SEATTLE (AP) — A major storm swept across the northwest U.S., battering the region with strong winds and rain, causing widespread power outages and downing trees that killed at least one person.

At least one person is dead and hundreds of thousands of were without power early Wednesday as a powerful bomb cyclone hit the Pacific Northwest and northern California.

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 northern California and the Pacific Northwest are preparing for this week.

A powerful winter storm brewing near the Pacific Northwest known as a bomb cyclone is dragging an atmospheric river.

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.

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.
