Tropical Storm Cindy made landfall in southwestern Louisiana on the 22nd. The storm weakened after making landfall and became post tropical as it moved through the Mississippi and lower Ohio River Valleys into the 23rd. At the same time, a strong cold front was moving eastward across the Midwest and western Great Lakes. The remnants of Cindy passed through the eastern portions of the Ohio River Basin during the evening of the 23rd. The tropical moisture and energy associated with the remnants combined with the lift of the approaching cold front to produce a large area of heavy rainfall. The area of the heaviest rain stretched along the Middle Ohio River Valley, from central and northeastern Kentucky into southeastern Ohio and western West Virginia.
Common rainfall measurements ranged from 2 to 3 inches across Southeast Ohio. For example, in Athens County the Nelsonville cooperative observer measured 2.6 inches of rain, while a CoCoRaHS observer in nearby Chauncey reported 2.8 inches. In Meigs County, the cooperative observer near Salem Center received 2.08 inches of rain, and the Newport observer in Washington County had 2.18 inches in their rain gauge.
Initially, flash flooding closed many roads across Southeast Ohio. Some areas of high water lingering through the 24th as water drained through the river system. Strong rises were seen on local stream gauges such as the Duck Creek at Whipple and the Little Muskingum River at Bloomfield in Washington County. In general, the Ohio River rose about 10 feet, however no river flooding occurred along the Ohio River.
