EF1 tornado, Union Hill, Louisiana, May 30, 2024

This EF1 tornado ran 4.1 miles across Rapides Parish on May 30, 2024, touching down at 9:16 PM CDT and reaching 50 yards wide. It killed nobody, and did $20,000 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

26 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 100 mph.

  • Pine tree branches snapped.
  • Aluminum roof of single wide manufactured home peeled back but not removed.
  • Partial removal of aluminum roof of mobile home.
  • Trunk of softwood tree snapped. Tree fell to south?

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

Short waves traversed the region during the afternoons at the end of May. This occurred while the area was at peak afternoon heating each day which set the stage for severe thunderstorms to develop.

The tornado began just west of Highway 462 and north of Jim Thompson Road near Westport. The tornado produced scattered tree damage before crossing Freedom Road. It travelled across a forested area before crossing Doshie Road where more trees were snapped and uprooted. From there the tornado travelled northwest crossing Mitch Johnson road and Highway 112. The tornado snapped and uprooted several trees along Hwy 112. One of these trees fell on the roof of a single family home. The tornado then continued into a forested area east of Highway 112 where it dissipated.

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

The warnings

4 minutes of warning. NWS LCH issued a tornado warning for this county at 02:12 UTC, 4 minutes before the tornado touched down, in force until 02:45 UTC.

The county was under a severe thunderstorm watch, issued at 01:53 UTC and running to 03:52 UTC.

The forecast that day

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 00:51 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.
