With many locations receiving above normal rainfall for the month, flash flooding occurred on the 17th, 23rd, 24th and 27th of July. July 17th...A nearly stationary surface boundary and moist atmosphere led to locally heavy rainfall and areas of flooding. The RCWINDS Mesonet site at Spring Valley High School reported 2.88 inches of rain in 30 minutes, then 3.98 inches in 1 hour with a total of 4.69 inches for the day. The heavy rainfall led to multiple vehicles stranded in flash flooding in the area of Two Notch Road and the Village of Sandhill in northeast Columbia.

Slow moving thunderstorms produced locally heavy rainfall that produced flooding in Richland and Chesterfield counties. In Chesterfield county near Mt. Croghan, heavy rainfall caused a pond to overflow and washed out portions of Gillmore Road. The rainfall also produced flooding in downtown Columbia as Rocky Branch Creek and Smith Branch Creek went above flood stage. A person had to be rescued from a vehicle at the intersection of Whaley Street and Main Street as the car was nearly submerged in flood waters. Gills Creek rose to near bankfull as well. Rocky Branch Creek at Whaley crested at 12.15 ft, the third highest since the gage was installed, flood stage is 7.2 feet.

A NWS employee reported 2.71 inches of rain in 1 hours in the Red Bank area. A car stalled on Senate Street due to the roadway being flooded. July 27th...Slow moving thunderstorms combined with a very moist airmass produced locally heavy rain in portions of the Central Savannah River Area just north of Augusta. This produced flash flooding that pushed Reed Creek out of its banks flooding portions of the Martinez area. Water from the creek lifted a vehicle and pushed it into a home.
