Cincinnati, Ohio – Slow-moving thunderstorms may drench southwest Ohio tonight, triggering flash flooding risks in Cincinnati and the broader Tri-State region between 10 p.m. Monday and 6 a.m. Tuesday.
According to the National Weather Service in Wilmington, heavy rain is expected across southern and central Ohio overnight, with the greatest flood threat centered in metro Cincinnati and surrounding counties. The flash flood risk could lead to road closures, especially in low-lying or poor-drainage areas.
Areas like Dayton, Hillsboro, and Portsmouth may also see localized flooding, with rainfall rates exceeding one inch per hour. Drivers are urged to avoid flooded roadways and check local alerts before heading out Tuesday morning.
Looking ahead, a more organized line of severe storms is possible late Wednesday into early Thursday, particularly along I-71 from Columbus to Cincinnati. The primary threats include damaging winds and large hail, with potential power outages and tree damage.
Residents should prepare for changing weather by securing outdoor items, charging devices, and staying tuned to local emergency alerts. Flash flood watches and severe weather outlooks may be updated through midweek.
