EF0 tornado, Kansas, Ohio, July 8, 2013

This EF0 tornado ran 0.1 miles across Seneca County on July 8, 2013, touching down at 9:02 PM EDT and reaching 15 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.

What the Weather Service recorded

Another day of heavy rain moved into Ohio bringing localized areas of 2 to 3 inches of rain. Runoff from these mainly afternoon and evening storms fell on saturated soils and caused the rivers and streams and streams to rise. Though the flooding was fairly widespread, most of the flooding was on roadways where it quickly receded. No homes were inundated and property damage was minimal.||A weak tornado touched down in Seneca County near Kansas. This tornado damaged a couple of buildings.

An EF0 tornado touched down southeast of Kansas just to the east of the intersection of State Route 636 and Township Road 36. The tornado was only briefly on the ground but tore the roof off of a mobile and damaged a nearby barn. A camper on property was also overturned. Many trees were also toppled and some corn was blown down in a field. The damage path was no more than 100 yards in length. A trained spotted witnessed the touchdown.

From NOAA NCEI's Storm Events Database, the narrative the local forecast office wrote for Storm Data.

The warnings

No tornado warning for this county appears in the archive as in force at the moment the tornado touched down. One was issued for the county at another hour that day.

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 00:53 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.
