Weather Report



Confidence is increasing that an unseasonably warm and moist environment ahead of a strong storm system will set the stage for a rather long-duration (multi-round) period of active weather, including strong to severe storms, capable of producing damaging winds, tornadoes and localized flash flooding.

Primary Storm Threats:

  • Damaging winds > 60 MPH 
  • Tornadoes (best chance south and west of an Ellijay to Gainesville to Athens line)
  • Flash Flooding (and river/stream/creek flooding) due to multiple rounds of heavy rain/storms

Timing: see simulated graphic below

**Round 1 — beginning late this afternoon**

  • 4PM to 9PM — north/west of I-85
  • 7PM to Midnight — south/east of I-85

**Round 2 — beginning after midnight tonight**

  • 1AM to 8-10AM (Wednesday) — north/west of I-85
  • 7AM to 3-6PM — south/east of I-85

** Radar (model) simulation — from ~4PM today through 5AM Wednesday **
