EF2 tornado, Dotsonville to Beldon, Tennessee, February 24, 2018

From Dotsonville to Beldon, this EF2 tornado ran 4.1 miles across Montgomery County on February 24, 2018, touching down at 9:03 PM CST and reaching 200 yards wide. It killed nobody and injured 2, and did $7.0 million 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

98 damage points were recorded along this path by NWS LMK and NWS OHX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 135 mph.

  • Roof intact but completely ripped off. Thrown NE of house. Roof nailed.
  • . windows out on vehicles. roofs missing on 4 duplexes
  • Door lock in duplex blown open
  • One side of wall collapsed. not because of debis. NE side

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

An intense storm system brought severe thunderstorms to northwest Middle Tennessee during the late afternoon and evening hours on February 24. One supercell thunderstorm developed along a warm front that moved northward across the area during the afternoon, spawning one tornado along the Kentucky/Tennessee border in Robertson County that then moved northeast into Kentucky. Later in the evening, a Quasi-Linear Convective System (QLCS) moved into the area from the west, spawning three more tornadoes across Montgomery and Robertson Counties which damaged dozens of homes and businesses and caused millions of dollars in damage. The QLCS also caused wind damage in several other counties.

An EF-1 tornado touched down near the Dotsonville community just east of Dotsonville Road and south of Bradley A. Martin Road then moved northeast. Trees were blown down and a few homes suffered minor roof damage on Gip Manning Road and Hunting Creek Road. Hundreds of trees were snapped or uprooted and 12 to 15 homes were damaged on Martin Road, Deepwood Drive, and Deepwood Trail with two homes severely damaged. Dozens of more trees were blown down east of Rustys Lane and on High Point Road. The tornado then crossed the Cumberland River, continuing to blow down trees before lifting north of Hilltop Road. Montgomery County Emergency Management estimated damage at 1 million dollars. The beginning point, ending point, and path of this tornado were adjusted slightly in May 2019 based on new high resolution satellite data available in Google Earth.

An EF-2 tornado touched down in eastern Clarksville on Dunbar Cave Road and moved east-northeast across Interstate 24 north of Rossview Road before ending on Kirkwood Road. Several trees were blown down at the beginning of the path north of Dunbar Cave Road. Continuing northeast, several outbuildings were damaged at the Rossview High School football stadium. The tornado crossed I-24 and struck an industrial complex where three buildings were damaged and 75 cars in a parking lot sustained minor damage. The tornado intensified as it crossed Rollow Lane, blowing the roof off one home and downing numerous trees. Four duplexes lost their roofs on Holland Drive and many others were severely damaged. Dozens of homes sustained roof and exterior damage in the Farmington subdivision along Covey Rise Circle, Bainbridge Drive, Green Grove Way, and Edgewater Lane, and one home on Green Grove Way at Covey Rise Circle was shifted off its foundation and completely destroyed, causing two injuries. Another home was heavily damaged west of Gardenia Lane in an area of new homes before the tornado moved across open fields. The last damage was some uprooted trees on Kirkwood Road. Maximum winds were estimated to be 125 mph. Montgomery County Emergency Management estimated the damage from this tornado at 7 million dollars.

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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 00:42 UTC.

SPC's Day 1 convective outlook as it stood when the tornado began, read at the touchdown point. The same archive is on the radar archive.

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.
