Tornado Threat Moves Across Kentucky and Ohio
A dangerous weather situation is unfolding across the Greater Cincinnati and Northern Kentucky region on Tuesday, August 11, 2026, with a Tornado Warning affecting Boone County, Campbell County, and Kenton County in Kentucky, along with Clermont County and Hamilton County in Ohio.
The National Weather Service’s Wilmington office has issued tornado-related warnings for the Cincinnati-area region as severe thunderstorms move through. A later warning for Hamilton County indicated a severe thunderstorm capable of producing a tornado near Cheviot, moving southeast at approximately 50 mph.
Areas Under the Tornado Warning
Residents in the following counties should take the warning seriously:
- Boone County, Kentucky
- Campbell County, Kentucky
- Kenton County, Kentucky
- Clermont County, Ohio
- Hamilton County, Ohio
These counties span the heavily populated Cincinnati metropolitan area and Northern Kentucky. The Wilmington National Weather Service office is responsible for warning operations covering this portion of the region.
Tornado Safety: Take Shelter Immediately
If you are inside the warned area, do not wait to see the tornado.
Move immediately to a basement or a small interior room on the lowest floor of a sturdy building. Stay away from windows and exterior walls.
Protect your head and neck with your arms, a helmet, or sturdy blankets and cushions.
If you are in a mobile home, vehicle, or other unsafe structure, move to a sturdy shelter if you can do so safely before the storm becomes dangerous.
If You Are Driving
Avoid driving directly toward the storm. If possible, get inside a sturdy building. Never shelter underneath an overpass, where winds can become especially dangerous.
If you cannot reach a building, pull over safely and remain buckled in the vehicle while assessing the safest available option.
Strong Winds, Hail and Flash Flooding Are Also Possible
Tornado-producing thunderstorms can bring additional hazards, including damaging straight-line winds, large hail, intense rainfall and dangerous lightning.
Heavy rainfall may also create rapid water accumulation, particularly in low-lying areas and locations with poor drainage.
Never drive through a flooded roadway. Even relatively shallow moving water can sweep vehicles off the road.
Cincinnati and Northern Kentucky Residents Should Stay Alert
The Cincinnati metropolitan area sits directly along the Ohio River, with communities in Hamilton, Clermont, Boone, Campbell and Kenton counties closely connected across the region.
That means severe weather can move across county and state lines quickly. A storm affecting one part of the Tri-State area can reach another community within minutes.
Keep weather alerts enabled on your phone and continue monitoring trusted weather sources until the warning has expired or is canceled.
What to Do After the Tornado Warning Ends
Do not immediately leave your shelter when the warning expires if dangerous storms remain nearby.
Check for:
- Downed power lines
- Gas leaks
- Structural damage
- Broken glass
- Fallen trees
- Blocked roads
- Additional severe weather warnings
Treat every downed power line as energized and stay away from it.
Stay Weather-Ready Across the Tri-State
The August 11 severe weather threat is another reminder that summer thunderstorms can rapidly become dangerous across Kentucky and Ohio.
For residents of Boone, Campbell, Kenton, Clermont and Hamilton counties, the safest response to a Tornado Warning is simple: get inside, get low and protect your head and neck.
