A sweeping winter storm battered large swaths of the United States, producing heavy snow, sleet and freezing rain that disrupted travel, forced thousands of flight cancellations and left hundreds of thousands without power. Major transit agencies altered operations, instituted detours and warned commuters of multi-day impacts; authorities urged residents to avoid nonessential travel and prepare for prolonged cold that complicates rescue and restoration. Visual coverage and agency briefings highlighted high-impact zones from the southern Rockies to New England and the logistical strain on road crews and utilities. Officials cautioned that restoring service and clearing routes will take time amid persistently low temperatures that heighten risks for vulnerable populations.
