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

9 damage points were recorded along this path by NWS HUN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 88 mph.

What the Weather Service recorded

A quasi-linear convective system progressed east through north Alabama and southern middle Tennessee from the late morning through the middle afternoon hours. A supercell within the line produced an EF-1 tornado in Franklin County northwest of Russellville. Damaging winds were reported at times along this line, knocking down trees, power lines, and producing damage to some homes. A second area of thunderstorms arrived during the mid to late evening hours in northwest Alabama, producing excessive rainfall and flooding in the Florence area.

A tornado touched down just west of Shady Grove Road. Damage to a small farm outbuilding and snapped cedar trees were observed. The tornado quickly moved through a residential farm and damaged the roof of a couple farm outbuildings, snapped more large branches, and downed more trees. The owner of the property managed to safely seek shelter in his tractor as the tornado quickly passed. More tree damage was noted to the northeast of the Shady Grove Road farm before it produced minor roof damage to chicken houses and a mobile home. The tornado appeared to have lifted near this location. Maximum winds were estimated at 88 mph, using snapped cedar trees as a damage indicator.

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

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. The outlook in force was issued at 16:20 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.
