EF0 tornado, Belton to Temple, Texas, April 10, 2008

From Belton to Temple, this EF0 tornado ran 6.4 miles across Bell County on April 10, 2008, touching down at 4:05 AM CDT and reaching 100 yards wide. It killed nobody, and did $500,000 of property damage.

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 mphthis tornado

    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.

  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

Several rounds of storms moved across north Texas on April 8th through 10th. Numerous reports of large hail were received on Tuesday evening. A lone supercell evolved during the afternoon hours of the 9th, producing tornadoes and large hail along its path. Later that evening and into Thursday morning a squall line tracked across north Texas, producing damaging winds and tornadoes into the morning hours.

In Belton, amateur radio operators reported power flashes and a few downed trees. In and around Temple, power flashes were reported and numerous roofs, fences, and signs were damaged. One fence which was knocked down was anchored with cement pillars. Guests at a motel which lost a roof were temporarily trapped in their rooms due to their doors being barracaded by debris. Vehicles were damaged by tree limbs and other debris. A duplex also lost a roof and suffered water damage. A golf course lost its scoreboard which was supported by several 4-inch metal poles. An estimated forty trees were uprooted or damaged.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

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 General Thunderstorms Risk. The outlook in force was issued at 06:01 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.
