Severe thunderstorms produced confirmed tornadoes in Delaware and New Jersey on Thursday as a powerful nor'easter moved through the Northeast and Mid-Atlantic.

The National Weather Service confirmed a tornado touched down in New Castle County, Delaware, near Christiana Hospital in Wilmington. Another tornado was confirmed in Burlington County, New Jersey. These marked rare November events for the area, with Delaware recording only its second such tornado since 1950.

A tornado warning was issued for parts of Queens, New York, near JFK International Airport after radar detected rotation in a storm moving toward the facility. Both JFK and LaGuardia airports implemented ground stops amid the activity.

The storms also brought large hail, damaging winds, flash flooding, and power outages across the Delaware Valley and surrounding areas. Hail up to 1.75 inches fell in parts of the region, closing roads in some Pennsylvania suburbs. More than 1,300 customers lost power in Burlington County, New Jersey.

Forecasters noted the unusual timing for such severe weather in mid-November. A tornado watch covered portions of Pennsylvania, New Jersey, and Delaware through Thursday evening.

Cleanup efforts began immediately in affected areas, with officials urging residents to avoid downed power lines and flooded roadways. Temperatures dropped sharply overnight into the 40s with gusty winds, and colder conditions are expected to persist.

Additional tornado reports from earlier in the month involved remnants of Tropical Storm Isaias in North Carolina, where the total confirmed touchdowns reached 14 after a late survey near Raleigh-Durham International Airport.
