EF1 tornado, Vienna, Indiana, March 1, 2017

This EF1 tornado ran 2.1 miles across Scott County on March 1, 2017, touching down at 6:05 AM EST and reaching 125 yards wide. It killed nobody and injured 10, and did $250,000 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 mphthis tornado

    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

37 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 EF1. The highest wind the damage implies is 116 mph.

  • large detached garage destroyed
  • metal outbuilding heavily damaged with debris fanned out from ESE to NE
  • Metal roof blown off ranch home
  • cinder block out building 300 yards W of this location - wall partially collapsed

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

The combination of a moist and unseasonably warm air mass and an approaching low pressure system and cold front brought multiple rounds of severe weather to southern Indiana during the early morning hours on March 1. In the end, there were 5 tornadoes across southern Indiana, the strongest being an EF-2 that tracked through portions of Dubois County. In addition to the tornadoes, there were several areas of intense straight-line winds estimated up to 100 mph in places. The impacts included numerous areas of structural damage and downed trees. The widespread heavy rain brought the Muscatatuck River at Deputy into minor flood.

The National Weather Service in conjunction with Scott County Emergency Management, determined an EF-1 Tornado touched down 4 miles south of Scottsburg, on Interstate 65 at approximately mile marker 25.5. After overturning a semi tractor-trailer on the Interstate, the tornado moved east-southeast, collapsed a wall on a large cinder block building, then destroyed two metal outbuildings and flipped an unanchored mobile home on a farmstead 1/4 mile east. It continued skipping east, uprooting and snapping trees and destroying an anchored mobile home on Underwood Road. Three residents were in the home at the time when it rolled over and disintegrated. They received minor injuries. The tornado then damaged an outbuilding and numerous more trees as it headed east toward Double or Nothing Road. Near the intersection of Double or Nothing Road and Radio Tower Road, it destroyed a large garage and pushed a double-wide manufactured home off its foundation. The tornado was embedded in a 1-2 mile wide area of 60 to 80 mph winds that extended further east for over 10 miles, and may have briefly touched down within this area as well.||Within the county, this tornado and two areas of straight-line wind resulted in approximately 23 minor injuries and the closure of seven roadways across the county.

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.
