Severe Flooding Across Parts of Northeast Kentucky
and Southern Ohio
July 20-21, 2010
A frontal boundary stalled just south of the Ohio
River on Tuesday, allowing for several waves of showers and
thunderstorms across southern Ohio and northern Kentucky. Very
high moisture was in place, which made these storms efficient heavy rain
producers. These storms tracked repeatedly over the same
locations, with some areas receiving heavy rain for almost 4 consecutive
hours Tuesday night. This led to very high rainfall amounts.
The highest amounts were across Mason and Lewis counties where rainfall
amounts of 7 to 9 inches fell in just a few hours.
This extreme amount of rainfall led to very serious flooding across
Mason, Lewis and Scioto counties. Countless water rescues occurred
due to people trapped on the roofs of their homes and cars due to very
rapidly rising water. Dozens of buildings in Lewis and Scioto
counties sustained heavy damage. Several structures in Lewis County
were swept completely off their foundations, including a grocery store
in the central part of the county. One fatality occurred near
Franklin Furnace in Scioto County, when a woman was swept away by
rushing flood waters.
