Weather Disrupts Regional Infrastructure in Ohio and Northern Kentucky
What happened
A Flood Watch was in effect for parts of the Tri-State area on September 18, 2026, due to downpours. Crashes caused lanes to close on both sides of Interstate 75 near Downtown, leading to traffic backing up along the Brent Spence Bridge over the Ohio River into Northern Kentucky. Flash flooding was a concern in northern and eastern Cincinnati suburbs, and the Little Miami River in Warren County was expected to surpass flood stage.
