Full official description

Bulletin details

* WHAT...Flooding caused by excessive rainfall is expected. * WHERE...Northern Greenville County in upstate South Carolina... Northern Pickens County in upstate South Carolina... * WHEN...Until 930 AM EDT Sunday. * IMPACTS...Nuisance flooding of low-lying areas adjacent to streams and other poor-drainage areas, including farmland, parks, greenways, boat-access areas, golf courses, underpasses, and parking lots. Isolated, shallow flows over roadways is possible. A few flood-prone, low-water crossings may become impassible. A small culvert washout or two is possible. * ADDITIONAL DETAILS... At 932 PM EDT, Doppler radar indicated a line of torrential rainfall quickly moving from south to north across northern Pickens and Greenville counties. This rainfall is occurring on top of saturated soils due to a prolonged period of light to moderate showers that have occurred over the county since this morning. Widespread, storm-total rainfall of the 2.5-3.5 inches have fallen over the past 12 hours. The rainfall has accumulated steadily, allowing soils to slowly saturate and runoff to slowly increase, resulting in steady rises in small streams. However, this brief period of torrential rainfall is causing more rapid rises to develop, including along Eastatoe Creek near Rocky Bottom and Sunset, Oolenoy River from Sunset to Pumpkintown, Middle Saluda River from Jones Gap State Park to Cleveland, North Saluda River above the reservoir and below the reservoir near Slater- Marietta, and the headwaters of the South, Middle, and North Tyger rivers from Tigerville to Gowensville. Isolated to scattered out-of-bank conditions impacting low-lying areas adjacent to streams are likely to develop over the next 1-3 hours. Additional rounds of showers and thunderstorms may develop over tonight and the threat will persist through the early morning hours on Sunday. These showers and storms will be very efficient at producing heavy rainfall. Soils are saturated and streams are swollen. Therefore, additional heavy rain may quickly create new areas of flooding and cause previous areas of flooding to redevelop. As a result, Flash Flood Warnings may be issued tonight. Caution is advised near any stream or other vulnerable area. Seek higher ground immediately if heavy rain develops. Please have a plan in place should flash flooding develop and do not hesitate to act. Please heed all evacuation orders from Emergency Management officials. Some locations that may experience flooding include... Travelers Rest, Slater-Marietta, Tryon, Pleasant Ridge State Park, Jones Gap State Park, Caesars Head State Park, Table Rock State Park, Tigerville, Jocassee Gorges, and Keowee Toxaway State Park. http://www.weather.gov/safety/flood
