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.

  • porch and carport collapse on home.
  • .south edge. pine tree on awning
  • .also shingle removed from home and fascia damage. South edge.
  • .much of roof removed from a well built older home. Another tree fell on a hourse causing significant roof damage.

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 upper level trough and cold front moved through the area. There was sufficient instability and shear for a few strong to severe thunderstorms across the area, including a few tornadoes. However, all of the tornadoes were rated EF0, and the most severe weather remained just west of southeastern Alabama.

Late Christmas Eve, a well amplified upper level trough dug into the southern Plains. In response, a surface low developed Christmas morning over southern Texas. As the upper low deepened and tilted negatively, the surface low strengthened as it moved eastward. By Christmas afternoon, a swath of severe weather swept across the Deep South, with discrete supercells and a broken line of thunderstorms in trail. These thunderstorms moved across central Alabama during the evening hours, bringing with them strong straight line winds, numerous tornadoes, as well as flooding.

An EF0 tornado touched down in northwestern Dale county near the Highway 231 Pea River Bridge and traveled northeastward into Pike County. In Dale county, trees were twisted and partially snapped, but no structural damage occurred. In Pike county, the tornado strengthened to EF1, but the Dale county portion of this tornado was rated EF0.

The tornado touched down in far northern Dale County (See Storm Data Tallahassee) along Highway 231 near the Pea River. The tornado tracked northeastward and crossed County Road (CR) 200 before it entered Pike County. The tornado continued northeastward and produced damage along CR 4425 and CR 4438. The tornado lifted near the intersection of CR 4427 north of CR 4421. Numerous trees were either snapped off or were uprooted along the damage path. The most significant damage occurred along CR 4425 where 2 homes sustained roof damage and 2 chicken houses were damaged. Also along CR 4438, a barn lost its roof with the tin being thrown over one half mile and hardwood trees were snapped and uprooted. The total tornado path length was 5.36 miles and was 300 yards wide at its widest point. The tornado first touched down at 527 pm CST.

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

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.
