EF0 tornado, Villa Nova to Uniopolis, Ohio, March 31, 2023

From Villa Nova to Uniopolis, this EF0 tornado ran 8.4 miles across Mercer and Auglaize counties on March 31, 2023, touching down at 12:45 AM EDT and reaching 200 yards wide. It killed nobody, and did $100,000 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

27 damage points were recorded along this path by NWS ILN, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF1. The highest wind the damage implies is 105 mph.

  • Minor roof damage to two houses. A outbuilding blown over.
  • Grain bin gone. Barn building collapse.
  • Tree across field, swirling dirt. Start of tor.

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

Showers and thunderstorms overspread the area during the late evening hours ahead of a strong low pressure system and an associated cold front moving through the Ohio Valley.

Aerial pictures provided by the Auglaize County Emergency Management Agency indicated that the tornado likely began near Koenig and Noble Roads, where barn and tree damage was first noted. Shingles were also lifted off the roof of a home on Koenig Road and roof debris was blown behind the home. Aerial footage indicated the tornado moved to the northeast with debris noted in multiple fields. An outbuilding was destroyed near the Easterly Road and State Route 116 intersection. Multiple hog barns and a farmstead were destroyed along the path, with winds estimated to be 85 mph at peak intensity. The tornado likely lifted or dissipated around or north of Barber Werner Road and no additional tornado damage was evident to the northeast of here.

The tornado first touched down near Indian Trail Road and State Route 716. The tornado tracked east-northeast and crossed into Auglaize County near the intersection of State Route 364 and Minster Egypt Pike at 2348EST. The tornado continued northeast into Auglaize County before lifting near Bensman Road at 2353EST. Occasional tree and minor structural damage was noted along its path.

The tornado initially touched down at 2345EST in Mercer County near the intersection of Indian Trail Road and State Route 716 and crossed into Auglaize County near the intersection of State Route 364 and Minster Egypt Pike at 2348EST. The tornado continued northeast and crossed through the north end of Minster before lifting near Bensman Road. Tree and structural damage was noted with some of the most significant structural damage done to barns near Egypt.

The first sign of visible damage associated with this tornado occurred on Owl Creek Road. At one residence, two large trees were knocked down while a barn was destroyed at another residence. The tornado strengthened as it moved to the northeast, removing a significant portion of a warehouse building roof and snapping several power poles. Just northeast of here, a large commercial greenhouse was completely leveled. The tornado then crossed the intersection of U.S. 33 and Interstate 75, causing significant roof damage and partial exterior wall collapse to an industrial building. At this point, the tornado was at its strongest with estimated winds of up to 110 mph.||On the east side of Interstate 75 and just north of U.S. 33, a truck stop experienced significant damage and a few semi-trailers were blown over. Just northeast of here, a private campground suffered significant damage. At the campsite, numerous trailers were flipped over and a large meeting hall had its roof removed. Several trees were also knocked down. Seven people were injured when the trailers were flipped at the campground.||As the tornado continued northeast, several farmhouses were damaged and outbuildings were damaged or destroyed between Wapakoneta and Uniopolis, particularly along Middle Pike. Considerable debris was noted in nearby fields. A historic brick school building was also destroyed on Brown Road. Numerous trees were also snapped and uprooted along the path. Sporadic damage to trees and outbuildings continued to the northeast before the tornado apparently lifted near the Auglaize/Allen County line.||This tornado started at 2354 EST, March 31st, 2023 and ended at 0007 EST, April 1st, 2023. The injuries occurred just before midnight EST so were included in the March 2023 Storm Data for Ohio, Southwest.

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 01:04 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.
