F3 tornado, Clarendon to Hawkins, Arkansas, January 21, 1999

From Clarendon to Hawkins, this F3 tornado ran 16.0 miles across Monroe and St. Francis counties on January 21, 1999, touching down at 5:02 PM CST and reaching 200 yards wide. It killed nobody and injured 9, and did $500,000 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 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 mphthis tornado

    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 strong tornado was spawned in southern Monroe County. The tornado flipped over a tractor 8 miles south of Brinkley. About 3 miles southeast of Brinkley, the tornado destroyed a home with nothing left but the foundation. As the tornado moved northeast, the tornado damaged some transmission towers. The tornado tracked through much of eastern Monroe County and weakened some before moving into St. Francis County (Memphis County Warning Area) and the Wheatley area.

The tornado moved into the extreme southwest corner of St. Francis county from Monroe county. It touched down several times and then lifted back into the air. The most severe damage occurred in and near Wheatley. Thirteen homes were completely demolished and six other homes sustained structural damage. Further along its path, the tornado hit a farm about 4.5 miles northeast of Wheatley. The farmhouse lost part of its roof. Two or three machine sheds were demolished, several other outbuildings were damaged, grain storage bins were flatted and blown several hundreds of feet away and irrigation equipment suffered extensive damage.

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

The warnings

15 minutes of warning. NWS LZK issued a tornado warning for this county at 22:47 UTC, 15 minutes before the tornado touched down, in force until 23:35 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 High Risk. The outlook in force was issued at 10:55 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.
