Massive US winter storm halts travel as thousands of flights are canceled

A sprawling winter storm blankets much of the United States, canceling almost 12,000 flights over the weekend and triggering widespread power outages as about 140 million people—from New Mexico to New England—face winter storm warnings. The system brings heavy snow, dangerous ice, and extreme cold that could linger for days, prompting governors to declare emergencies, utilities to prepare for outages, and major hubs such as Dallas–Fort Worth, Nashville, and Charlotte to be hit hard while officials urge people to stay home and prepare for extended travel delays.
