The rating scale
Tracks are drawn in the color of the rating. The Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.
F040 to 72 mph
Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.
F173 to 112 mphthis tornado
Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.
F2113 to 157 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.
F3158 to 206 mph
Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.
F4207 to 260 mph
Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.
F5261 to 318 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.

What the Weather Service recorded
A tornado caused considerable damage 9 miles south of Birmingham, in the Vestavia Hills and Hoover communities. The tornado first touched down in the Tal-Heim subdivision near Interstate 65 and Rocky Ridge Road. A ham radio operator, equipped with an anemometer, recorded a 66 mile an hour wind as the tornado was initially reaching the ground. The tornado traveled northeast and ended just northwest of the intersection of Rocky Ridge Road and Old Rocky Ridge Road. The greatest damage occurred in a small area from Wisteria Road through the Buckhead subdivision. Eighty seven homes received varying degrees of damage due mainly to falling trees, and seven of those homes were totally destroyed. Many homes had sections of roof removed, shingles torn off, and broken windows. Numerous trees were uprooted or snapped off and power lines were blown down along the path. Several automobiles and outbuildings were also destroyed by falling trees. Beginning: 33 23.915/86 47.443 Ending: 33 24.883/86 46.460

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.
