Bomb cyclone in Northwest leaves hundreds of thousands without power, kills at least 1

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

The Weather Prediction Center issued excessive rainfall risks through Friday and hurricane-force wind warnings were in effect as the strongest atmospheric river - a large plume of moisture - that California and the Pacific Northwest have seen this season overwhelmed the region. The storm system that started hitting Tuesday is considered a bomb cyclone, which occurs when a cyclone intensifies rapidly.

Falling trees struck homes and littered roads across northwest Washington. In Lynnwood, Washington, a woman died Tuesday night when a large tree fell on a homeless encampment, South County Fire said in a statement on X. In Seattle, a tree fell onto a vehicle, temporarily trapping someone inside, the Seattle Fire Department reported. The agency later said the person was in stable condition.
