EF2 tornado, Forty Eight Creek Br to North Highland, Tennessee, March 25, 2021

From Forty Eight Creek Br to North Highland, this EF2 tornado ran 22.1 miles across Wayne, Lewis and Lawrence counties on March 25, 2021, touching down at 7:30 PM CDT and reaching 350 yards wide. It killed nobody and injured 1, and did $350,000 of property damage.

The rating scale

Tracks are drawn in the color of the rating. The Enhanced Fujita scale rates the damage rather than measuring the wind: the speeds are what that damage is taken to imply.

  1. EF065 to 85 mph

    Light damage. Surface peeled off some roofs, gutters and siding damaged, branches broken, shallow-rooted trees pushed over.

  2. EF186 to 110 mph

    Moderate damage. Roofs badly stripped, mobile homes overturned or badly damaged, exterior doors lost, windows broken.

  3. EF2111 to 135 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. EF3136 to 165 mph

    Severe damage. Whole stories of well-built houses destroyed, large buildings badly damaged, trains overturned, trees debarked, heavy cars lifted and thrown.

  5. EF4166 to 200 mph

    Devastating damage. Well-built houses leveled, structures with weak foundations moved some distance, cars thrown and large missiles generated.

  6. EF5over 200 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.

The damage survey

45 damage points were recorded along this path by NWS OHX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 130 mph.

  • Dozens of trees blown down
  • Uprooted softwoods. Some roof damage
  • 5 ETLines collapsed. Power is out in all of Wayne County.
  • Trees laying to N poll damage

Survey points are preliminary and are the raw material the published rating was built from. Source: NWS Damage Assessment Toolkit.

What the Weather Service recorded

A potent weather system on March 25, 2021 led to an outbreak of supercells and tornadoes across Mississippi, Alabama, Georgia, and Tennessee, some of which were strong to violent. Across Middle Tennessee, a left-moving or anticyclonic supercell caused dozens of reports of large hail and wind damage from the Nashville metro northward to the Kentucky border during the afternoon. Later in the evening, additional supercell thunderstorms developed and spawned three tornadoes in Wayne, Lewis, Lawrence, and Rutherford Counties, as well as more reports of hail and wind damage.

A strong EF-2 tornado touched down just northeast of the city of Waynesboro between Highway 64 and Highway 99. The tornado increased in intensity rapidly as it tracked through neighborhoods along Highway 99. A few trees and outbuildings were blown down and destroyed at the beginning of the track before the tornado moved across Steele Street, Hassell Drive, High Street, and Natural Bridge Road, taking the roofs off several homes and causing one minor injury. Five high power TVA electrical steel poles were bent to the ground in this area, knocking out power to all of Wayne County. Continuing northeastward, the tornado destroyed a barn on York Road and damaged several homes on Fortyeight Creek Road. The tornado then moved through rural, forested and hilly terrain with few roads for a total of 22.2 miles across northeast Wayne, extreme southern Lewis, and extreme northwestern Lawrence Counties, blowing down hundreds of trees before finally lifting around 4 miles northwest of Summertown.

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

The warnings

26 minutes of warning. NWS OHX issued a tornado warning for this county at 00:04 UTC, 26 minutes before the tornado touched down, in force until 00:45 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 Moderate Risk, with a 0.15 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 22:26 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.
