F2 tornado, Magnolia to Attilla, Kentucky, March 28, 1997

From Magnolia to Attilla, this F2 tornado ran 5.0 miles across Larue County on March 28, 1997, touching down at 7:31 PM EST and reaching 300 yards wide. It killed nobody, and did $100,000 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 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 40 year old man was killed as an F3 tornado with winds estimated at 175 mph touched down near Bonnieville in Hart county and moved northeast 9 miles to the town of Magnolia in Larue county before lifting. The deceased man was killed in his house in Hammonville as the house was blown 50 yards away from its foundation. A few other poorly secured homes were lifted clean off their foundations as well. Most of the injured were hurt when the tornado crossed I-65 at exit 71 causing several accidents. In Hart county, 14 people were injured in addition to the 1 death. 32 houses and 8 mobile homes were heavily damaged or destroyed most in Bonnieville. DES officials estimate total damage at 1.4 million dollars. In Larue county, 22 houses and 20 barns were heavily damaged or destroyed with most of the damage in Magnolia. DES officials estimated total damage around 3 million dollars half of which was damage to a dairy farm. The farmer lost 80 cattle as as the barn collapsed on them. One man lost a restored model-T that he was used in car shows and exhibits. The only injury was to a Deputy Sheriff who rode out the storm in his cruiser. He badly bruised his hand and said he witnessed a near-by uninhabited car thrown more than 20 feet overtop of his cruiser.

A second tornado formed on the southern flank of the supercell that produced the tornado from Bonnieville to Magnolia. This second tornado formed as the first one dissipated. This second tornado touched down in Creal and did some damage there including a barn that was thrown across Highway 61. County road 2762 was also blocked by downed trees. Then the tornado proceeded northeastward and crossed Highway 210 into southern Larue county where again several trees and some power lines blocked the road there. There were 5 mobile homes and 4 barns destroyed and a church damaged in Pleasant Ridge. From there, the tornado moved northeastward into Marion county and dissipated 3 miles west of St. Joseph. Numerous trees and power lines were down across western Marion 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.
