Unrated tornado, Vigo Park, Texas, May 28, 2023

This Unrated tornado ran 0.4 miles across Swisher County on May 28, 2023, touching down at 5:09 PM CDT and reaching 30 yards wide. It killed nobody.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mph

    Considerable damage. Roofs torn off well-built houses, frame homes shifted on their foundations, mobile homes destroyed, large trees snapped or uprooted, cars lifted off the ground.

  4. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 mph

    Incredible damage. Strong frame houses swept off their foundations, car-sized missiles thrown more than 100 meters, steel-reinforced concrete badly damaged, high-rise buildings deformed.

    The survey recorded a tornado but could not put a number on it, most often because it crossed open country and damaged nothing a rating can be read from.

What the Weather Service recorded

Scattered supercell thunderstorms developed on the afternoon of the 28th and persisted through the evening producing several severe storms despite weak background forcing. Strong instability developed while the atmosphere became uncapped which allowed these supercell thunderstorms to develop. A slow moving storm near Vigo Park produced a brief tornado over an open field. More widespread thunderstorms evolved late in the evening while tracking from west to east over much of the South Plains and Rolling Plains. In Lubbock, a tree hit by lightning fell on a vehicle. These widespread slow moving storms produced extensive flash flooding especially over Lubbock County. Several roads were closed due to flooding with numerous stranded vehicles. After the cluster of thunderstorms moved east of Lubbock, a heat burst was observed at Reese Center (Lubbock County) within a stratiform region. A peak wind gust of 67 mph was observed with this heat burst as well as a 15 degree temperature increase.

A video shared on social media showed a brief tornado southwest of Vigo Park in an open field. No damage was known to have occurred.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

The forecast that day

The Storm Prediction Center had this point in a Marginal Risk. The outlook in force was issued at 19:50 UTC.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. Tornado counts rise through the record as reporting improved, so a year in the 1950s is not comparable with one today except for the strongest tornadoes, which were always noticed.
