Flash Flood in York County, South Carolina

Law enforcement reported Jones Branch overflowed its banks in the Fort Mill Area after 4 to 5 inches of rain fell in just a couple of hours in association with a slow-moving cluster of thunderstorms. Harris Rd was inundated near I-77 by water from the creek. Additionally, media reported that a portion of I-77 was closed in this same area due to several feet of water inundating the roadway. It was not clear if this water was due to a tributary of Jones Branch overflowing its banks, or due to poor drainage.

Scattered thunderstorms and storm clusters developed across upstate South Carolina during the afternoon into the evening. A few of the storms produced brief strong-to-damaging wind gusts. In addition, the storms tended to move slowly, and one slow-moving storm cluster produced very heavy rainfall and flash flooding in York County.
