EF0 tornado, Milton, Tennessee, February 6, 2019

This EF0 tornado ran 1.2 miles across Rutherford County on February 6, 2019, touching down at 2:35 PM CST and reaching 75 yards wide. It killed nobody, and did $25,000 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 mphthis tornado

    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 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. 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

14 damage points were recorded along this path by NWS OHX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 80 mph.

  • trees snapped along treeline and tree limbs blown down across fields
  • debris from carport in fields
  • minor roof damage to mobile home

What the Weather Service recorded

Heavy rain and thunderstorms produced 2 tornadoes and widespread flash flooding across Middle Tennessee from the afternoon of February 6 through the early morning hours on February 7. A warm front that had moved northward into Kentucky early in the day on February 6 sank back southward to near the Interstate 40 corridor by the afternoon, sparking numerous showers and thunderstorms along and just north of the front. As the front effectively stalled in a west-to-east line along the Interstate 40 corridor, showers and storms continued to redevelop and move across the same areas. With rainfall rates approaching 1-2 per hour at times, this led to widespread flash flooding across Humphreys, Dickson, Cheatham, Davidson, Wilson, Smith, Jackson, Putnam, and Overton Counties. This flooding resulted in numerous closed roadways, dozens of water rescues, flooded homes and businesses, significant rises on area creeks and rivers, and unfortunately one fatality in Cheatham County. Total rainfall amounts ranged from 3 inches to nearly 7 inches across these counties. In addition to the flooding, thunderstorms produced two EF-0 tornadoes in Rutherford and Wilson Counties. Lightning also struck homes in Overton and Jackson counties, causing significant fire damage.

An EF-0 tornado touched down along West Trimble Road just south of Milton and moved northeast across Halls Hill Pike before lifting south of Highway 96. One large barn west of Halls Hill Pike was destroyed, with debris from the barn blown up to 500 yards away. Two homes along Halls Hill Pike received minor roof damage, an outbuilding lost part of its roof, and a carport was destroyed. Dozens of trees were snapped and uprooted along the narrow path.

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 Marginal Risk. The outlook in force was issued at 19:40 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.
