A frontal system was draped across the central Appalachians on the 10th and 11th. As waves moved along the front, periods of heavy rainfall moved across southern West Virginia. Rainfall started during the morning of the 10th, with the heaviest rain from late afternoon overnight into the 11th. The most rain fell across portions of Mingo, McDowell, Wyoming, Logan and Raleigh Counties, where 2-3 inches of rain fell with many roads closed due to flooding. The cooperative observer at Oceana in Wyoming County measured 2.56 inches of rain, and at R.D. Bailey Lake on the Wyoming/Mingo border, 2.37 inches was measured. The cooperative observer at Man in Logan County measured 2.2, while the VA Hospital in Beckley got 2.09 inches of rain. Farther north generally 1-2 inches of rain fell, which still caused some minor problems due to saturated ground.
As the water drained through the creeks and streams, several rivers also flooded.
