EF1 tornado, Troy, Ohio, July 23, 2022

This EF1 tornado ran 1.8 miles across Miami County on July 23, 2022, touching down at 10:45 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 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

32 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 90 mph.

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

Thunderstorms associated with an upper level disturbance moved east across the region during the late morning hours.

The initial damage occurred near the intersection of Cheshire Road and Dorset Road, where several large tree limbs were downed. Damage became a little more concentrated near the intersection of Armand Drive and McKaig Avenue, where several large tree limbs and a few trees were downed. Tree damage also occurred at an apartment complex along Red Cedar Drive.||The most heavily concentrated area of damage occurred near Drury Lane and Ridge Avenue. Numerous very large, healthy trees were downed, with one trunk snapped at its base, and several other very large branches snapped not far off the ground. A couple of homes also had some minor roof damage. On West Simpson Street, just to|the east, a car was heavily damaged by a falling tree limb.||The damage path became narrower near Terrace Place, Market Street, and West Street. A bank sign was damaged and several more large trees and tree limbs were downed. In the neighborhood south of West Street, a few more homes had minor roof damage, with a fairly consistent area of tree damage observed as far southeast as Walker Street and Dakota Street.||Tree damage was also reported in other locations in Troy, such as Stanfield Road, West Ross Street, and Dakota Street. The rest of this damage is believed to have been caused by straight-line winds with speeds of 60 to 70 MPH.

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 Slight Risk, with a 0.02 chance of a tornado within 25 miles. The outlook in force was issued at 12:54 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.
