Residents along the Whitewater River in Hamilton and Dearborn counties face significant flood risks, with evacuations already underway. Heavy rainfall from slow-moving storms could lead to flash flooding, particularly in areas that have already experienced substantial precipitation. The risk of damaging wind gusts, isolated large hail, and even a brief tornado cannot be ruled out. Additionally, the weekend's high heat and humidity may pose health risks, especially for vulnerable populations, as heat indices approach dangerous levels.
