The path drawn at its surveyed width of 30 yards (0.02 mi) — zoom in and the swath grows to true scale. Other tornadoes recorded nearby that day are shown faint.

What EF0 means. On the Enhanced Fujita scale, EF0 is light damage: shingles and siding peeled, gutters torn, branches broken, consistent with estimated gusts of 65–85 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

Tornado touched down on Belaire Drive removing the roof from one home with debris blown into another home across the street. Several power poles were snapped.

The wider storm

During the early evening hours on March 28th, isolated severe thunderstorms developed across northern Mexico and Deep South Texas. Storms formed within an environment of very unstable air and very strong vertical wind shear in advance of an approaching cold front with assistance from an approaching upper level disturbance. Severe storms occurred across the Brush Country during the evening. The storms congealed into a squall line late in the evening. Large hail and winds of at least 60 mph were observed with several of these storms across the Brush Country. During the early morning hours on March 29th, the squall line intensified as it advanced into the Coastal Bend and the Victoria area. Widespread winds between 40 and 60 mph were observed behind the squall line during this time. Sufficient low level shear in the lowest several thousand feet existed to produce mesovortices along the squall line. Several of these mesovortices produced tornadoes across the Coastal Bend during the early morning hours.

Began near Holiday Beach (28.1670, -97.0177).
