The Live 5 Weather team declared Monday a First Alert Weather Day with impacts expected from a possible tropical cyclone off the Carolina coast.
The National Weather Service will issue a Flash Flood watch for Georgetown and Horry Counties from 2 p.m. Monday through Tuesday morning. Heavy rainfall will lead to ponding water or road closures. Up to three to six inches of rain is expected within most of the watch area with localized higher amounts possible.
Early Sunday, The National Hurricane Center issued a tropical storm watch from the South Santee River in South Carolina to Duck, North Carolina, an area that includes Georgetown and Horry Counties. The watch also includes Albemarle Sound and Pamlico Sound.
Georgetown County increased its status to OPCON 4 as of 8 a.m. Monday as it prepares for impacts from potential Tropical Cyclone Ten.
As of 8 a.m., the system was approximately 135 miles south-southwest of Charleston and 280 miles southwest of Wilmington, North Carolina. The maximum sustained winds were holding at 35 mph.
Live 5 Meteorologist Joey Sovine said upper-level winds have been shearing the system apart were continuing to do so Monday morning.
“We could get a minor tropical system,” Sovine said. “We are starting to see development.”
The system will become Tropical Storm Irma when maximum sustained winds reach a speed of 39 mph. He said the system could form into either Tropical Storm Irma or Subtropical Storm Irma by 11 a.m.
The system has begun to move northward and will accelerate Monday afternoon and Monday night.
The system is expected to produce total rain accumulations of three to six inches along the upper South Carolina, North Carolina, and southeast Virginia coasts, with possible isolated maximum amounts of nine inches. The heavier rains may result in some flooding concerns along coastal areas north of Charleston.
“We can expect windy conditions along the coast with high seas and dangerous rip currents,” Sovine said.
