Update: Friday downpours may flood local roadways

July 4, 2013 

— Local downpours Friday in Lexington and Richland counties have prompted the National Weather Service to advise motorists and others that streams and creeks in the area could flood.

US 321 in Gaston reportedly already has flooded, the weather service said.

The advisory also includes northern Calhoun County and is set to expire at 3 p.m.

Officals caution that motorists should avoid driving on flooded roadways. If you encounter a flooded area, you should contact the county sheriff’s department when it is safe to do so, or report it on the weather service’s Facebook page.

Meanwhile, a more general flood advisory specific to the Congaree River in Lexington and Richland counties continues through Saturday.

The National Weather Service issued the update at 8:40 p.m. Thursday, stating that recent heavy rain and reservoir releases are causing higher levels on the Congaree River.

The advisory specifically characterizes the event as “nuisance flooding” near the river below official flood stage.

At 8 p.m. Thursday, the river was at 8.8 feet. Flood stage is 19 feet and advisories are issued when the river’s flood stage reaches 10 feet. The river is forecast to crest around 11 feet.

The lowest section of the Cayce-West Columbia Riverwalk begins to flood around 9 feet.
