From Clifton to Yokley, this F5 tornado ran 69.4 miles across Wayne, Lawrence, Giles and Maury counties on April 16, 1998, touching down at 4:50 PM CDT and reaching 1,760 yards wide. It killed 3 people and injured 36, and did $13 million of property damage.

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 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. 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 mphthis tornado

    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

The tornado killed 3 people in Wayne county. 2 females, their ages 75 and 57, were killed in a modular home on Lay Creek Rd. Another female, age 69, was killed on Chalk Creek Road in a wooden frame home. The tornado left nothing but the foundation. A lumber yard was destroyed. Many trees were down in the path of the tornado. Many houses and mobile homes were destroyed. 34 homes were completely destroyed, 14 homes had major damage and 22 had minor damage. .

Many fine homes, some even brick, were completely leveled. Trees were uprooted or blown down, power lines were down, 75 utility poles were blown down around the county. People who were at their homes went to the basement, or in a closet, or in a bathroom. The EMA report of a one ton Dodge flatbed truck, which weighs almost 5000 pounds, being hurled 20 miles, could not be confirmed. Therefore this account should be discounted. However, the EMA director verfied a sedan being carried 1/2 mile. A tree was debarked by the flying debris. A 200 yard wide path of pasture land had grass pulled out. Clumps of dirt was pulled up from the ground. Several livestock was killed.

The most extensive damage was north of Yokley. There were downed trees and power lines, a ruptured gas tank, cars overturned, and homes damaged. 5 homes and 8 mobile homes were destroyed in Giles county.

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.
