EF0 tornado, New Haven to Deerfield, Tennessee, December 16, 2019

From New Haven to Deerfield, this EF0 tornado ran 3.8 miles across Lawrence County on December 16, 2019, touching down at 4:55 PM CST and reaching 25 yards wide. It killed nobody, and did $15,000 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

23 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 85 mph.

  • Front porch removed from house and blown northward. About 25% roof loss.
  • House was lifted and sat back down pulling toilet upward by a foot.
  • Approximately one dozen pines uprooted
  • About one dozen uprooted pines

What the Weather Service recorded

A powerful late fall storm system moved across the eastern U.S. on December 16, 2019, bringing widespread severe thunderstorms and numerous tornadoes to the Gulf Coast states and Tennessee Valley. Across Middle Tennessee, a line of showers and thunderstorms moved across the area during the afternoon hours, bringing wind damage and two EF-0 tornadoes to counties near the Alabama border. Widespread heavy rainfall also caused flash flooding in many areas.

This EF-0 tornado touched down near the intersection of Buck Branch Rd and Piney Road where the front porch and part of the roof was ripped off one house. The toilet in the house was uplifted approximately one foot above the flooring with the plumbing still attached. No evidence of the house shifting on the foundation was found. As the tornado traveled northeastward, the tornado caused sporadic tree damage along Hood Road and collapsed a large farm outbuilding on Granddaddy Road. One house on Grandaddy Road also had a large number of shingles removed along with approximately ten pines uprooted. The tornado continued to damage and blow down trees until it crossed Kelso Road where an outbuilding sustained roof damage. The tornado dissipated before it reached Shotwell Road.

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

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 Slight Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 19:25 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.
