What EF1 means. On the Enhanced Fujita scale, EF1 is moderate damage: roofs badly stripped, mobile homes pushed off foundations or overturned, windows broken, consistent with estimated gusts of 86–110 mph. The rating comes from a survey of the worst damage after the storm, not from a wind measurement, so it says as much about what the tornado hit as about how strong it was.

What the National Weather Service wrote

An EF-1 tornado touched down in Orangeburg Co SC around 1401 EDT (1301 EST) near the intersection of Old Elloree Rd and Odell Dr. The tornado then moved quickly to the north-northeast for nearly 8 miles, moving into Calhoun Co SC around 1407 EDT (1307 EST) near Church Camp Rd and Moorer Rd. The tornado continued to the NNE crossing Belleville Rd and then lifted around 1409 EDT (1309 EST) before reaching US Hwy 176.

The tornado did considerable damage, snapping and uprooting a large number of hardwood and softwood trees along its path. Walls collapsed on a cinder block garage, with the metal roofing tossed across the roadway, on Moorer Rd.

The wider storm

Moderate to strong atmospheric instability and shear led to a line of showers and thunderstorms along a cold front, that moved east across the region during the afternoon, producing wind damage along with some embedded tornadoes.

NWS Storm Survey teams found that a total of 5 tornadoes occurred. Considerable thunderstorm downburst wind damage also occurred. A 3-year-old boy was killed when a large tree, that was downed by strong thunderstorm winds, fell onto his home near Sumter, SC.

Began near Cameron (33.5730, -80.7630).
