New York:
Severe thunderstorms across the U.S. Northeast on Sunday slowed operations at airports, wreaked havoc at outdoor sporting and musical events and sent people scurrying from a beach after three men were struck by lightning.
The men were injured at Orchard Beach on Pelham Bay in the Bronx on Sunday evening as bad storms rolled through the area, the Fire Department of New York said. The men were being treated at a hospital, and the extent of their injuries was unknown.
Torrential rain, thunder and lightning interrupted Labor Day holiday weekend celebrations in Philadelphia, where a parkway hosting a music concert was evacuated for safety reasons. Organizers of the Made in America festival warned people to move quickly and calmly to the exits and to protected areas outside the downtown festival site.
The bad weather also forced the early end to the Electric Zoo musical festival on an island in New York's East River and halted play at the U.S. Open tennis tournament in Queens.
Electric Zoo spokesman Stefan Friedman said "the safety and security of all attendees, artists and staff" was the primary concern as people were told to leave. The decision was made about six hours before the electronic music festival was scheduled to end on Randall's Island, which fans have to reach by ferries and shuttle buses.
Dozens of commercial flights into the city's airports were delayed because of the severe weather.
The National Weather Service said it had reports of wind damage and flash flooding in East Orange, New Jersey, and reports of large tree branches down on Long Island. It said most of the damage was reported between 4:20 p.m. and 5:15 p.m., when the storms were intense.
