Survey Summary:
A brief tornado, associated with an outer rain band from Tropical
Storm Debby, moved onshore near 25th Ave where it did minor roof
damage to one house and also pulled the front door out the frame.
It continued north-northwest along 25th Ave, between Palm Blvd
and Hartnett Blvd it pulled out a few windows and snapped and
uprooted some trees. As it moved just north of Hartnett Blvd, it
removed the shingles from a portion of the roofs from a few
homes. Beyond this point, the tornado curved a bit more northwest
and snapped a few more trees and it began lifting near Waterway
Blvd and 24th Ave. The tornado continued northwest and dissipated
within the Intra Coastal Waterway. Overall, an estimated 29 homes
sustained some level of damage, either directly by the tornado or
from trees or large limbs falling on them.

The worst of the damage from #Debby on the Isle of Palms is located on 25th street, where Mayor Phillip Pounds says a water spout was around 1:30 am. Neighbors tell me they heard a loud noise, like a train, around that time. Luckily, no injuries reported. @Live5News pic.twitter.com/uU4oCQYHdM

Survey Summary:
The tornado, which originated in an outer rain band associated
with Tropical Storm Debby over the nearshore Atlantic waters,
moved onshore at Edisto Beach, near the intersection of Highway
174 and Palmetto Blvd. As the tornado moved onshore, it removed
roof decking, roof shingles and siding to several homes. The
Enmarket gas station also had some roof damage and air
conditioning units thrown from the roof. The tornado then moved
northwestward over a marsh region, snapping many hardwood trees
and uprooting numerous trees along Palmetto Road. From Palmetto
Road, the tornado continued on a northwest path crossing over
Fishing Creek Drive. At this location, the tornado did
considerable damage to several homes. It removed the entire roof
of at least three homes and part of the roof decking to at least
one more. The tornado was given its highest EF1 rating in this
area, with maximum winds estimated to be around 97 mph. Beyond
this location, the tornado continued northwest, dissipating over
the marsh region north of Palmetto Road. Note: there were likely
additional structures damaged along the path of the tornado, but
the amount of time to conduct the survey was limited.

Survey Summary:
A brief tornado, associated with an outer rain band from Tropical
Storm Debby, moved onshore at the south end of Edisto Island near
the 2700 block of Point Street, where it snapped and twisted some
small trees and removed asphalt shingles to at least one home.
The worst damage was on Palmetto Blvd, where one home had a
complete collapse of the porch and a significant portion of the
roof removed.  The tornado continued to move rapidly
northwestward crossing around the 2700 block of Myrtle Street,
where it did some minor damage to the facia of at least one home.
Just northwest, near the 2900 block of Lee Street, at least one
home had a corner of the roof removed. The tornado then moved
into the southern portion of the Plantation Golf Course where it
dissipated.

Survey Summary:
The tornado, which originated in an outer rain band associated
with Tropical Storm Debby, touched down just east of McCormick
Circle and snapped two trees in the woods just behind an
Applebees. The tornado then moved northwest, causing damage to
the Applebees sign, and then turned west and impacted the Arbys.
This was the location of the strongest damage as numerous windows
were blown out at the Arbys on both the west and east-facing
sides of the building. The rooftop A/C was also blown into the
Arbys parking lot. However, no other structural damage was
noted, and therefore the degree of damage was kept near the
middle of the expected wind speed, or at 95 mph. The Walmart
Supercenter to the northwest of Arbys also sustained some very
minor roof fascia damage, which was starting to peel off from the
main structure. After this, the tornado continued to move
northwest and passed Mitton Road, where several trees were
uprooted with a few branches greater than 3 inches diameter broken.
There was also a residence on Mitton Road that had roof damage to
less than 20% of the structure. The tornado then moved northwest
and weakened as it crossed Kitfield Rd, where some branches
(mostly 1 to 3 inches in diameter) were observed broken. To the
northwest on Lois Circle and Broughton Rd, branches that were
snapped (1 to 3 inches in diameter) were noted. Finally, the tornado
moved to the northwest, and dissipated on the northern end of the
Pinopolis peninsula on the south end of Lake Moultrie.

The National Weather Service at Charleston, SC would like to thank
Berkeley County Emergency Management for their invaluable help
with various damage photos and track maps.
