Overview

A series of thunderstorms caused widespread flash flooding across portions of Pike County on the evening of July 17, 2010. Initially, thunderstorms developed and moved into the area about 4 pm in the afternoon. Thereafter, thunderstorms redeveloped and moved repeatedly over the same locations, producing the flash flooding.

The National Weather Service Office in Jackson, Kentucky issued it's first flash flood warning at 7:57 pm as thunderstorms producing very heavy rainfall continued to move through central Pike County. Tragically, the flash flooding was directly, or indirectly responsible for 2 fatalities. Best estimates indicate that between 3 and 7 inches of rain fell across central portions of Pike County between 4 pm Saturday afternoon and 1 am Sunday morning, with the bulk of the rainfall occurring between 5 pm and 10 pm Saturday.

Radar estimated rainfall from 1 pm to 10 pm Saturday July 17, 2010

The greatest rainfall amount measured in a rain gauge during the event came from an observer on Lick Creek who measured 4.90" between 6:30 pm and 10 pm Saturday evening July 17th. A cooperative observer in Fedscreek reported 3.66 inches (24 hour amount as of 7am Sunday morning), and an IFLOWS gage at East Ridge High School recorded 4.36 inches over a three and a half hour period Saturday evening as well.
