The National Weather Service in Mount Holly NJ has confirmed a tornado near Greenwood in Sussex County Delaware on June 19, 2017.

A path of straight-line winds started in a wooded area near the intersection of Adams Road and 583A, which is behind the Delaware Electric Coop facility. Several trees were snapped and uprooted, then the south end of a warehouse at the Delaware Electric Coop was pushed in with two large garage doors blown out. A section of the roof was also significantly damaged. Security camera footage showed very strong winds moving through the Delaware Electric Coop, however there was no clear evidence of a tornado. This narrow but intense downburst continued east-northeast and caused areas of tree damage. The straight-line winds were estimated to be between 75-80 mph.

Radar data, which was very close by, indicated a rotation signature which intensified for a time as an outflow boundary settled southeastward and interacted with this storm. The radar was scanning within 600 feet above ground level, with even evidence of a tornado debris signature in the dual-pol data. A
tornado touched down between Nanticoke River and the intersection of Sugar Hill Road and St. Johnstown Road, and tracked northeastward for about 0.6 miles before lifting. There was significant damage to a farm, with a couple of small barns destroyed with a lot of debris lofted and blown far across an adjacent field. Several trees were snapped or blown over along with damage to a few nearby power poles and wires. A large unoccupied chicken coup, about 200 feet in length, was lifted and moved several feet off its foundation with some metal roof panels on the north end were twisted in a southerly direction. Across the street from the farm on Sugar Hill Road, a couple sections of large central pivot irrigation systems were lifted and tipped onto their side. Each section of the irrigation weighs about 8800 pounds.

As the storm moved east-northeast to the Lincoln and Ellendale areas, some sporadic areas of straight-line wind damage occurred mostly to large trees. Some of the trees were snapped toward the
top, while areas between the farm and Ellendale had trees uprooted or snapped.

The National Weather Service would like to thank the Delaware Emergency Management Agency, Sussex County Emergency Management, Delaware Electric Coop and residents of Greenwood for their
assistance in this survey.
