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.
EF065 to 85 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
EF186 to 110 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
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.
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.
EF4166 to 200 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
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.
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
33 damage points were recorded along this path by NWS BMX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 100 mph.
- Tornado likely continued eastward and then dissipated in a relatively inaccessible wooded area west of Collier Creek.
- End Point. Tornado dissipated near a wooded area before crossing Cty Rd 2.
- three sided lumber shed destroyed. pole barn structure.

What the Weather Service recorded
Tropical Cyclone Laura moved inland over southwest Louisiana and tracked northeast along the Mississippi River. Several convective outer bands on the east side of Laura produced severe storms over Central Alabama. An abundance of tropical moisture coincided with areas of diurnal heating to promote an unstable atmosphere which also interacted with areas of favorable low-level wind shear. Straight-line winds caused the majority of the damage both days, but a few tornadoes also developed during the afternoon of August 28th.
National Weather Service meteorologists surveyed damage in northeastern Winston County and determined that it was consistent with an EF1 tornado, with maximum winds near 105 mph.||The tornado developed in a wooded area east of County Road 195. The tornado tracked northeast, crossing County Road 6 near Sandy Creek, where it caused minor timber damage. The tornado caused minor damage to the roof of a chicken house just off of County Road 415. The tornado continued northeast where it approached Highway 33 west of Moreland. The tornado caused notable timber damage as it crossed Highway 33, then it continued northeast across County Road 3163 where it removed sheathing from under a manufactured home, destroyed a small outbuilding, and removed portions of siding and sheathing from a manufactured home. The tornado then crossed County Road 63, or Cheatam Road, where it removed a portion of the roof from a manufactured home, damaged two garage doors, and blew out a window of an outdoor storage building. The tornado continued northeast before dissipating near Collier Creek.
NWS Meteorologists surveyed damage in northeastern Winston County and determined it was consistent with an EF1 tornado, with maximum winds near 95 mph.||The tornado developed near a mobile home manufacturing facility where it peeled portions of sheet metal from the roof of the building, removed some skirting from a modular building and blew out two windows from a vehicle. The tornado then crossed Highway 33 where it remained just north of County Road 24. The tornado continued east through wooded, uninhabited and inaccessible area. The tornado dissipated before reaching County Road 2, where there was no observable damage.

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 20:00 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.
