FLASH FLOOD WARNING
The Sumter Item is hearing of reports of localized flooding on roadways. Do not drive through a road that has standing or moving water.
Sumter County and the surrounding area is under a flash flood watch from Thursday through Friday morning and a flash flood warning until 3:15 p.m. Thursday. Clarendon County is included in the warning.
Some locations that will experience flash flooding include Columbia, Sumter, Camden, Bishopville, Shaw Air Force Base, South Sumter, Elgin, Sumter County Airport, Mulberry, Millwood, Oakland, Elliott, Lee State Park, Goodale State Park, Lugoff, Woods Bay State Park, Turbeville, Mayesville and Lynchburg.
As the remnants of Hurricane Sally, which has been downgraded to a tropical depression as it moves inland from the Gulf Coast, the system is expected to spread rain across Georgia and South Carolina before it heads offshore of the Carolinas by Friday evening.
According to the National Weather Service, 4-7 inches of rain are expected across the region with “locally higher amounts in much of South Carolina and eastern Georgia.”
The NWS in Columbia predicts Sumter and Lee counties stand to take in 3-4 inches, while Columbia and Camden will receive 4-6 inches and Manning 2-3 inches.
The main areas of concern for flash flooding are along smaller streams, creeks and in urban areas.
Heavy rain in Sumter is expected Thursday and Thursday night, and forecasts say to be prepared for storms through Saturday afternoon.
TORNADO WATCH
Sumter, Clarendon and Lee counties as well as the surrounding Midlands and Upstate are under a tornado watch until 6 p.m. Thursday.
WHAT’S THE DIFFERENCE BETWEEN A WATCH AND A WARNING ISSUED BY THE NATIONAL WEATHER SERVICE?
Tornado Watch: Be Prepared. Tornadoes are possible in and near the watch area. Review and discuss your emergency plans and check supplies and your safe room. Be ready to act quickly if a warning is issued or you suspect a tornado is approaching. Watches are issued by the Storm Prediction Center for counties where tornadoes may occur. The watch area is typically large, covering numerous counties or even states.
Tornado Warning: Take Action. A tornado has been sighted or indicated by weather radar. There is imminent danger to life and property. Move to an interior room on the lowest floor of a sturdy building. Avoid windows. If in a mobile home, a vehicle or outdoors, move to the closest substantial shelter and protect yourself from flying debris. Warnings are issued by your local forecast office. Warnings typically encompass a much smaller area (around the size of a city or small county) that may be impacted by a tornado identified by a forecaster on radar or by a trained spotter/law enforcement who is watching the storm.
