Bomb cyclone sweeps across US after hitting Pacific Northwest

A powerful storm, called a "bomb cyclone," hit the Pacific Northwest late Tuesday and is now moving across the U.S. It has caused widespread power outages, affecting about 500,000 people in Washington, and resulted in tree damage and fatalities. Winds reached over 59 mph in Seattle, with higher elevations experiencing gusts of 60 to 80 mph. The storm is bringing a significant drop in temperatures, with many areas seeing a shift from mild November weather to colder, snowier conditions. Blizzard warnings are in effect for parts of North Dakota, while South Dakota and Minnesota are expected to face winter weather. The Appalachians will see their first measurable snow of the season on Thursday, with various winter weather advisories issued from Tennessee to New York.
