Although heavy rain ended across Abbeville County during the morning, runoff from the earlier rainfall resulted in high water conditions persisting along streams in the northern part of the county, with multiple roads remaining flooded and closed into the afternoon.

Wider weather episode

A slow moving area of upper level low pressure over the Mid-Mississippi Valley pumped semi-tropical weather into the western Carolinas for a couple of days, resulting in occasional rounds of moderate to heavy in the day leading up to the 7th. Scattered slow-moving thunderstorm clusters developed during the morning of the 7th, producing torrential rainfall rates of 2 to 3 inches per hour and total rainfall amounts of 3 to 7 inches, much of which fell in just 2 to 3 hours. This excessive rainfall resulted in flash flooding of a number of creeks and other small streams in the Piedmont.
