EF1 tornado, Mt Union to Belgrade, Texas, April 24, 2015

From Mt Union to Belgrade, this EF1 tornado ran 13.3 miles across Jasper and Newton counties on April 24, 2015, touching down at 11:58 AM CDT and reaching 50 yards wide. It killed nobody, and did $75,000 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 mph

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

  2. EF186 to 110 mphthis tornado

    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.

The damage survey

2 damage points were recorded along this path by NWS LCH, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 104 mph.

What the Weather Service recorded

A large upper level trough stalled over the southwest states while multiple short waves rotated around the larger trough over a few days. This produced several rounds of severe weather with tornadoes, hail, and high winds reported. The first round entered the region by late morning on the 24th as a long lived super cell tracked from Tyler County into Louisiana and then into the gulf. The second round of severe weather produced one report of wind damage while the 3rd and 4th rounds produced widespread wind damage, a tornado, and copious amounts of hail.

An EF1 tornado originated near the Neches River west of Kirbyville and moved east to southeast crossing Highway 82 west of Kirbyville near the airport. The tornado continued into Newton County between FM 1013 and South Saint Aubin Road. Numerous trees were uprooted or snapped along the path damaging a few homes from debris hitting them. Some outbuildings were also damaged. The average width was 50 yards and the path was 8.27 miles long in Jasper County. The total length of the path was 13.3 miles.

This tornado formed near the Neches River west of Kirbyville in Jasper County and moved east to southeast. The tornado entered Newton County between FM 1013 and South Saint Aubin Road as it passed north of Call. Numerous trees were uprooted or snapped along the path damaging a few homes from debris hitting them. Some outbuildings were also damaged. The average width was 50 yards and the path was 5 miles long in Newton County. The total length of the path was 13.3 miles.

An EF1 tornado began Southeast of Call and moved across mostly forest. The tornado snapped or uprooted many trees along its path before crossing the Sabine River and moving into Beauregard Parish west of Bancroft. The tornado crossed the Sabine River near the east end of Magnum Road. The tornado path in Newton county was 3.94 miles long and 50 yards wide.

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.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 16:32 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.
