The Federal Aviation Administration (FAA) issued ground stops at LaGuardia Airport and nine other U.S. airports on September 3, 2026, halting all departures amid severe thunderstorms disrupting the Northeast corridor. Ground stops, a more restrictive measure than ground delays, prevent aircraft from leaving the gate and were used as storms caused widespread air traffic flow restrictions.
Delays at Major Airports Reach Two Hours or More
LaGuardia Airport recorded average ground delays of 45 minutes during the thunderstorm activity. Newark Liberty International Airport experienced peak delays averaging two hours. Boston Logan International Airport reported 19 delays, the highest thunderstorm-related total among U.S. airports that day. Ground-delay programs also remained active
at Newark, JFK, and LaGuardia to manage arrivals and departures amid ongoing weather disruptions.
Three Consecutive Days of Severe Thunderstorms Impact Northeast
Persistent severe thunderstorms affected the Northeast and Mid-Atlantic region for three consecutive days from September 1 through September 3. The storms caused air traffic restrictions across the tri-state area—encompassing New York, New Jersey, and Connecticut—as well as in Boston, Philadelphia, and Washington. These localized meteorological events generated cascading delays throughout the airspace network serving the Northeast corridor.
Labor Day Travel Faces Disruptions; Airlines Issue Waivers
The weather-related ground stops and delays occurred during the Labor Day weekend, traditionally one of the nation’s busiest travel periods. Major airlines issued travel waivers allowing passengers to reschedule
flights without change fees. The FAA’s National Airspace System Status page reported the air traffic network operating with minimal reserves due to cumulative disruptions, including cascading cancellations and delays.
Recent Weather Patterns Compound Northeast Flight Disruptions
Severe thunderstorms disrupting flights in early September followed Tropical Storm Edouard, which struck Louisiana in late August with sustained winds of 60 mph. Ground stops issued as a safety measure occur when the FAA Command Center lacks sufficient data to manage full delay programs. The combination of ground stops at major hubs including LaGuardia, Newark, and JFK creates cascading operational impacts on crews and aircraft, prolonging delays even after storms subside.
