With millions of people preparing to travel for the Thanksgiving holiday, two strong storm systems are forecast to bring high winds, heavy rain and snowfall to a large swath of the United States this week.

A low-pressure system headed for Northern California and Oregon is likely to bring extreme rain and strong winds.

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

A powerful storm is bearing down on the West Coast and bringing with it a scary-sounding weather term. That term is bomb cyclone.

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.

A powerful bomb cyclone is ripping the Pacific Northwest with hurricane-strength winds as the season’s first atmospheric river comes ashore in Northern California, promising torrential rains, floods and mudslides across the region.

A huge storm is predicted to hit Washington, Oregon, and California this week linked to atmospheric river weather systems.
