Severe storms disrupt New York-area flights as flooding hits roads
Severe thunderstorms and heavy rain disrupted air and ground travel across the New York metropolitan area on Thursday, August 27, as flash-flood concerns spread across New York City and nearby parts of New York and New Jersey.
LaGuardia Airport had nearly 100 cancellations and more than 200 delays during the storm, according to ABC7 New York. Newark reported delays of up to two hours as storms moved through the region. The disruption did not mean every flight at LaGuardia, John F. Kennedy International Airport or Newark was affected; conditions varied by airport, route, airline and time.
FAA showed lighter general delays Friday morning
The Federal Aviation Administration’s National Airspace System status page was last updated Friday, August 28, 2026, at 11:14:16 GMT. At that update, it listed no active national ground-stop program, airport closure or delay notice.
The FAA’s Northeastern States airport-status page listed general arrival and departure delays of 15 minutes or less at Newark, JFK and LaGuardia. That is a broad operating snapshot, not a flight-by-flight determination. The FAA says travelers should check with their airline to determine whether a particular flight is affected.
A ground stop or ground-delay program also would not necessarily mean an airport had closed. Such measures manage traffic entering or leaving an airport and can change as weather and air-traffic conditions develop.
Flooding slowed road travel
Heavy rain also affected roads in New York City and New Jersey. ABC7 reported flooding from the Major Deegan Expressway in the Bronx to Staten Island and parts of New Jersey.
In Keyport, New Jersey, flooding led to multiple street closures. Old Bridge officials warned residents about flooded roads, and police in Sayreville said stalled vehicles were blocking roadways.
Those reports identify documented trouble spots, not a complete inventory of road conditions across the metro area. Drivers should check local transportation and emergency alerts before leaving and should never attempt to cross standing or moving floodwater.
Why the storms caused disruptions
The National Weather Service issued Severe Thunderstorm Watch 630 for Thursday afternoon and evening, covering New York City and several nearby New York counties. A flood watch also covered portions of southern Connecticut, northeast New Jersey and southeast New York. NWS products warned that intense rain could overwhelm urban, low-lying and poorly drained areas.
Forecast guidance cited by local weather coverage called for rainfall rates of 2 inches or more per hour in the strongest downpours. Most of the region was expected to receive less than 2 inches of rain, while localized areas could see substantially higher totals. Those conditions can quickly affect runways, air-traffic flows, highways and surface streets at the same time.
By early Friday, the NWS New York office was highlighting patchy dense fog through 10 a.m. in New York City, Long Island, parts of the Lower Hudson Valley and southern Connecticut. The statement warned that visibility could fall below one mile, with locally denser fog during the morning commute.
What travelers should do Friday
Check the airline app or website immediately before leaving for the airport and again during the trip. Build extra time into the drive or transit trip because flooded roads, stalled vehicles, dense fog and reduced visibility can create delays even when a flight remains scheduled.
If a flight is canceled or substantially delayed, ask the airline about rebooking options, refunds where applicable and any weather waiver attached to the ticket. Nearby airports can also be affected because JFK, LaGuardia and Newark share constrained regional airspace, but travelers should not assume that a disruption at one airport automatically applies to another.
Watch for additional National Weather Service statements and local road-closure notices. The FAA’s status pages can help explain broad operating conditions, but the airline remains the source for a traveler’s specific cancellation, delay, rebooking or waiver information.
