The storm damaged several buildings and flipped a car on I-71 as seen on an ODOT camera. Two people were injured during this tornado. A third EF1 tornado was confirmed in the Columbus area that day.

The National Weather Service has been surveying the damage from the two rounds of storms the morning and afternoon of Aug. 11.
The Storm Prediction Center says the second round of storms was officially classified as a derecho, which is a widespread, long-lived straight-line windstorm associated with a fast-moving band of severe thunderstorms. Damage from derechos are caused by straight-line winds instead of tornadoes. Some wind gusts near 100 mph were observed in central and eastern Ohio.
