Severe thunderstorms drove more than 2,000 flight cancellations Tuesday across the United States, with more than 5,000 other flights delayed. The disruption hit airports in the New York City area, Boston, Philadelphia and Washington, D.C. hardest as the storms moved through the East Coast.
At least 7,000 flights were disrupted in all, and the Federal Aviation Administration issued ground stops for at least eight U.S. airports. Several U.S. airlines also issued travel advisories and flexible rebooking options for affected passengers.
JFK and New York City area
Nearly 600 departing flights had been canceled in the New York City metropolitan area alone Tuesday, along with more than 500 other flights that were delayed. John F. Kennedy International Airport was still running an average ground delay of about four hours Tuesday afternoon, even as it was not under a ground stop at that point.
That gap matters for travelers trying to leave the region. A ground stop pauses departures at a specific airport, while a ground delay adds waiting time without fully stopping operations, so a traveler at JFK could still face a long delay after a stop had already lifted elsewhere.
FAA ground stops and storms
The Federal Aviation Administration also dealt with ground stops at Toronto Pearson International Airport on Tuesday. The weather pattern triggered flood warnings and tornado watches across parts of the Northeast, and weather and emergency officials said at least two tornadoes were spotted: one in northeast Pennsylvania and another in northern New Jersey.
Those conditions help explain why the same-day disruption spread across multiple major travel hubs rather than staying local. Airports in the New York City area, Boston, Philadelphia and Washington, D.C. took some of the most significant hits, and figures were expected to rise as the storms kept moving through the region.
