EF1 tornado, Liberty to Gillisburg, Mississippi, June 4, 2024

From Liberty to Gillisburg, this EF1 tornado ran 4.2 miles across Amite County on June 4, 2024, touching down at 4:36 PM CDT and reaching 200 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 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

44 damage points were recorded along this path by NWS LIX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EFU. The highest wind the damage implies is 100 mph.

  • Convergent into further north points along same road
  • Convergent to the northeast
  • Laying due north into circulation
  • Two snapped pines laying to the NE

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

The start of what would eventually be a very potent Mesoscale Convective System (MCS) began around midnight on June 4th in central Oklahoma. A cluster of thunderstorms became outflow dominant with the convection chasing the outflow boundary southeastward. The MCS had weakened quite a bit as it moved into northwest Louisiana. However, strong daytime heating and pooling moisture ahead of this was waiting for it in southern Mississippi. Those warm temps and high dewpoints increased surface and mid level instability that would support very strong updrafts. Although shear was relatively low, it was sufficient to support severe weather. About the time the MCS reached the Mississippi River, it began to rapidly intensify into a well organized system. As it moved through the area, it produced wide spread wind damage and four tornadoes. No injuries or fatalities reported with these tornadoes.

An EF-1 tornado embedded in a QLCS formed along Enterprise Rd west of Liberty where a large pine tree was snapped. This tornado then moved eastward towards Toler Ln where it peaked in intensity. Here, a swath of at least 20 pine trees were snapped clean near the base. This tornado then weakened as it moved east over highway 567 where only limbs were noted. The tornado came to the end of its lifecycle near McLain and Meadville Rd where it uprooted more pines and broke off large limbs. Peak winds were 100 mph.

This EF-1 tornado embedded in a QLCS formed along Highway 24 east of Liberty. Here, large limbs were broken off an oak tree. The tornado moved to the east-southeast towards Patterson Rd where small limbs were broken and uprooted trees were noted. This tornado strengthened to peak intensity of 100 mph as it moved into a patch of trees just west and on Peoria Rd. Here, large swaths of trees were either snapped or uprooted in a convergent pattern. A tree fell on a home here, but no one was injured. This tornado then paralleled Turner Rd to the south where it continued to snap and uproot pines. Damage from where a mobile home used to be was noted, but it's unclear whether it was from the storm. This tornado continued to the east-southeast before lifting soon after snapping a tree along Lower Glading Rd.

An EF-1 tornado embedded in a QLCS started just north of the Louisiana/Mississippi State line in Gillsburg. It uprooted and snapped hardwoods along Travis Rd and Highway 568. The tornado traveled eastward, snapping and uprooting many trees along Highway 571 and 584. The tornado exited Amite County near where Trinity Creek enters into Pike County. Peak winds were 95 mph.

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.
