the system is expected to move into southern Oregon and northern California, particularly affecting areas north of the Bay Area. Over the weekend, there is a concern that northern California will be badly affected by rainfall on Sunday, with locally heavy rain forecast to return to Oregon and Washington.

"They've predicted that the heaviest rainfall is expected to fall over the weekend, in western Oregon and northern California, particularly #Siskiyou and coastal ranges along the California coast, where up to 5 inches of rain is forecast. This is likely to cause #FlashFlooding and possibly even #landslides—especially in areas that have recently experienced #wildfires.

"Already flooded areas in Washington—particularly the Skagit, Snohomish, Green, White, Cowlitz, Chehalis, and Yakima Rivers—could experience secondary crests, a later rise in river levels, from the additional rainfall. Although levels aren’t expected to be as high as last week, it could cause 'major flooding,' especially along the #SkagitRiver."
