Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
945 PM EDT MON AUG 14 2017
The National Weather Service in Greenville-Spartanburg has issued a
* Flash Flood Warning for...
Northern Habersham County in northeastern Georgia...
Southwestern Rabun County in northeastern Georgia...
* Until 345 AM EDT
* At 945 PM EDT, Doppler radar indicated thunderstorms producing
heavy rain across the warned area. 2 to 4 inches of rain has fallen
over the past 2 to 3 hours. Additional storms are moving into
Habersham and Rabun counties from the south and east. These storms
will be capable of producing another 1 to 3 inches of rainfall,
exacerbating any ongoing flooding and causing additional flooding
to develop. Residents and travelers are urged to exercise
extreme caution over the next several hours.
* Some locations that will experience flooding include...
Lake Rabun, Lake Burton, Lakemont, Seed Lake, Batesville, Tallulah
Falls and Tallulah Gorge State Park.
* The following streams are experiencing rapid rises and minor to
moderate flooding is possible: In Rabun County, Tiger Creek,
Sawmill Creek, Slick Shoal Creek, Worley Creek, Pole Bridge Creek
and other tributaries into and including the Tallulah River. In
Habersham County, Right Fork Soquee River, Raper Creek, and other
tributaries into and including Soquee River.
PRECAUTIONARY/PREPAREDNESS ACTIONS...
In hilly and mountainous terrain, there are hundreds of low-water
crossings which can be dangerous in heavy rain. Low-water crossings
can be submerged by flood waters quickly and without warning. Never
attempt to travel across flooded crossings. Find an alternate route.
It takes only a few inches of swiftly flowing water to carry vehicles
away.
Runoff from heavy rain into creeks and streams will cause sudden
increases in water levels and flows, even in areas where rainfall has
been light or nonexistent. Hikers, campers, kayakers, and other
individuals outdoors must immediately seek high ground and avoid all
streams.
When it is safe to do so, please report flood waters or landslides
flowing over roads or threatening property to the National Weather
Service by calling toll free, 1, 800, 2 6 7, 8 1 0 1, by posting on
our Facebook page, or via Twitter using hashtag NWSGSP.
