What EF3 means. On the Enhanced Fujita scale, EF3 is severe damage: whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, consistent with estimated gusts of 136–165 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

The tornado touched down northeast of Watson near the intersection of Little Woods Drive and Percy Easterly Road. It moved in a general easterly direction. It rapidly strengthened as it approached Nan Wesley Road, where it collapsed a metal truss tower holding up high tension power lines. In this area, the tornado is estimated to have reached its peak intensity of near 140 mph. It continued moving east, causing damage consistent with that of an EF-2 tornado, completely destroying three manufactured homes, and causing significant roof damage to two single family homes. It also snapped or uprooted numerous trees. The tornado continued moving east, causing damage primarily to the roofs of homes and trees. It lifted as it reached John Lanier Road.
