First floor apartments were flooded and vehicles were swallowed by high waters after 5.91 inches fell in Louisville on Saturday alone, according to the Weather Channel.
"I was lying there sleeping, kids woke me up, looked out, I couldn't believe it," evacuee Vickie Dedrick told NBC affiliate WAVE in Louisville.
"Just a little bit of water on the road, next thing you know it looks like a tidal wave come through; looks like all cars washed off," added evacuee Mark Elliott.
No injuries were reported, but at least 45 roads were closed and many homes and cars were damaged, according to the Courier-Journal.
