EF1 tornado, Isney to Souwilpa, Alabama, March 11, 2026

From Isney to Souwilpa, this EF1 tornado ran 1.5 miles across Choctaw County on March 11, 2026, touching down at 10:28 PM CDT and reaching 230 yards wide. It killed nobody.

Preliminary. This is NWS MOB's damage survey, filed in the Damage Assessment Toolkit as Isney. The rating, the path and the casualties are the survey's and can change while it is revised. The Storm Prediction Center compiles the official record of 2026 from these surveys and publishes it in the spring of 2027; this page moves to that tornado's permanent address when it does.

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.

What the survey found

The EF-1 tornado began just west of Wildflower Rd south of highway 84 near Isney Alabama. The tornado resulted in a few uprooted and snapped trees as it passed over Wildflower Rd. The tornado reached its peak intensity likely between Wildflower Rd and Poultry Rd where it snapped several softwoods, uprooted other trees and did damage to several chicken farm buildings. Total damage to the chicken farm was difficult to determine given the buildings were already damaged from a prior storm but satellite imagery was able to assist in determining there was at least some new damage to the buildings. As a result peak intensity was given to the tree damage and a lower bound estimate was given to the chicken farm. The tornado then proceeded towards highway 84 as it slowly weakened before crossing highway 84 near Lone Star Rd.

The damage survey

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

  • Shed attached to building, pulled towards dead pecan. Likely edge of tornado
  • Minor loss of roof panels via sentinel 2 satellite imagery. Was able to confirm this visually from the adjacent highway 84, but were unable to get closer due to the road being blocked by downed trees.
  • Most trees along this tree line were substantially damaged adjacent to the lake, with multiple snaps and uproots likely visible via Sentinel 2 satellite imagery. This was likely the tornadoes strongest point in comparison to other ground surveyed points.
  • Several mid-trunk snaps visible from the road via ground survey crew off Highway 84.

What the Weather Service recorded

A strong cold front moved across the area with a line of showers and thunderstorms. The storms produced several tornadoes and gusty winds across southwest Alabama.

A|large oak was uprooted before the short tornado dissipated into|the woods. Peak intensity was likely around 90 mph based on the|uproots and snapped trunks.

The brief EF-1 tornado began along Souwilpa road near Alabama|Highway 187 where it uprooted and snapped a couple of trees. A|very narrow convergence path was noted as it crossed highway|17 peaking in intensity as it snapped a few small softwood pines|before likely dissipating in the woods east of highway 17.

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.

The county was under a tornado watch, issued at 23:56 UTC and running to 05:04 UTC.

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, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 00:54 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

What this means

Ratings are the survey's, read off the damage rather than measured; the rating scale is above. A survey can be revised, so the rating, the path and the casualties can all still change.
