A massive plume of moisture from the Pacific called an atmospheric river will hit the West Coast on Tuesday afternoon and last into Friday.

Over a month’s worth of rain, hurricane-force wind gusts and feet of mountain snow are coming to parts of the Pacific Northwest and Northern California.

Residents of the northwest are bracing this week for an incoming atmospheric river poised to slam Northern California, Oregon and Washington this week, bringing heavy rain and potential hurricane-force winds to the region.
