EF0 tornado, Cooper to Enloe, Texas, January 10, 2020

From Cooper to Enloe, this EF0 tornado ran 0.1 miles across Delta County on January 10, 2020, touching down at 6:22 PM CST and reaching 100 yards wide. It killed nobody, and did $5,000 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

8 damage points were recorded along this path by NWS FWD, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 85 mph.

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 deep upper level trough and a humid and unstable environment resulted in an early severe weather event across North and Central Texas. Severe storms developed in the afternoon hours to the northwest and north of the DFW Metroplex. These storms eventually developed into an expanding squall line. A total of 5 tornadoes occurred with this event along with some damaging wind and smaller-sized hail.

A small supercell thunderstorm moved northeast into Delta County, Texas, spawning a brief tornado on the west side of the City of Cooper. The tornado formed about two blocks south of West Dallas Avenue in west Cooper, destroying a small outbuilding and causing minor roof and tree damage. The tornado moved northeast, crossing Dallas Avenue and pulling the roof and an exterior cinder block wall off of a small commercial building. Exterior siding damage also occurred to a two-story apartment complex nearby. The tornado continued toward the northeast, seriously damaging a large sheet metal cotton gin building. Minor tree and structural damage continued for approximately another 200 yards before the tornado dissipated south of State Highway 24. This tornado was rated an EF-0 with maximum winds of 85 mph.

The same supercell that produced the earlier Cooper tornado moved northeast about 4 miles and spawned a second very brief tornado near Enloe, in northern Delta County. The tornado touched down in an open field just southeast of Enloe, destroying a couple of small outbuildings and scattering the debris downwind a few hundred yards. The debris pattern exhibited a subtle cyclonic orientation, implying a brief, weak tornado. The tornado was rated an EF-0 with maximum winds of 75 mph.

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 0.10 chance of a tornado within 25 miles, in the hatched area where significant tornadoes were expected. The outlook in force was issued at 20:02 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.
