The tornado crossed Highway 21 and produced damage in areas including Walnut Street, Hampton Street, Duke Street, and Republic Street. Estimated winds were up to 105 mph in Chester County, based on large trees being uprooted or snapped. In addition, a house on Republic Street was destroyed when a tree fell on it. The tornado strengthened as it crossed the Catawba River and entered southwestern Lancaster County. The tornado moved southeast, producing significant tree damage, with numerous large hardwood and softwood trees uprooted or snapped. The most significant damage occurred between Green Road and Cedar Creek Road near Mount Carmel Road, where estimated winds were up to 115 mph. A tree also fell on a vehicle on Cedar Creek Road.

A very strong downburst and associated gustnado occurred just east of the town of Kershaw along Arbor Road, just before Woodhaven Road. While much of the damage was based on straight line winds, there was evidence of an embedded gustnado causing some of the damage based on the tree fall pattern. The damage was primarily to trees between Arbor and Woodhaven Roads, with many trees uprooted and some snapped. Gustnados are small whirlwinds that form on the edge of thunderstorm outflow winds. They do not connect with any cloud base rotations, and are not tornadoes, but can cause damage. * The information in this statement is preliminary and subject to change pending final review of the event and publication in NWS Storm Data.

Minor to moderate river flooding occurred along the the Great Pee Dee River at Cheraw, the Enoree River at Whitmire, the Saluda River at Chappells, the Congaree River at Columbia...Carolina Eastman and the Congaree National Park at Gadsden, Lake Wateree and the Wateree River at Camden.
