EF0 tornado, Dixie Spgs, Alabama, November 30, 2022

This EF0 tornado ran 2.0 miles across Walker County on November 30, 2022, touching down at 12:28 AM CST and reaching 50 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 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.

The damage survey

3 damage points were recorded along this path by NWS BMX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 73 mph.

  • 5 trees blown down at this location facing the northeast
  • Estimated start point via RADAR which showed both a TVS and subsequent TDS. Inaccessible area.
  • Two pine trunks snapped at top of hill visible from Tutwiler Rd.

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 very dynamic and deepening low pressure system moved through the Ohio Valley states on November 29-30 with a trailing cold. The air mass across Central Alabama was initially stable during the day on November 29th with surface dewpoints in the 40s and 50s. Instability increased dramatically the evening of the 29th as 60 plus surface dewpoints advected northward into Central Alabama. A QLCS developed ahead of the approaching cold front in addition to discrete thunderstorms.

A NWS Birmingham survey team was able to find very minor and spatially isolated timber damage along Tutwiler Road. This was the only damage observed on the survey. Radar data indicated a weak TVS northwest of Highway 69 in an inaccessible area.

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

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 04:54 UTC and running to 07:24 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.
