Storm total rainfall of 5 to 7 inches is expected across much of the Watch area over a 24 to 30 hour period. A few locations could see totals approach or exceed 9 inches. * This amount of rain will produce areas of flash flooding along smaller streams, creeks, and in urban areas. Rain bands producing torrential rainfall rates may result in localized amounts around 9 inches and significant flash flooding. In addition to flash flooding, at least minor main stem river flooding is likely, especially along the Saluda River in Upstate South Carolina. PRECAUTIONARY/PREPAREDNESS ACTIONS... A Flash Flood Watch 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.
