Northwest US faces major disruptions as powerful bomb cyclone brings high winds and heavy rain

A powerful storm system is affecting the northwest United States and British Columbia, Canada. The storm is classified as a "bomb cyclone", which is a rare weather phenomenon where a cyclone rapidly intensifies. The storm is also characterized by a strong atmospheric river, a long stream of moisture in the atmosphere, which is causing excessive rainfall, high winds, and significant snowfall. The Weather Prediction Center has issued excessive rainfall risks for Tuesday through Friday, and the region is expected to receive over a month's worth of rain. The storm has already caused widespread power outages, tree damage, and at least one reported fatality.
