EF2 tornado, Tampico, Indiana, March 1, 2017

This EF2 tornado ran 0.3 miles across Jackson County on March 1, 2017, touching down at 5:45 AM EST and reaching 50 yards wide. It killed nobody, and did $45,000 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 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

25 damage points were recorded along this path by NWS IND and NWS LMK, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF2. The highest wind the damage implies is 116 mph.

  • metal outbuilding heavily damaged with debris fanned out from ESE to NE
  • Metal roof blown off ranch home
  • over 100 hardwood and softwood trees snapped and uprooted. Convergence noted.
  • 50 or more softwood trees snapped and uprooted

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 low pressure system brought very warm and unstable air for late February and early March to central Indiana. The result was severe thunderstorms and 7 tornadoes from the 28th of February to March 1st. A surface frontal system interacted with an unstable and high shear environment to produce the severe weather.

A brief EF-2 tornado, with winds up to 115 mph, touched down with the tornado lifting a garage up and partially off its foundation, turning the garage about 30 degrees, and resting it on top of a pickup truck which was in the garage. A frame ranch house next to the garage lost a substantial portion of its roof which was deposited to the northeast behind the house. Insulation from the house was splattered against the entire east wall of the house and the entire remaining roof of the east side of the home. A 25 foot trailer in the driveway was lifted, turned 180 degrees, and flipped onto its side, resting against the home.||This brief EF-2 tornado was embedded within a 12 mile long downburst path, which extended from just east of Medora to just west of Crothersville. Within this downburst path, straight line winds to at least 115 mph collapsed 3 metal transmission towers, all laying to the east. These transmission towers were about 7 miles east of the tornado 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 Enhanced Risk, with a 0.05 chance of a tornado within 25 miles. The outlook in force was issued at 05:42 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.
