EF0 tornado, Ottawa Putnam Co Arp, Ohio, March 5, 2024

This EF0 tornado ran 0.2 miles across Putnam County on March 5, 2024, touching down at 2:34 PM EST and reaching 50 yards wide. It killed nobody, and did $75,000 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

2 damage points were recorded along this path by NWS IWX, in the Damage Assessment Toolkit the survey teams carry. The strongest indicator was rated EF0. The highest wind the damage implies is 70 mph.

  • Significant loss of roof, shingles, and some siding. Poorly built attached garage collapsed. Damage direction is northeast.
  • Tornado quickly dissipated in an open field just north of the intersection of Road H5 and Road 5H, just east of SR65.

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 brief EF-0 land spout tornado occurred south of Leipsic, Ohio on the afternoon of March 5th. Several photos and videos were taken of the tornado along SR65 near the intersection with Road H5. The tornado caused damage to one home on Road H5, with loss of the roof, shingles, and some siding. A poorly built attached garage collapsed, and debris could be seen scattered to the northeast of the home. The tornado quickly dissipated in an open field just north of the intersection of Road H5 and Road 5H, just east of SR65.

A brief EF-0 land spout with winds estimated at 70 mph was confirmed near Leipsic, OH. Emergency manager and trained spotters confirmed tornado. Several photos and videos of the land spout along SR65. One home near the intersection of Road H5 and SR65 sustained damage to the roof and siding. An attached garage collapsed and debris was scattered to the northeast of the property. Time was estimated from radar.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down.

Every warning and watch covering the touchdown point that day, from the Iowa Environmental Mesonet's archive of National Weather Service products. 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 General Thunderstorms Risk. The outlook in force was issued at 16:15 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.
