...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 630 AM EDT THIS 
MORNING FOR HABERSHAM COUNTY...

At 119 AM EDT, Doppler radar and automated rain gauges indicated 
another area of heavy rainfall is approaching from the south and is 
beginning to impact Habersham County. Another 1-2 inches of rain is 
possible on top of the 2 and 5 inches of rain that has fallen over 
the past 3-4 hours.  Storm-total rainfall since Saturday morning is 
exceeding 5-6 inches in central and southern Habersham County from 
Clarkesville to Demorest to Cornelia, Baldwin, and Alto.

Due to the additional heavy rainfall, more significant flash 
flooding is imminent especially across southwest Habersham County 
along the Mud Creek watershed west of Cornelia and around the 
Clarkesville vicinity.  Drivers are encouraged to use extreme 
caution and avoid all flooded roadways.  Residents adjacent to small 
streams are encouraged to seek higher ground NOW!

Flash flooding is likely ongoing, especially along small streams and 
poor-drainage areas from Clarkesville to Demorest to Cornelia and 
points west towards the White and Hall county lines.

HAZARD...Life-threatening flash flooding due to thunderstorms.

SOURCE...Doppler radar and automated gauges.

IMPACT...Expect significant, life-threatening flash flooding of
         small streams, potentially significant flooding of urban
         areas, low-lying areas adjacent to streams and drainage
         ditches, low-elevation roadways, farmland and parks.
         Flooding of a few structures and a few roadway and/or
         culvert washouts are possible.

* Some locations that will experience flash flooding include...
  Clarkesville, Cornelia, Baldwin, Demorest, Mount Airy, Alto, Lake 
  Burton, Raoul, Batesville and Hollywood.

* Some streams that are experiencing rapid rises include Mud Creek, 
  Little Mud Creek, Camp Creek, Beaverdam Creek, Hazel Creek, and 
  other tributaries to the Soque River and Mud Creek.  Flash 
  flooding is likely ongoing across several small streams and 
  flooding of larger streams is likely over the next 2-4 hours, 
  including the Soque River from Batesville to Clarkesville to the 
  White County line.

* Flash flooding of low-elevation roadways is likely or ongoing, 
  especially adjacent to small stream and drainage ditches, 
  including Alto-Mud Creek Rd, Duncan Bridge Rd, Old Athens Hwy, and 
  other roadways along and including US 23/GA 365.  Urban flooding 
  of poorly-draining areas around Cornelia, Demorest, and 
  Clarkesville is likely ongoing.

* Additional rainfall amounts of up to 1 inch is possible over the 
  next 60 minutes in the warned area.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

A Flash Flood Warning means that flooding is imminent or occurring. 
If you are in the warned area move to higher ground immediately. 
Residents living along streams and creeks should take immediate 
precautions to protect life and property.

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

Excessive runoff from heavy rainfall will cause flooding of small 
creeks and streams, country roads, farmland, and other low lying 
spots.

...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 630 AM EDT THIS 
MORNING FOR HABERSHAM COUNTY...

At 452 AM EDT, Doppler radar and automated rain gauges indicated 
that the heavy rainfall has ended across Habersham County.  No 
additional significant rainfall is expected through Sunday morning.  
However, the county has seen widespread 4-6 inch accumulations since 
about 10pm last night with storm-total rainfall since Saturday 
morning of as much as 8 inches.  Significant and life-threatening 
flash flooding is ongoing across the county with Habersham County 
911 reporting numerous roads flooded, multiple water rescues, and 
potential structural flooding.  Drivers are urged to obey all 
barricades and avoid all flooded roadways, which are especially 
dangerous in the dark.  Residents near small streams should continue 
to watch stream levels closely and seek higher ground as areas that 
do not normally flood may flood as a result of this morning's heavy 
rain.  Excessive runoff and stream rises will continue for at least 
1-3 more hours even though the rainfall has ended so it is important 
to not let your guard down until streams crest and recede below 
bankfull levels.

HAZARD...Life-threatening flash flooding due to torrential
         thunderstorms.

SOURCE...Doppler radar and automated gauges.

IMPACT...Significant, life-threatening flash flooding of small
         streams, urban areas, low-lying areas adjacent to
         streams and drainage ditches, low-elevation roadways,
         farmland, and parks.  Flooding of a few structures and a
         few road washouts remain possible.

Some locations that will continue to experience flash flooding 
include...Clarkesville, Cornelia, Baldwin, Demorest, Mount Airy, 
Alto, Raoul, Batesville.  Urban flooding around Cornelia, Demorest, 
and Clarkesville is ongoing.


PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles. Obey all barricades, which are in place 
for your protection.

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

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
621 AM EDT Sun Oct 11 2020

The National Weather Service in Greenville-Spartanburg has extended 
the

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

* Until 830 AM EDT.

* At 621 AM EDT, Habersham County 911 continues to report widespread 
  flooding and impacts due to the earlier heavy rainfall across the 
  county.  New flooding reports continue to come in, including 
  impacts to roads and homes, and larger streams including the Soque 
  and the Chattahoochee are still rising.  Daybreak may reveal 
  additional flood impacts not yet reported.  Therefore, the Flash 
  Flood threat has not yet ended and the Flash Flood Warning will be 
  extended through 8am to allow streams to crest and to ensure no 
  new flooding occurs. Drivers are urged to obey all barricades and 
  avoid all flooded roadways.  Residents near small streams need to 
  seek higher ground for the next few hours and allow adjacent 
  streams to crest and recede before returning to low-lying 
  property.  A water rescue is ongoing for residents stranded in 
  their home adjacent to the Soque River so the threat of rising 
  flood waters remains significant.

