The storm, driven by the season’s first major atmospheric river, inundated the region, killing at least three people and causing widespread power outages.

One of the strongest storms on the West Coast in decades knocked out power for thousands of people, unleashed strong winds that toppled trees and left two dead in Washington before making its way through Oregon to Northern California where on Thursday it dropped heavy snow and record amounts of rain.

A major atmospheric river has made landfall along the northern California coast and will rage on for days. From Washington to California, the impacts of this atmospheric river and bomb cyclone off the coast are widespread.
