WLWT reported Tuesday that Clermont County was under a Tornado Warning until 3:15 p.m. as strong to severe thunderstorms moved into the region. Grant, Carroll, Owenton and Gallatin counties were under the same warning until 3:45 p.m., putting several counties on alert at once.
The Storm Prediction Center placed much of the area under an Enhanced Risk, Level 3 of 5, and Tuesday was described as a First Alert Weather Day. A Severe Thunderstorm Watch covered the entire Tri-State Area until 8 p.m., while a Flash Flood Warning covered Dearborn and Hamilton counties until 5:45 p.m.
Clermont County and nearby counties
Residents in Clermont were working under a shorter warning window than people in Grant, Carroll, Owenton and Gallatin counties. That kind of split timing means the most dangerous weather did not arrive everywhere at once, and the exact warning time depended on where the storms were tracking.
The greatest threat window ran from around noon through 5 p.m. Damaging straight-line winds were the most significant threat, and heavy rainfall was a particular concern where storms repeatedly moved over the same locations.
Tri-State Area watch
The Severe Thunderstorm Watch until 8 p.m. kept the broader Tri-State Area under a wider alert even as individual tornado warnings had different end times. That left the afternoon and early evening as the main period for fast-changing conditions across multiple counties.
Dearborn and Hamilton counties also had a Flash Flood Warning until 5:45 p.m., which pointed to runoff and repeated rainfall in the same areas rather than just brief passing storms. For readers in warned counties, the immediate step was to stay alert to changing notices, because the strongest storms were expected during the afternoon window.
Later tonight in Cincinnati
Storms were expected to gradually weaken later tonight and move out of the area by Wednesday morning. A stray sprinkle was possible Wednesday, but most neighborhoods were expected to stay dry, with noticeably cooler and less humid air moving in after the storms.
