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

Storm survey confirmed EF-1 tornado with max winds of 105 mph began just north of Port Lavaca and continued southeast. Damage to several structures as well as widespread tree damage was notes. Some trees uprooted.

The wider storm

Severe storms spread across South Texas from the Hill Country as a mid-level shortwave replaced a northward lifting warm front over the region. Significant instability, strong DCAPE, and strong shear over 50 knots set up a favorable environment for strong to severe storms with large hail and damaging winds the primary threats. Supercells developed widespread across the area, with large hail reported over the Coastal Plains and Brush Country, an EF-1 tornado was observed in east Calhoun causing damage to several structures and trees. Severe winds also caused significant damage to an RV park south of Port Lavaca, resulting in 2 injuries and at least 12 RVs damaged or completely destroyed.

Began near Port Lavaca Arpt (28.6800, -96.6600).
