The path drawn at its surveyed width of 150 yards (0.09 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

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

A tornado first touched ground near the Beyer Feed Store on the north side of Fredericksburg on Hwy 16. It moved northeast and caused tree damage and took down a power line off Knopp School Rd. and Quail Run Dr. From aerial images, there is significant tree damage in about a 150 yard wide path extending to Koennecke-Eckhardt Rd. The tornado continued moving northeast where it crossed Herber-Schaefer Rd. There was tree and roof damage at a residence on FM 1631. The tornado dissipated a short time later as it crossed Wahrmund-Ahrens Rd. The highest estimated wind speed was 100 mph and it was rated EF-1.

The wider storm

An upper level shortwave trough moved around a low over the southwestern US and enhanced lift over the mountains in northern Mexico and a dryline in West Texas. These features interacted with a warm, moist airmass over South Central Texas to generate thunderstorms. Some of these storms produced tornadoes and large hail. The large hail that hit the City of Del Rio and near Brackettville likely caused in excess of 10 million dollars in damage but as of this writing do not have an accurate estimate of damage from city/county/state officials or private insurance companies.

Began near Fredericksburg (30.3007, -98.8248).
