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 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 mphthis tornado

    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

49 damage points were recorded along this path by NWS BMX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 125 mph.

  • Road blocked by downed trees
  • Carport uplifted and destroyed. Small trees down in area.

What the Weather Service recorded

A multi-day severe weather event produced all modes of severe weather across Central Alabama. An upper low parked over the Midwest States and an upper ridge over the Florida Peninsula produced a deep layer of moisture and shear over Alabama. A slow moving surface cold front provided the focus for severe storms late Saturday night and continuing through Monday morning.

National Weather Service meteorologists surveyed damage in northwest Macon County and determined that it was consistent with an EF2 tornado, with maximum winds near 125 mph. The tornado touched down in the area of Tysonville Road, with only sporadic tree limbs and small trees uprooted. Damage became more concentrated along County Road 138, where the attached carport of a house was ripped away and destroyed. Numerous trees, mostly pine, were uprooted along a path of several hundred yards. On County Road 40, the damage became more intense, with dozens of trees uprooted.|The top of a grain silo was blown off, with roofing material scattered southward, before the tornado reached the cotton gin in Milstead. Here, the main structure sustained significant damage, with failure of the roofing system and outer walls of the structure, earning the EF2 rating. Most of the inner walls remained standing, and two large buildings adjacent to the main structure only sustained comparatively minor roof and siding damage. Just east of the structures, significant tree damage was observed around a small lake. Along the road and railroad immediately south of the cotton gin, numerous concrete power poles were pulled down in a northward direction across the railroad tracks, and a pivot irrigation system was flipped in a large field. The tornado continued eastward, where the Auburn University E.V. Smith Research Center sustained damage to several buildings on the property, with one farm shed partially collapsing and roofing material blown northward across the road. Widespread tree damage continued along County Road 9 for around three miles, although most of the trees that were uprooted were pine trees. There was also occasional minor damage to roofing on homes, mostly caused by trees. Damage became much more sporadic as the tornado passed through the Franklin community, with only a few trees uprooted. There was a slight uptick of more concentrated tree damage on the east side of County Road 27 before the tornado dissipated.

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.
