What happened

The episode as NWS CHS wrote it up.

A large area of stratiform rain spread across the southeast South Carolina in the predawn hours ahead of a warm front lifting northward. Immediately along the warm front, embedded thunderstorms developed and brought a period of strong wind gusts and intense rainfall to the region. A large area of heavy rainfall, with amounts of 2-4 inches, occurred from around Beaufort up through the Charleston metro area. Locally higher amounts of up to 5 inches occurred in and around Charleston, with the heaviest rainfall rates occurring around and just after a 7.69 ft MLLW high tide at the Charleston Harbor tide gauge. The intense rainfall produced a few instances of flash flooding around Charleston, with lots of reports of minor flooding.
