F2 tornado, Stiles to St Lawrence, Texas, March 22, 2000

From Stiles to St Lawrence, this F2 tornado ran 12.0 miles across Reagan and Glasscock counties on March 22, 2000, touching down at 10:55 PM CST and reaching 300 yards wide. It killed nobody and injured 5, and did $240,000 of property damage.

The rating scale

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

  1. F040 to 72 mph

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

  2. F173 to 112 mph

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

  3. F2113 to 157 mphthis tornado

    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. F3158 to 206 mph

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

  5. F4207 to 260 mph

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

  6. F5261 to 318 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.

  7. Unrated

    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

This storm was a classic supercell that formed ahead of the training line of storms to the west.

The tornado knocked a small house off its foundation by about 15 yards with the house pivoting 90 degrees as well. One infant suffered a slight head injury from falling furniture. The tornado continued travelling north-northeast through rural areas, but struck and destroyed a mobile home, injuring two men, one seriously. Lighter damage was scattered along the rest of its path, including utility poles down, parts of roofs damaged, fences and barns damaged, etc. The tornado crossed into Glasscock County at 31.65N/101.50W.

Tornado continued from northern Reagan County. A string of 12 utility poles was knocked down on FM 2401, an abandoned house lost part of its roof, and 6 more poles were knocked down on Ranch Road 33. The tornado apparently dissipated just after knocking down the last set of poles. The entire path length of the tornado was 12 miles.

The warnings

38 minutes of warning. NWS MAF issued a tornado warning for this county at 04:17 UTC, 38 minutes before the tornado touched down, in force until 05:00 UTC.

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 Moderate Risk. The outlook in force was issued at 00:33 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.
