At 5:10 p.m. on Saturday, the NWS reported a severe thunderstorm located near Graves, close to Georgetown, moving south at about 10 mph. The warning, updated by the NWS and in effect until 6:15 p.m., said the storm could produce nickel‑size hail (0.88 inches) and wind gusts up to 60 mph.
"At 5:10 p.m., a severe thunderstorm was located near Graves, or near Georgetown, moving south at 10 mph. Expect wind damage to trees and power lines."
The NWS named specific locations under the warning, including Georgetown, Yawkey South Island, North Santee, Sampit, Graves and Georgetown Memorial Hospital. The advisory urged residents to move to an interior room on the lowest floor of a building for protection and to report any hail or wind damage to the Wilmington NWS office.
What the warning means for residents
Severe thunderstorm warnings indicate that damaging winds, large hail or both are occurring or imminent in the warned area. According to the NWS message, residents should expect wind damage to trees and power lines. In such conditions, unsecured objects can become dangerous projectiles and travel can become hazardous.
- Forecast hazards: nickel‑size hail and wind gusts up to 60 mph (about 97 km/h).
- Immediate actions: seek interior shelter on the lowest floor away from windows; stay off corded phones and away from plumbing and electrical equipment if indoors.
- Reporting: the NWS asked for reports of hail or wind damage to help with situational awareness; a contact number for the Wilmington office was provided in the advisory.
Lightning, secondary hazards and preparedness
The NWS message also reiterated broader lightning safety guidance. Lightning strikes are most frequent during summer thunderstorms, and the agency estimated roughly 25 million strikes annually across the United States, with about 20 fatalities each year attributed to lightning.
Key safety tips repeated in the advisory include planning a route to shelter when heading outdoors, seeking shelter immediately when thunder is audible, avoiding contact with corded phones and plumbing while inside, and waiting 30 minutes after the last thunder or lightning before returning outdoors. If indoor shelter is not available, the NWS advised avoiding hilltops, open fields and lone trees and, if in a group, spreading out to reduce the risk of current travelling between people.
