Significant flash flooding developed across portions of eastern Kentucky during the late afternoon and evening hours of August 22nd into the early morning hours of August 23rd. Clusters of slow moving thunderstorms moved repeatedly across the areas of Johnson, Floyd, Pike, and Martin counties. Other counties that experienced flooding were Montgomery, Powell, Wolfe, and Estill counties. The most widespread and devastating flooding, however, occurred across portions of Johnson, Floyd, and Pike counties. Floyd county was hit the hardest, particularly in a small section of north central Floyd where around 4 inches of rain fell in less than two hours. The flooding washed out roads in Estill, Floyd, and Johnson counties. At one point during the evening of August 22nd, numerous areas in and around Prestonsburg were completely under water with multiple cars and buildings surrounded by water at times. In general, 2 to 4 inches of rain fell in 90 minute to two hour period across Johnson, Floyd, and Pike counties, which lead to excessive runoff that quickly brought creeks and streams out of their banks and roadside culverts and storms drains to quickly overflow into adjacent roadways.
