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.

  1. F040 to 72 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. F173 to 112 mph

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

  3. F2113 to 157 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. 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.

  5. F4207 to 260 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. 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.

  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.

What the Weather Service recorded

A tornado touched down on the on the East side of interstate 75 at the Ky 21 exit at 445 am est. There the tornado destroyed a Sunoco gasoline station and ripped the roof of a Howard Johnson's motel. The tornado moved East-Northeast across the South side of Berea to just East of Ky 25 before dissapating around 450 am est. The tornado damaged around 800 homes and 40 businesses. 35 houses were destroyed or eceived major damage, while 26 business were destroyed or received major damage. Home damage was estimated at 6.7 million dollars...while damage to businesses was estimated at 6.1 million dollars. There were only minor injuries reported with the most serious being a broken collar bone. The tornado caused a storage tank to topple on the Parker Seal plant which produces O-rings for the space shuttle mission. Also damaged were parts of Berea College. Most of the damage there was due to fallen and uprooted trees. The "Old Town" section of Berea, where craftspeople make and sell high quality furiniture and other goods saw several businesses badly damaged. The roof of the town's old train depot, now a tourist center, caved in. Many homes were reported as flattened. The Red Cross, Salvation Army and 130 members of the National Guard were sent to aid the cleanup effort. The National Weather Service storm survey the damage path revealed an F2 tornado embedded in straight-line winds.

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

The warnings

9 minutes of warning. NWS LMK issued a tornado warning for this county at 09:36 UTC, 9 minutes before the tornado touched down, in force until 10:00 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 forecast that day

The Storm Prediction Center had this point in a Slight Risk. The outlook in force was issued at 05:43 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.
