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 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.

29 damage points were recorded along this path by NWS BMX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

• larger tree down across field.
• tree along S roadbank appeared to have been partially uprooted and was cut to clear road. treetop snapped out to the right
• a few large limbs gnarled or snapped

A strong upper level disturbance caused a wave of low pressure to form along a quasi-stationary front and move eastward along the Highway 80 and Interstate 85 corridors. This allowed a warm front to lift northward across the southeast portions of Central Alabama. North of the warm front, a line of showers with sporadic lightning strikes along an inverted trough was able to produce damaging winds despite a cool and stable air mass at the surface, knocking down numerous trees from Tuscaloosa County to Randolph County during the first part of the morning. A QLCS ahead of the cold front moved eastward later in the morning from Lowndes County to Barbour County, producing sporadic damaging winds. Additionally, bookend vortices and embedded supercell structures several weak tornadoes and one strong tornado.

National Weather Service meteorologists surveyed damage in northwest Pike County and determined that it was consistent with an EF0 tornado, with maximum winds near 70 mph. Damage was limited to a few snapped and uprooted pine trees along its path. A tornado debris signature was noted with this storm.

National Weather Service meteorologists surveyed damage near the Troy Municipal Airport in northern Pike County and determined that it was consistent with an EF0 tornado, with maximum winds near 80 mph.||The tornado formed near the intersection of Lake Road and Oak Grove Road just southwest of Troy Municipal Airport. Branches and a couple of trees were uprooted along Oak Grove Road. The tornado continued east-northeastward, removing the roof from a barn and uprooting a few more trees, before crossing the north-south runways at the airport. The tornado passed south of the terminal and very near the KTOI ASOS. Winds backed from 200 degrees to 170 degrees and then veered to 260 degrees while gusting to 47 mph. The tornado uprooted a few trees before dissipating west of Highway 231.

National Weather Service meteorologists surveyed damage in northeast Pike County and determined that it was consistent with an EF0 tornado, with maximum winds near 75 mph. The tornado formed in a wooded rural area south of Highway 223 and the Sandfield community. Several trees were uprooted as it crossed a dirt road and County Road 6615. The tornado appeared to dissipate prior to reaching the Bullock County line. A brief tornado debris signature was also observed on the KMXX radar.

1 minute of warning. NWS BMX issued a tornado warning for this county at 15:32 UTC, 1 minute before the tornado touched down, in force until 15:55 UTC.

The county was under a tornado watch, issued at 13:51 UTC and running to 16:37 UTC.

Lead time is measured from the issue of the warning in force to the touchdown time in the database, both of which were recorded to the minute by different people.

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 12:57 UTC.

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.
