On July 28, 2026, nearly 1,000 flights were cancelled at John F. Kennedy International Airport, LaGuardia Airport, and Newark Liberty International Airport as severe thunderstorms and heavy rains caused major operational disruptions.
Heavy Rainfall and Flood Watches Across the Region
A Flood Watch was issued by the National Weather Service covering New York City, Long Island, the Hudson Valley, much of Connecticut, northern New Jersey, and eastern Pennsylvania. Several areas were forecast to receive 2 to 5 inches of rain, with isolated downpours possibly delivering 2 to 3 inches within a single hour. The Catskills region was expected to see between 6 to 8 inches of rain over
a few hours, increasing flash flood risks throughout the affected zones.
Storm System Background and Regional Flood Risk
The storms hitting the New York metropolitan area on July 28 originated from a weather system that previously triggered tornadoes, damaging winds, and hail across the Midwest earlier in the week. This prolonged rain event brought slow-moving thunderstorms that heightened flooding concerns in New York due to the region’s vulnerability, especially in the wake of the 2021 flooding caused by Hurricane Ida.
Impact on Air Travel and Road Safety
Flight operations were severely impacted with hundreds of cancellations reported at JFK, LaGuardia, and Newark airports throughout the storm. Travel warnings advised allowing extra time and avoiding
flooded roads as inundated streets, underpasses, and low-lying areas posed hazards for commuters. Authorities cautioned that further cancellations and delays could occur as the storm continued to move through the region.
Official Statements and Safety Advisories
Governor Kathy Hochul urged residents to monitor weather updates and refrain from driving through flooded areas. She stated, “New York State will be experiencing a prolonged rain event beginning Tuesday that will bring heavy rains and cause flash flooding,” adding, “When in doubt, turn around, don’t drown.” Mayor Zohran Mamdani emphasized preparation for dangerous weather conditions and possible flash flooding, while the New York City Emergency Management Department advised
allowing extra travel time and avoiding flood-prone routes.
