The National Weather Service has confirmed that an EF1 tornado touched down in south Columbus during severe thunderstorms on the morning of Aug. 11, 2026, causing structural and tree damage along a short path while other nearby communities experienced high straight-line winds.
- The National Weather Service confirmed an EF1 tornado touched down in south Columbus on Aug. 11, 2026, with peak winds near 100 mph along a roughly 1.8-mile path.
- Damage in Upper Arlington from the same storm system was attributed to straight-line winds of about 90–100 mph, not a tornado.
- Officials declared state and mayoral emergencies; extensive power outages and structural damage were reported, and further NWS surveys are expected.
What the survey found
In a preliminary damage survey released Aug. 13–14, meteorologists from the NWS Wilmington office and Franklin County emergency management concluded the tornado began near East Hinman Avenue and tracked eastward across Parsons Avenue, Barack Park and as far as Fairwood Avenue. The bureau’s later update determined the tornado’s maximum winds reached about 100 mph along a path approximately 1.8 miles long and 100 yards wide, which is consistent with an EF1 rating on the Enhanced Fujita scale.
The survey team documented convergent damage in south Columbus — debris and trees falling toward the storm’s path — and reported roof damage to some homes and businesses, including the Barack Community Center and multiple commercial properties.
How Upper Arlington and other nearby areas were affected
Survey crews also examined damage in Upper Arlington and near Upper Arlington High School. There, investigators found a different pattern: trees and property damage showed no visible signs of tornadic circulation or convergent debris patterns. Instead, the NWS attributed those impacts to straight-line winds estimated between 90 and 100 mph.
The distinction matters for both records and recovery. As the NWS explained through local outlets, a convergent pattern — where debris turns back toward the track — helps confirm rotation on the ground and supports a tornado determination. Where that signature is absent, strong straight-line winds are a more likely cause.
Local impacts and response
Tuesday’s storms produced widespread, severe impacts across central Ohio. Local TV reports and news coverage documented extensive property damage, downed trees and overturned vehicles; traffic camera footage circulated showing a tornadic-looking circulation crossing Interstate 71 and flipping a car near the Weber Road area.
Power outages were widespread. Initial reporting estimated outages affecting roughly 100,000 customers in the Columbus area during the day; as of two days after the storms, more than 25,000 Franklin County residents remained without power. Governor Mike DeWine issued a proclamation declaring Franklin County under a state of emergency, and Columbus Mayor Andrew Ginther declared a mayoral emergency and asked the community to assist recovery efforts on the city’s south side.
Where this fits in recent local tornado history
The NWS noted this is the first EF1 to touch down in Franklin County since a predawn EF1 that moved from Brown Township into Hilliard on Feb. 28, 2024. The agency also referenced an EF0 tornado reported in Obetz on Mar. 30, 2025.
Outstanding questions and next steps
The NWS characterized its Aug. 13–14 findings as preliminary and said additional storm surveys were planned to better define wind-damage corridors across central Ohio. A final, more detailed assessment of the tornado’s track and intensity is expected in the coming days, according to local reports summarizing the NWS statements.
Officials continue cleanup and restoration work. Authorities have not released public casualty figures in the preliminary survey summaries cited by local outlets; the scope of insured and uninsured property losses is still being assessed.
Context and practical implications for residents
Meteorologists pointed out that the broader outbreak produced both rotating tornadoes and damaging straight-line winds across the Midwest on Aug. 11, with other regions — including parts of the Chicago area — also reporting tornado warnings, very high wind gusts and extensive outages. Local emergency managers emphasize preparedness for both tornadoes and severe straight-line wind events because damage signatures can differ and warnings may not always precede on-the-ground effects.
For Columbus residents, the immediate tasks are cleanup, power restoration and rebuilding damaged structures, particularly in the affected south-side neighborhoods. Officials have asked residents to avoid unstable structures, report downed power lines to utilities, and follow guidance from city and county emergency management as recovery moves forward.
