Thunderstorm Wind — Marlboro, South Carolina

2020-04-13 · near Wallace, Marlboro, South Carolina

Event narrative

A few very strong microburts caused widespread damage near the city of

Wallace SC. The width of the entire damage area is approximately 2 to 3

miles wide and 4 to 5 miles long. All of the damage was aligned nearly

unidirectional at every location damage was observed. The near straight

line swath of damage coupled with evidence of a very wide swath of damage

was indicative of microbursts in this event.

Most of the winds within this area ranged from 65 to 85 mph with several

locations of 90 to 110 mph winds. Several homes were impacted with roofs

blown off, and an unanchored single wide mobile home was flipped off its

foundation. In addition, hundreds of softwood and hardwood trees

were either snapped or uprooted across a wide area. The most intensive

damage appeared in three areas including: Grants Mill Rd W near Hwy 9

east of Wallace, the Garden Rd area near Old Wire Rd., and along sections

of Hwy 177 northeast of Wallace.
