A National Weather Service damage survey team has determined that tornado damage occurred over portions of Tippah and Alcorn counties in north Mississippi and in McNairy County in west Tennessee. The tornado was not continuously on the ground making short touchdowns and retreating back into the air.

In Tippah County…the first tornado touchdown occurred just south of Chalybeate near the intersection of County Road 225 and County Road 222. Many trees were knocked down in the area. One tree knocked down half of a brick chimney on a house located on County Road 222-a. A couple of Mobile homes in the area were also damaged. The tornado was rated an EF-0 in this area with winds speeds estimated to be around 60 mph. The width of the tornado was estimated to be around 50 yards.

At least one Mobile home was destroyed and several other nearby Mobile homes were also damaged. Numerous trees were knocked down in the vicinity. The tornado was rated an EF-1 in the this area with wind speeds estimated to be around 90 mph. The width of the tornado was estimated to be around 100 yards.

One business was destroyed and a second business was damaged along U.S. Highway 45. The tornado continued northeast and traveled through a forested area where numerous trees were blown down. The tornado continued across Highway 142. Two homes received roof damaged and one Mobile home was destroyed in the area. The tornado was rated an EF-1 with winds speeds estimated to be around 105 mph. The width of the tornado was estimated to be around 150 yards.

Results of tornado surveys.

Here are the results of surveys by the National Weather Service of tornadoes spawned by the supercell storm that moved across Tennessee the evening of Feb 5th.

After surveying damage from Tuesday night’s tornadoes that struck middle Tennessee, it has been determined that four individual tornadoes occurred along a path extending from Clifton to northeast of Lafayette.

The first tornado touched down over northeast Hardin County, moved near Clifton, and lifted near Flatwoods in northern Wayne County.

A second tornado touched down in extreme southeast Perry County, a few miles northeast of the end of the previous tornado track. This tornado remained on the ground as the storm moved across northwest Lewis County, and into Hickman County. The tornado struck the brushy community, then turned toward the left just east of Centerville before dissipating.

The first two tornadoes have been rated as either EF-0 or EF-1.

A third tornado touched down near the end of the previous tornado track east of Centerville, and passed through Fairview, in northwest Williamson County, before lifting near the Davidson County line. This tornado has been rated as either EF-1 or EF-2.

The supercell thunderstorm continued to move northeastward, across Nashville, before spawning a fourth tornado, which dropped down on the south side of Gallatin, near the Cumberland River. This tornado moved through Castalian Springs, extreme northern Trousdale County, across Macon County, striking the northwest side of Lafayette, before moving into Kentucky, where it finally lifted northeast of Tompkinsville. The path length of this tornado was approximately 51 miles.

A total of 24 fatalities have so far been attributed to this tornado: 7 in Sumner County, 3 in Trousdale County, and 14 in Macon County.
