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

This tornado formed approximately six miles west of Truscott and initially moved just north of due east with occasional damage to mesquite trees. As it approached County Road 2610 and FM 1756 a semi truck was knocked over, and a 4000 pound cattle feeder was blown about 850 feet to the north-northeast. Two structures on the southeast side of Truscott-Brine Lake received roof and window damage. Utility poles were broken from the area just southeast of Truscott-Brine Lake to State Highway 6, including steel utility poles that were bent. The tornado weakened and then dissipated after crossing Highway 6.
