EF1 tornado, Wooster, Ohio, November 5, 2017

This EF1 tornado ran 0.2 miles across Wayne County on November 5, 2017, touching down at 5:52 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 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.

What the Weather Service recorded

A cold front moved across the Ohio Valley and southern Great Lakes on the afternoon of Sunday, November 5th, 2017. Unseasonably warm and humid air was in place across the region ahead of the front. The cold front gradually progressed across the Ohio Valley and thunderstorms initiated and swept east ahead of the front. The storms formed in a very strong wind field and allowed the storms to move very rapidly east at speeds of 60 to 80 mph. A large macroburst formed and swept east just south of Cleveland and produced winds in excess of 100 mph. The most concentrated damage stretched from southern Lorain County across Cuyahoga County and into northern Summit, northern Portage and southern Geauga Counties. A 105 mph thunderstorm wind gust was measured at Aurora in Portage County. In addition to the damaging winds, at least 13 tornados were reported. Three of the tornadoes reached EF2 intensity with eight EF1 tornadoes and two EF0 tornadoes. Tens of thousands of trees were downed by these storms and widespread power outages occurred. In the Cleveland area alone, over 100,000 electric customers lost power. It took several days for power to be completely restored. Dozens of homes, buildings and barns were damaged or destroyed by the tornadoes.

An EF1 tornado touched down at the Secrest Arboretum on the south side of Wooster. The tornado tore half the roof off of the Frederick Rice historical home with debris thrown north-northwest through southeast. East of the home, trees were snapped and uprooted in a convergent pattern. A couple greenhouses were also damaged. This tornado was on the ground for less than a quarter mile and was no more than 50 yards in width.

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

The warnings

18 minutes of warning. NWS CLE issued a tornado warning for this county at 22:34 UTC, 18 minutes before the tornado touched down, in force until 23:00 UTC.

The county was under a tornado watch, issued at 17:10 UTC and running to 00:00 UTC.

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 19:59 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.
