Tornado in HORRY, SOUTH CAROLINA
From 17-DEC-23 13:16:00 to 17-DEC-23 13:20:00 (EST-5)
Location: STALVEY
Tornado F-scale: EF1
Property damage: 200.00K
Crop damage: 0.00K
Reported by: NWS Storm Survey

The tornado touched down south of Socastee Blvd between Everette
St and Tyner St, snapping several large trees and blowing off
portions of roofs from a few mobile homes. It moved north,
skipped across Socastee Blvd, and snapped several large pines
along Village Dr. Eight homes suffered moderate to major damage
as a result of falling trees. The storm cell continued north
across inaccessible property, and emerged near Folly Rd and
Wayland Circle. Significant damage was observed to several homes
and trees. Several trees were snapped or uprooted, and minor to
moderate damage was noted to roofs and siding. One mobile home
was pushed off its block foundation. The tornado appeared to lift
as it crossed the Intracoastal Waterway and touched down again on
the Arrowhead Country Club property. Numerous large hard and
softwood trees were snapped just south of the Flintlake
Apartments. Tree debris was blown into several apartments,
breaking windows and causing moderate roof and siding damage.
Damage upstream of the initial touchdown, along and south of
Palmetto Pointe Blvd, was straightline in nature and not the
result of a tornado. Additional wind damage occurred to the old
Waccamaw Mall at Fantasy Harbour. Portions of the facade were
blown off, in addition to several pieces of siding. A few bay
doors were blown in, and a large section of storefront wall was
buckled outward a few inches. A few nearby UPS and FedEx trucks
were blown over, in addition to a tractor trailer. This damage
appeared to be the result of straightline winds that occurred
after the tornado dissipated and the storm cell bowed
northeastward. Spotty tree damage was also observed on the
northeast side of Highway 501 in the River Oaks area.
