Clark County Flood History

Flash Flood — Jul 30, 2021

Scattered thunderstorms, ahead of a could front, drifted south through southern Indiana and the Bluegrass region of Kentucky in an unstable environment. Some of these storms became severe causing isolated tree damage and flash flooding in Kentucky counties. The most severe flooding was in Carlisle, Kentucky after heavy rainfall continued falling over the same area. Several buildings and vehicle...

Flash Flood — Oct 7, 2021

Central Kentucky was located in the warm sector ahead of a surface low to the west, a west to east oriented warm front to the north, and a north to south oriented cold front to the southwest. Moderate instability and shear from strong southern flow took advantage of the added Gulf of Mexico moisture. This produced thunderstorms that caused isolated severe wind damage and flash flooding over the...

Flash Flood — May 19, 2020

May 18, the Lower Ohio Valley was primed with a moist atmosphere that was in place from southerly surface flow from the Gulf of Mexico, and as a cold front moved through the region, severe thunderstorms caused tree damage and isolated flooding. On the 19th, the flooding became more widespread as heavy rain was produced from outflow boundaries remaining in the region from the previous day's storms.

Flash Flood — Sep 9, 2018

On September 5, 2018, the remnants of Tropical Storm Gordon moved north from the Gulf of Mexico. It carried copious amounts of moisture as it continued to rotate while slowly moving north. In Kentucky, the outer bands of the system brought showers and thunderstorms that produced isolated wind damage September 5 and 6. By September 8th, Gordon was centered in southeast Missouri with much of i...
