EF0 tornado, Theodore Idle Hour A to Laurendine, Alabama, March 11, 2026

From Theodore Idle Hour A to Laurendine, this EF0 tornado ran 1.1 miles across Mobile County on March 11, 2026, touching down at 12:20 AM CDT and reaching 200 yards wide. It killed nobody.

Preliminary. This is NWS MOB's damage survey, filed in the Damage Assessment Toolkit as Dees. 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 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 survey found

Available high resolution satellite imagery revealed a brief EF0 tornado tracked along Dawes Road just northeast of Dees. The tornado remained primarily within forest causing minor tree damage along its track. The track of the tornado is also supported by a radar tornado debris signature.

Written by NWS MOB in the NWS Damage Assessment Toolkit. A survey is revised as better evidence arrives.

The damage survey

21 damage points were recorded along this path by NWS MOB, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

  • Minor tree damage visible on satellite imagery collocated with radar TDS.
  • Minor tree damage visible at this location collocated with a weak radar TDS.
  • Radar TDS, minor tree damage at this location visible via satellite imagery.
  • Minor tree damage visible at this location via high resolution satellite imagery.

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

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.

Available high resolution satellite imagery revealed a brief|EF0 tornado tracked along Dawes Road just northeast of Dees. The|tornado remained primarily within forest causing minor tree|damage along its track. The track of the tornado is also|supported by a radar tornado debris signature.

Available high resolution satellite imagery was able to reveal an|EF0 tornado tracked north of Interstate 10 near Grand Bay. The|tornado began north of Pascagoula Road solely in forest causing|minor tree damage. While there is a gap in visible damage on|satellite imagery, radar tornado debris signature persists east|connecting with another small corridor of tree damage near Ramsey|Road and Boe Road. This is where the end point of the tornado is|estimated as any visible damage associated with the radar|signature disappears after reaching I-10.

Available high resolution satellite imagery revealed a weak|EF0 tornado tracked from Irvington through the Laurendine area|causing sporadic minor tree damage all along its track. The track|of the tornado is further supported by the presence of a radar|tornado debris signature.

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.
