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 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.

Bomb cyclone is a term used by weather enthusiasts to describe a process that meteorologists usually call bombogenesis. It's the rapid intensification of a cyclone in a short period of time, and it can happen during powerful storms such as the one no rthern California and the Pacific Northwest are preparing for this week.

According to the National Weather Service, the last example of a 'bomb cyclone' was Hurricane Milton which made landfall in Florida last month.

A Pacific storm is undergoing what meteorologists call bombogenesis while also hauling in an atmospheric river of moisture.

As the strongest atmospheric river that California and the Pacific Northwest has seen this season bears down on the region, the Weather Prediction Center issued excessive rainfall risks beginning Tuesday and lasting through Friday.

A bomb cyclone fueled by an atmospheric river will swing by the Pacific Northwest this week, bringing heavy rain and snow to the region between Tuesday night and Friday morning.
