According to Weather Nation TV, a strong "bomb cyclone" driven by a Category 5 atmospheric river is predicted to erupt along the US West Coast this week, posing a threat of hurricane-force winds, devastating flooding, and heavy snowfall in the mountains.

According to the Xinhua news agency, millions of Americans from Washington State to Oregon and Northern California could be impacted by the powerful mid-latitude storm, which is predicted to strike Tuesday through Thursday.
According to Weather Nation TV, some coastal regions in California may experience level 4 impacts, which fall into the "extreme" category.

"This intense storm system is expected to bring major impacts to areas of the Northwest and northern California with heavy rain, strong winds, and big swells," it stated.
Narrow passageways in the atmosphere that have the capacity to transport substantial amounts of moisture are known as atmospheric rivers. Heavy precipitation is created when warm, humid air from the tropics cools down and collides with cold air from the Arctic.

When a cold and warm mass of air collide, a "bomb cyclone" is created. This intensifies a cyclone, bringing with it stronger winds and a higher chance of coastal flooding.
