The National Weather Service issued a tornado warning Thursday afternoon for parts of southern Queens, including the area around John F. Kennedy International Airport, and southwestern Nassau County.

The warning, effective from 1:14 p.m. to 2 p.m. Eastern time, covered a storm with radar-indicated rotation near Rockaway Beach that moved northeast at about 15 miles per hour toward the airport.

No tornado was confirmed in the New York City area from the event. The alert affected roughly 144,500 people and included risks of quarter-sized hail.

Both JFK and LaGuardia airports implemented ground stops as thunderstorms and hail passed through the region. Heavy rain caused flash flooding, including closures on parts of the JFK Expressway and reports of vehicles stuck in high water nearby.

The warning came as a powerful storm system brought an unusual mix of severe weather to the Northeast and Mid-Atlantic on Thursday. Forecasters noted that organized severe thunderstorms are uncommon this late in the year in the region, with most such activity occurring between April and September. It marked the first time in five years the New York metro area experienced this level of severe storm activity during November.

New York City Emergency Management advised residents in the warned areas to take shelter immediately in a basement or small interior room on the lowest floor, away from windows. The agency encouraged signing up for emergency alerts by texting NOTIFYNYC to 692-692.

Similar tornado warnings were issued elsewhere in the region, including parts of Delaware, where reports indicated probable tornado damage. Tornado watches covered areas of Pennsylvania and New Jersey through Thursday evening before being canceled later in the day.

The storms also produced large hail and damaging winds across multiple states, with nearly 50 storm reports recorded from Delaware to New York. JFK Airport recorded more than 3.3 inches of rain, marking one of its wettest November days on record.

No severe storms were expected in the area on Friday or Saturday.
