Lancaster Co EM reported Mount Carmel Rd flooded at Bayspring Rd.

The wider storm

An upper trough moved into the Southeast, acting as the main forcing in a strongly unstable environment with weak deep layer shear and high PWAT's. This forcing led to the development of scattered strong to severe convection that moved slowly due to the weak steering flow. The slow moving nature and efficient rainfall from these storms led to an area of flash flooding in Lancaster County, SC.

Began near Cauthens Xrds (34.6000, -80.7800).
