Three tornadoes confirmed from the Aug. 11 storms touched down in Franklin and Madison counties, the National Weather Service's Wilmington office announced Aug. 27.

The findings reverse an earlier preliminary assessment that attributed damage near Upper Arlington solely to straight-line winds. An EF0 tornado east of Upper Arlington traveled 2.7 miles with peak winds of 80 mph, injuring two people. An Ohio Department of Transportation traffic camera captured the funnel crossing Interstate 71 at the Weber Road exit, flipping a single vehicle, according to the NWS damage survey.

Dublin was among the areas with the most widespread damage. The NWS identified Upper Arlington, Hilliard, Dublin and Reynoldsburg as the zones where damage was most extensive, though the agency attributed most destruction to straight-line winds of 60 to 80 mph, with isolated areas reaching 90 to 100 mph.

The Upper Arlington EF0 began near Kenny Road at about 10:05 a.m. Aug. 11. It crossed State Route 315 and the Olentangy River, damaged businesses on North High Street, then tracked east along Glen Echo Creek and U.S. Route 23 before crossing I-71. It dissipated near Beulah Road and East Weber Road in Grandview Heights three minutes later.

A stronger EF1 tornado struck the Olde Towne East neighborhood in Columbus at 10:08 a.m. the same morning. It traveled 1.3 miles with peak winds of 90 mph. One brick apartment building lost the roof and wall structure of its top floor on the west side, according to the NWS survey for that tornado. No one was injured.

A third tornado, an EF0, touched down southeast of Plain City in Madison County at 9:51 a.m., damaging trees and crops along Big Darby Creek and Amity Pike during its 1.2-mile, two-minute path.

The three new confirmations bring Ohio's 2026 tornado count to 44, 10TV reported, citing NWS data. Ohio recorded a record 74 tornadoes in 2024.

The NWS had already confirmed a separate EF1 tornado on Columbus' south side from the same Aug. 11 storms, near East Hinman Avenue and Parsons Avenue, where Lincoln Park's Barack Community Center lost its roof.

No tornado warning was ever issued for Franklin County that morning. Jeff Young, director of the Franklin County Emergency Management Agency, told 10TV on Aug. 12 that sirens activate only when the NWS issues a tornado warning. "We need to continue to spread the message that severe thunderstorm warnings and straight-line winds can carry the same punch," Young said in that interview.

The NWS noted all findings remain preliminary pending final publication in NWS Storm Data.

Franklin County Auditor Michael Stinziano is reminding homeowners that storm-damaged properties may qualify for a temporary reduction in assessed value. Applications for damage that occurred between July and September must be submitted by Dec. 31, according to the auditor's office.
