BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
1257 AM EDT Fri Mar 26 2021

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Habersham County in northeastern Georgia...
  Rabun County in northeastern Georgia...

* Until 645 AM EDT.

* At 1257 AM EDT, Doppler Radar indicates an axis of strong 
  thunderstorms with heavy rainfall entering Rabun and Habersham 
  counties.  These thunderstorms will be capable of producing 1-2 
  inches of rain in a very short period of time.  This rainfall will 
  occur on top of earlier rainfall of 3 to 6 inches across the 
  warned area and Minor flooding is already ongoing.  Therefore, 
  this new area of heavy rain will exacerbate ongoing flooding and 
  cause new areas of flash flooding to develop, some of which will 
  be significant.  This rainfall may also result in additional dam 
  releases along the Tallulah River, which may cause flooding 
  immediately downstream of area dams, including Mathis Dam near 
  Lakemont.

  HAZARD...Life threatening flash flooding. Thunderstorms
           producing flash flooding.

  SOURCE...Radar.

  IMPACT...Life threatening flash flooding of creeks and streams,
           urban areas, highways, streets and underpasses.
           Significant flooding of low-lying areas including
           farmland, campgrounds, low-water crossings, parks and
           greenways, residential yards, and other low-lying
           areas.  A few structures may also be impacted,
           including homes and businesses, requiring evacuations.

* Some locations that may experience flash flooding include...
  Clayton, Clarkesville, Demorest, Mountain City, Tiger, Dillard, 
  Sky Valley, Tallulah Falls, Lakemont, Lake Rabun, Lake Burton, 
  Tallulah Gorge State Park, Black Rock Mountain State Park, Seed 
  Lake, Turnerville, Hollywood, Batesville and Pine Mountain.

Residents downstream of Mathis Dam including near Shady Ln and along 
Old US 441 near Lakemont are urged to stay weather aware tonight and 
be prepared to seek higher ground at any time should additional dam 
releases occur.  This is a rapidly evolving situation.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.

Move to higher ground now. Act quickly to protect your life.

Be especially cautious at night when it is harder to recognize the 
dangers of flooding.
