A significant winter storm is causing widespread power outages across the United States, affecting approximately 350,000 customers as of Monday morning, with Michigan being the hardest hit. The storm is bringing blizzard-like conditions, heavy snow, and high winds, with gusts up to 75 mph, to parts of the Upper Midwest and Western New York. Authorities are warning of dangerous travel conditions, particularly in the Buffalo area, due to potential whiteout conditions and a significant drop in temperatures across the central U.S.
