Overview
- More than 105 million people are under National Weather Service alerts for freezing conditions, winter weather and lake-effect snow across the eastern two-thirds of the U.S.
- Lake-effect bands are producing hazardous travel near the Great Lakes, with winter storm warnings around Chicago and localized totals projected up to 12–18 inches in parts of Indiana, Wisconsin, Michigan and West Virginia.
- Gusts of roughly 20–35 mph are creating dangerous wind chills in the teens and single digits in spots, with officials warning of slick roads, reduced visibility and isolated tree or power issues.
- Freeze watches and warnings stretch across the South, including parts of Florida, with possible record lows in Alabama, Mississippi and Tennessee and local agencies urging preparations for plants, pets and vulnerable residents.
- Many areas are seeing the season’s first accumulating snow, with the most intense impacts expected Monday into Tuesday before temperatures moderate beginning Wednesday.
