Survey Summary:
A National Weather Service Storm Survey team confirmed an
EF1 tornado in Clarendon County that occurred within a wide swath
of damaging winds, extending from Swansea to Lake Marion. Based
on ground observations and radar, the tornado likely developed
over Lake Marion, just east of Lone Star before emerging over
land near Hickory Top Road. The tornado snapped numerous limbs
and large branches along Old River Road as it moved southeast.
The tornado strengthened and caused substantial tree and power
line damage near Old River Road and Clifton Road and then further
east near Liberty Hill Road and Rapid Edge Trail. Moving
southeast, minor tree damage occurred across Highway 15 and I95.
Numerous trees were then uprooted along MG Hemingway Road. The
tornado slowly weakened causing minor damage across Washington
Davis Road before dissipating near Bill Davis Road.
