649 PM EDT Thu Oct 7 2021

The National Weather Service in Greenville-Spartanburg has extended 
the

* Flood Warning for...
  Northwestern Elbert County in northeastern Georgia...
  Southwestern Hart County in northeastern Georgia...

* Until 800 PM EDT Friday.

* At 649 PM EDT, The USGS streamgauge along Beaverdam Creek at 
  Brewers Mill Rd is currently at 13.05 feet and steady, which is 
  above the Moderate Flood Stage of 12.00 feet.  This follows an 
  earlier crest of 16.53 feet, which occurred on Thursday at 9:00am 
  and was above the Major Flood Stage of 15.00 feet.

* Beaverdam Creek continues to cause unusual, significant flooding 
  of adjacent low-lying areas from Vanna to Bowman to Dewy Rose to 
  northern Elberton.  Several low-water crossings are still 
  inundated by up to 2-4 feet of floodwaters, including Winns Mill 
  Rd, Brickyard Rd, and Horse Farm Rd.  Floodwaters may also still 
  be impacting Brewers Mill Rd, Pulliam Mill Rd, and Vanna Rd.  
  Structures adjacent to Beaverdam Creek may also continue to be 
  threatened at these levels, including the former Red Minnow 
  Restaurant.

* Drivers are urged to avoid flooded roadways especially because 
  these floodwaters are deeper than usual and your risk of getting 
  stuck or swept away is especially high and the road may have been 
  washed away underneath.  These unusually deep floodwaters have 
  already washed away culverts and damaged road surfaces.  
  Barricades will remain in place even after floodwaters have 
  receded to allow crews to assess road stability so please find an 
  alternative route to get to your destination safely.

* Beaverdam Creek will gradually recede overnight tonight, falling 
  below Moderate Flood Stage by 2:00am, below Minor Flood Stage by 
  Friday morning, and below Action/Advisory/Bankfull Stage by Friday 
  evening, as long as additional heavy rainfall does not occur.  
  However, additional heavy rainfall and resultant new rises are 
  possible through Friday afternoon, so do not let your guard down.

* Some locations that may continue to experience flooding include...
  Elberton, Bowman, Dewy Rose and Vanna.

* Additional heavy rainfall is possible tonight through Friday 
  morning and may cause new flooding to develop.  Please stay 
  weather aware and have multiple ways to receive warnings if 
  additional flooding occurs.  A Flash Flood Watch remains in effect 
  until 1200 PM EDT Friday for portions of northeast Georgia, 
  western North Carolina, and upstate South Carolina.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

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

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