Severe flash floods and violent thunderstorms pounded the northeastern United States, putting millions in danger. A lightning strike killed a man in New Jersey as torrential rain sparked widespread rescues, long power outages, and major travel snags. In upstate New York, fast-rising water trapped cars, prompting flash flood warnings for Albany, Saratoga, Rensselaer, and Schenectady counties. Tens of thousands across multiple states remained without electricity, and major regional airports logged hundreds of canceled flights.
