While most of the state was rain free, a late evening thunderstorm over Florence left 0.70 inches of rain. On Tuesday morning, Lake City and Georgetown cooled to 62 degrees. A few coastal thunderstorms developed during the middle of the day. One-inch hail fell for almost thirty minutes near the Sampit community. At 6:41 p.m., National Weather Service instruments at Pineville measured a thunderstorm wind gust of 59 mph.

During the day, the outermost rain bands of Tropical Storm Beryl began rotating northward into the Lowcountry. The Beaufort Marine Corps Air Station measured 0.48 inches in a passing shower.
