VIDEO: FIRST ALERT: Part of Lowcountry under flash flood watch Wednesday

CHARLESTON, S.C. (WCSC) - Computer models show storms could dump up to three inches of rain or more over parts of the Tri-County area Wednesday.

Chief Meteorologist Bill Walsh says rainfall amounts will depend on a number of factors.

“A lot will depend on the speed of the low and where the moisture axis sets up," Walsh said. "All the models show pretty substantial rainfall totals for our area averaging from 2 to 4 inches. Bottom line, be ready for a wet Wednesday and some isolated flash flooding possible.”

Flash flood watch in effect until 6 p.m.

Portions of the Lowcountry are under a flash flood watch in effect through 6 p.m. Wednesday for Charleston, Berkeley, Dorchester, Colleton, Beaufort, Jasper and Hampton Counties.

Rainfall amounts of 2 to 5 inches will be possible with localized amounts over 6 inches. Although drought conditions remain in place for many areas, the rain could fall quick enough to produce runoff and flash flooding.
