The Beaufort County Sheriff’s Office has also urged caution when driving through Burton as there is high water in multiple areas. Currently, Broad River Boulevard and County Shed Road are affected.

According to the NWS, between 3 and 5 inches of rain have fallen in the area, and the region can expect an additional 1 to 3 inches in the coming hours. Areas with poor drainage and low-lying areas are most likely to be affected by flash flooding.

Thunderstorms and rain showers will continue through the evening hours, though the flash flood warning will end at 5:45 p.m.
