F3 tornado, Melbourne to Calamine, Arkansas, March 5, 1996

From Melbourne to Calamine, this F3 tornado ran 46.5 miles across Izard, Sharp and Lawrence counties on March 5, 1996, touching down at 7:45 PM CST and reaching 150 yards wide. It killed nobody and injured 2, and did $2.6 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 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

The tornado first touched down 7 miles southwest of Melbourne. It moved east-northeastward, passing near the small community of Lunerburg, where it damaged and destroyed some homes and other structures. The tornado continued moving east-northeastward and hit the town of Mount Pleasant. A number of homes, mobile homes and other buildings were either damaged or destroyed. 2 people in Mount Pleasant sustained minor injuries. Numerous trees and power lines were also blown down along the tornado's path. The tornado exited Izard County about 3 1/2 miles northeast of Mount Pleasant at 815 pm.Damage along the track of the tornado was mostly F2. However, some structural damage was consistent with an F3 rating. Initial estimates place the amount of damage at around $1,000,000.An assessment of structural and other damage in Izard County revealed:17 homes damaged; 5 completely destroyed13 mobile homes damaged; 6 completely destroyed24 outbuildings damaged; 10 completely destroyed10 barns damaged; 6 completely destroyed3 chicken houses destroyed2 to 3 head of cattle killed

The Izard County tornado moved into Sharp County 2 3/4 miles west-southwest of Sidney at 815 pm. The tornado moved eastward and a few minutes later it struck the town of Sidney. 20 homes in Sidney were either damaged or destroyed. The tornado traveled along Highway 58, damaging more homes, barns, and other outbuildings. The tornado then began moving more in a northeasterly direction toward the Calamine community. Several more homes and other buildings were damaged. The tornado exited Sharp County about 2 3/4 miles east-northeast of Calamine around 845 pm. Numerous trees and power lines were also blown down along the tornado's path.Much of the damage was consistent with an F2 rating, with some damage noted as F3 in intensity. Preliminary estimates place the amount of damage at around $1,500,000.

The warnings

3 minutes of warning. NWS LZK issued a tornado warning for this county at 01:42 UTC, 3 minutes before the tornado touched down, in force until 02:30 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 05:38 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.
