EF0 tornado, Refugio Rooke Arpt to Greta, Texas, April 16, 2015

From Refugio Rooke Arpt to Greta, this EF0 tornado ran 0.1 miles across Refugio County on April 16, 2015, touching down at 2:51 PM CDT and reaching 50 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

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

  • 6 broken power poles and several large tree branches snapped.

What the Weather Service recorded

A deep upper low was located over the Four Corners region on April 16th while a strong jet streak in the subtropical jet stream across northern Mexico moved into South Texas. Scattered thunderstorms formed near a weak boundary moving north through the Coastal Bend. A storm that formed over Bee County intensified into a heavy precipitation supercell. This storm produced three weak tornadoes as it moved across Refugio County.

A brief rope tornado lasted around 30 seconds.

A weak tornado briefly caused damage near Quintana. The tornado damaged six utility poles and broke several large tree limbs. NWS survey team estimated wind speeds were near 80 mph.

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

The warnings

8 minutes of warning. NWS CRP issued a tornado warning for this county at 19:43 UTC, 8 minutes before the tornado touched down, in force until 20:15 UTC.

The county was under a severe thunderstorm watch, issued at 19:28 UTC and running to 01:35 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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 16:30 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.
