F1 tornado, Courtland to Athens, Alabama, December 16, 2000

From Courtland to Athens, this F1 tornado ran 5.1 miles across Lawrence and Limestone counties on December 16, 2000, touching down at 12:25 PM CST and reaching 30 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 mphthis tornado

    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 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

The tornado first touched down in Lawrence County northeast of Courtland in open farm land. It traveled northeast into Limestone County crossing the Tennessee river and causing damage about 2.9 miles south of Coxey in southwest Limestone County. The tornado travelled approximately a half mile on land in Limestone County before dissipating rapidly. One house lost a portion of a roof, two other homes sustained damage from falling trees, several boat houses and out-buildings were destroyed, and numerous large trees were downed. The survey team could find no damage in Lawrence County, however, two people photographed the tornado, one on the east side of Courtland looking northeast and one at Poplar Point in Limestone County looking northwest as it came ashore on the Limestone County side of the river.Beginning: 34 42.569/87 13.850 Ending: 34 45.874/87 10.228

A second tornado began 5.1 miles west-northwest of Athens just south of O'Neal. The tornado travelled in a northeasterly direction crossing SR 99 where several houses were damaged heavily. Continuing northeast the tornado crossed CR 63 and damaged several houses and destroyed three mobile homes just south of Cross Key. The tornado then crossed CR 26 and SR 127 before dissipating about 5.0 miles north of Athens. The tornado was rated an F2 with no known injuries reported. The total tornado path was 4.8 miles long and about 60 yards wide. The tornado began at 12:38 PM and dissipated at 12:44 PM. Beginning: 34 50.326/87 03.032 Ending: 34 52.552/86 58.748

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 Moderate Risk. The outlook in force was issued at 17:53 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.
