WHAT: Flash flooding caused by excessive rainfall is possible.
-
WHERE: Portions of northeast Georgia, including the following area, Rabun, western North Carolina, including the following areas, Avery, Buncombe, Burke Mountains, Caldwell Mountains, Graham, Haywood, Henderson, Macon, Madison, McDowell Mountains, Mitchell, Northern Jackson, Polk Mountains, Rutherford Mountains, Southern Jackson, Swain, Transylvania and Yancey, and upstate South Carolina, including the following areas, Greenville Mountains, Oconee Mountains and Pickens Mountains.
-
WHEN: From Wednesday morning through Friday afternoon.
-
IMPACTS: Excessive runoff may result in significant and damaging flooding of rivers, creeks, streams, and other low-lying and flood-prone locations. Areas that are not typically impacted by floodwaters may flood.
-
ADDITIONAL DETAILS:
- Multiple rounds of heavy rainfall are expected due to the interaction of tropical moisture along a stationary front, followed by the passage of Tropical Storm Helene. Storm-total rainfall of 8-12 inches is expected along the entire length of the Blue Ridge Escarpment with widespread 5-8 inches expected across the remainder of the mountains as well as the Piedmont. This has the potential to be an extremely rare event with significant and damaging flash-flooding along numerous streams.

A Flood Watch for flash flooding means there is a potential for rapid onset flooding based on current forecasts. Flash flooding is a very dangerous situation and may impact areas that do not typically flood. Please monitor the latest forecasts and be prepared to take action quickly should Flash Flood Warnings be issued. Rainfall of more than five inches in similar storms has been associated with an increased risk of landslides and rockslides. If you live on a mountainside or in a cove at the base of a mountain, especially near a stream, be ready to leave in advance of the storm or as quickly as possible should rising water, moving earth, or rocks threaten. Consider postponing travel along mountain roads during periods of heavy rainfall. Low-lying areas adjacent to streams, including campgrounds, are especially vulnerable to flooding. If you live or are vacationing next to a stream, please have a plan in place to seek higher ground once heavy rainfall develops. Flash floods can occur quickly and overwhelm adjacent low-lying areas with little warning. Once the stream starts to rise, you may only have minutes to evacuate. Flash floods can cause catastrophic damage and be powerful enough to sweep away campers, vehicles, and mobile homes. Consider temporarily relocating away from streams until the heavy rainfall threat passes.
