The tornado touched down in the vicinity of the Eagle Meadows 
Apartment Homes on Sorghum Mill Road in Kent County then moved 
across Route 10. It tracked nearly parallel to South State Street 
through Anneville, the south side of Dover, where significant tree
damage occurred, including some treetops shredded from Poplar 
Lane to the neighborhood around Steele Road. It was here where 
some roof damage occurred to some homes especially due to fallen 
trees, however a garage was significantly damaged on Dyer’s Tree
Farm. The tornado then crossed over Route 13 near the Eden 
Medical Center and very near the William Henry Middle School. A 
couple sections of the school’s roof were blown off along with 
some tree damage nearby. A warehouse adjacent to the school had a 
few sections of its metal walls torn off and a couple of tractor 
trailer trailers flipped onto their side. The tornado then crossed
over Walker Road at Route 15 then to Westminster Village at Dover
near the intersection of Route 15 and College Road.

The tornado then tracked northward just east of Cheswold where 
the damage may have been more sporadic before moving through the 
east side of Smyrna where more notable tree damage occurred. A 96 
mph wind gust was measured at a Delaware Department of 
Transportation weather station located on Route 1 just north of 
Smyrna as the tornadic circulation passed by. From here, the 
tornado continued nearly parallel to Routes 1 and 13 on the east 
sides of Townsend and Middletown in New Castle County. Numerous 
trees were snapped or uprooted along portions of Blackbird Landing
Road and Gum Bush Road in Townsend with some damage to roofs. A 
garage at a residence on Blackbird Landing Road was destroyed. The
tornado then damaged homes in Middletown along Spring Hollow 
Drive. In this neighborhood, some homes had roof material and 
siding blown off with numerous trees uprooted. Several garage 
doors were blown out. One home had an entire side wall blown out, 
although construction appeared to be poor. One picture showed a 
home with a missing exterior corner wall on the second story. 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. Doppler radar data 
showed a continuous and well defined rotational signature and a 
tornado debris signature.

Special thanks is extended to Kent County and New Castle County 
Emergency Management, trained spotters, and the public for their 
extensive assistance with this survey.

A waterspout came ashore near the southern end of Corson’s 
Inlet State Park near Strathmere then across marshy areas. The 
tornado then crossed the Garden State Parkway then tracked along 
Route 9 across the south side of Marmora. There were several 
pictures and videos of the waterspout and tornado including a 
trained spotter reporting a tornado on the ground with debris in 
the air. The tornado produced significant damage to homes and 
businesses on the 500 block of Route 9, starting in the vicinity 
of a Coca Cola facility where containers were tossed around with 
even a truck trailer flipped onto its side. Adjacent to the Coca 
Cola facility, a large shed at a residence was upended and 
vehicles were moved from their original locations. Several homes 
had portions of their roofs blown off with a couple of homes 
sustaining significant damage to a side wall or corner walls. The 
tornado crossed Route 9 to the Pine Hill Mobile Home Court where 
significant damage occurred to trees and buildings. One home was 
shifted off its foundation and others had roof damage and downed 
trees crushed several cars. The tornado tracked north northwest 
crossing Tuckahoe Road and may have dissipated over the adjacent 
marsh areas. Doppler radar data showed a well defined tornado 
debris signature as the tornado moved through portions of Marmora.

Special thanks is extended to Cape May County, trained spotters, 
and the local media for their help in this survey.

An EF0 tornado occurred in Worcester Township in Montgomery 
County, Pennsylvania as Tropical Storm Isaias moved northward 
along the East Coast of the United States. With southeastern 
Pennsylvania being in the northeastward, right front quadrant, the
tornado and parent storm moved in an unusual northwestward 
trajectory ahead of the main center of the tropical storm. An area
of circulation tightened in a strong cell within a rainband in 
southeastern Montgomery County. As this circulation tightened, a 
brief tornado formed near the intersection of Brindle Court and 
Township Line Road in Worcester Township, where a few small trees 
were downed in a small residential subdivision. From here, the 
tornado continued its northwestward trajectory through the 
township, downing trees along Potshop Road. The circulation may 
have lifted with the path being somewhat discontinuous. A somewhat
denser area of trees were downed as the tornado moved across 
Valley Forge Road and northwestward along Heebner Road. Several 
tree tops were sheared off in addition to several utility poles 
being pushed over along Heebner Road near the intersection of 
Shefley Lane. The tornado continued northwest from here, 
eventually downing several hardwood trees along Hollow Road. One 
tree brought down several utility lines as it fell. From here, the
tornado lifted with only a few other trees being downed a little 
ways from Hollow Road in a small wooded area. 
Special thanks is extended to the Montgomery County EM Office 
along with Skywarn Spotter Lou Ruh for their help in this survey.
