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

NWS storm survey found that an EF1 tornado that began just southeast of Blacksburg in Cherokee County crossed into York County in Kings Mountain National Military Park crossing Piedmont Rd and Park Rd before moving out of the park in the area around Highway 161 N and Whitworth Rd. The tornado weakened around this point, but additional damage was found around Henry Knob Rd and Grandview Rd N where the tornado appeared to lift. Numerous trees were snapped and uprooted along the path in York County but structural damage was minimal in this largely rural area.

The wider storm

A line of thunderstorms moved into upstate South Carolina from northeast Georgia during the early afternoon and quickly intensified. Multiple reports of locally damaging wind gusts were received, and a weak tornado moved across Kings Mountain State Park and vicinity.

Began near Kings Creek (35.1360, -81.4010).
