Flooding stranded motorists around Kellogg Avenue and Sutton Road near Coney island as crews made rescues of at least six different vehicles. The Fort Thomas exit off I-471 was closed and travel across the Brent Spence Bridge was especially slow due to flooding.
By 6 a.m., about 1,600 Duke Energy customers were without power, with the majority centered around Fayetteville (Brown County) and Midland (Clinton County).
