The same area that we have been monitoring for tropical development now has a low-pressure system that is bringing rounds of showers and storms to the Pee Dee and dangerous seas across the South Carolina Coast.
The low-pressure system will continue to organize and head toward the Carolinas. There isn't a lot of time for this system to develop. As of Sunday afternoon, the National Hurricane Center gives it a 50 percent chance to develop. Regardless of development, the northern portion of South Carolina can expect heavy rainfall that can lead to flash floods.
When and how much rain?
There will be heavier rounds of showers starting Sunday night as the storm spins offshore during the start of the work week and it starts to move toward the Carolinas. Expect heavy rains to fall over the coast, east of I-95 through Tuesday.
Flood watches are in effect for Horry, Marion, and Dillon counties through Tuesday morning.
The heaviest rainfall will be focused over coastal Pee Dee where rainfall during the next 5 days could range between 8 to 10 inches, and some isolated spots could reach 12 inches. The Midlands could receive between 2 and 4 inches and up to 6 inches in some isolated spots. Keep away from flooded roads. Turn around, don't drown. Remember that if there is any deviation of the center of the storm, there will be chances to the locations where the heaviest rain would fall. If it shifts a bit more south, then there would be heaviest amounts falling over the Pee Dee and Midlands. If the system were to move a bit more north, then fewer amounts would fall over the northern portion of South Carolina.
Swimmers and boaters are asked to please stay off the water. Seas will be rough as waves will be large and there is the risk of powerful rip currents. We are closely monitoring the evolution of the low-pressure system and will continue to bring you updates.
