F2 tornado, Yokena to Edwards, Mississippi, December 7, 2004

From Yokena to Edwards, this F2 tornado ran 26.0 miles across Claiborne, Warren and Hinds counties on December 7, 2004, touching down at 1:20 AM CST and reaching 400 yards wide. It killed nobody, and did $550,000 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

This tornado touched down just east of US Highway 61, 3 miles north of the Claiborne county line. As the storm moved northeast, several hundred trees were blown down or uprooted, including many large 2-3 foot diameter trees. Some power lines were also blown down along the path including some minor roof damage to shingles and antennas. The tornado was on the ground for 9 miles in Warren county. The tornado continued northeast across a small portion of Claiborne county and then into Hinds county where it dissipated 5 miles southwest of Bolton. The total path length was 26 miles.

This tornado moved into Claiborne county from Warren county and tracked across the far northeast corner of the county for 4 miles. A few hundred trees were blown down along the southern bank of the Big Black River. The total path length of the tornado was 26 miles across Warren, Claiborne and Hinds county.

This tornado moved into Hinds county from Claiborne county and intensified as it tracked northeast across west-central Hinds county. A few thousand trees were uprooted and snapped along the 13 mile path. Just off State Highway 27, large barn was severely damaged and a home had its roof torn off along Newman Road. On Puckett Road, a home was damaged and the garage had its roof torn off. A few more homes sustained damage as the tornado moved northeast. The tornado dissipated 5 miles southwest of Bolton. The total path length across Warren, Claiborne and Hinds county was 26 miles.

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.
