Tropical Storm Isaias produced an EF-1 tornado with winds at 105 mph. Officials say the tornado touched down in the vicinity of the Eagle Meadows Apartment Homes on Sorghum Mill Road in Kent County and stayed on the ground for 29.2 miles. That's the longest track of any tornado in recorded history in the Philadelphia region since the 1950s.
The Delaware tornado was also tracked over Dover, where significant tree damage occurred, and later damaged homes in Middletown, New Castle County.
"The tornado may have started to dissipate between Mount Pleasant and Glasgow in New Castle County, however it is possible the tornado track extended into Cecil County, Maryland," said the NWS.
