SOUTH CAROLINA WEATHER AND CLIMATE
July 21-27, 1997
WEATHER SUMMARY
After a sunny start Monday, cloudy skies along a nearly stationary
boundary returned and persisted into mid-week. On Wednesday, July 23, a
tropical low, which as Hurricane Danny had come ashore in Alabama, brought
flooding rains and tornadoes to South Carolina. Hardest hit were the
central midlands where unofficial rainfall totals exceeded 8 inches. A
brief, violent tornado touched down near Gaston in Lexington County,
destroying several mobile homes, causing one death and multiple injuries.
Tornadoes were also reported in east Richland and Abbeville counties. Many
sites reported damage from high winds. Most small streams and creeks in
the affected areas could not handle the heavy rains. Street flooding
forced business closures and abandoning of autos. Since most South Carolina
river stages were below normal prior to the tropical rains, only a few
reached flooding conditions. Hot and humid followed the remainder of the
week. Aternoon temperatures climbed into the mid 90's. On Sunday both
Florence and Columbia observed a Heat Index value of 110 degrees.
Statewide temperatures for the period averaged near normal across the
coast and upstate and 2 degrees above normal in the midlands.