* Doppler radar and automated rain gauges indicated that the heavy 
  rainfall has ended across Habersham County.  No additional 
  significant rainfall is expected through Sunday morning.  However, 
  the county has seen widespread 4-6 inch accumulations since about 
  10pm last night with storm-total rainfall since Saturday morning 
  of as much as 8 inches.  It is important to not let your guard 
  down until streams crest and recede below bankfull levels.

  HAZARD...Life-threatening flash flooding.

  SOURCE...Law enforcement.

  IMPACT...Significant, life-threatening flash flooding of small
           streams, urban areas, low-lying areas adjacent to
           streams and drainage ditches, low-elevation roadways,
           farmland, and parks.  Flooding of a few structures and
           a few road washouts remain possible.

* Some locations that are continuing to experience flash flooding 
  include...Clarkesville, Cornelia, Baldwin, Demorest, Mount Airy, 
  Alto, Raoul, Batesville.  Urban flooding around Cornelia, 
  Demorest, and Clarkesville is ongoing.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Turn around, don't drown when encountering flooded roads. Most flood 
deaths occur in vehicles.  Obey all barricades, which are in place 
for your safety.

Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1048 PM EDT Sat Oct 10 2020

.SYNOPSIS...
Abundant moisture from the remnants of Delta will continue to stream
over the southern Appalachians and surrounding areas through the
weekend. Drier air will move into the area early next week with a
cold front expected to cross our region early Tuesday. Drier high
pressure will settle in behind the front through Thursday, with
another cold front approaching from the northwest on Friday.

&&

.NEAR TERM /THROUGH SUNDAY/...
As of 1045 PM EDT Saturday: A Flash Flood Watch remains in effect
for portions of the area through Sunday evening.

Minor adjustments made to temps/PoPs/present wx to coincide with
latest trends as the rest of the near term remains on track. While a
brief, isolated tornado could not be entirely ruled out through the
overnight hours, continue to expect the primary threat to be the
rainfall, heavy at times, as moisture from the remnants of Delta
continues to infiltrate in. Flash flooding will be possible. Current
temps range from the low to mid 60s to around 70 degrees.

Previous discussion: Current weak northeasterly CAD regime will
become more southeasterly and increase moisture and precipitation,
especially in upslope areas of the Southern Appalachians.  Storm
Total QPF forecast has not changed a lot, with isolated pockets of 3
to 6 inches possible in the escarpment areas, and 1 to 3 inches
elsewhere.

Circulation from Delta will enhance wind profiles and
give some gusts at higher elevations.  Wind shear profiles will be
generally good enough for severe weather on Sunday, in areas of non-
trivial CAPE.  Chances for convection are somewhat better on Sunday
afternoon as some breaks in cloud cover allow temperatures to warm.
CAPE forecasts, and forecasts of sigtor reach notable levels with
some afternoon heating on Sunday, over basically the eastern half of
the CWA, and is consistent with some strong updrafts seen in high-
res models at that time.  This area is currently under a marginal
SPC risk category, but some part of that area may need to be raised,
and will at least bear watching.

Any severe weather is likely to be on the tail end of the event as
the system that was Delta pulls out to the northeast, with clouds
and rain in decline Sunday evening outside of isolated convective
storms.

&&

.SHORT TERM /SUNDAY NIGHT THROUGH TUESDAY/...
As of 200 pm Saturday: Trough axis associated with the remnants of
T.C. Delta will be lifting across the forecast area at the start of
the period, with lingering potential for locally excessive rainfall.
Additionally,  continued moderate sbCAPE aligned with adequate shear
in the warm sector will support a persistent threat for isolated
severe convection across the Piedmont. Likely to categorical pops
are warranted across much of the forecast area through the evening.

The remainder of the short term will be characterized by rising
heights, supporting unseasonably warm weather, max temps expected to
average around 5 degrees above climo, and mins 10-15 degrees above
normal. Conditions will otherwise become increasingly dry, although
some lingering showers will be possible into Monday morning.
Northern stream height falls Monday night and early Tuesday will
allow a frontal boundary to approach the area from the TN Valley.
With the Gulf of Mexico expected to be more or less closed for
business during this time, small pops (20-30%) with the front will
be primarily confined to the Tennessee border.

&&

.LONG TERM /TUESDAY NIGHT THROUGH SATURDAY/...
As of 225 pm Saturday: Although the front that will cross the area
late in the short term will advect drier air into the region,
conditions will generally remain unseasonably warm through about the
first half of the period. By late in the week, global models agree
that a major trough will take shape across the eastern Conus, with
associated strong frontal zone expected to push into the area on
Friday. The models are not in the best agreement regarding the
magnitude of the moisture/forcing associated with the front, so only
token small pops are carried from late Thu night through Friday.
However, guidance does agree that a major cooling trend will occur
for the Fri/Sat time frame, when temps will likely dip to 10 degrees
below climo...at least. Widespread frost and perhaps some freeze
concerns can therefore be expected across the mountains.

&&

.AVIATION /03Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: A mixture of MVFR/IFR/LIFR prevails at the
TAF sites tonight as the remnants of TC Delta allows for periods of
SHRA/TSRA, low cigs and patchy fog to affect the FA. Expect this
trend to continue through the overnight hours and through Sunday as
the center of circulation passes to the west, with another window of
opportunity for TSRA late Sunday morning/Sunday afternoon. Could not
entirely rule out brief improvement within lull in precip at times.
NE winds will become ENE/ESE on Sunday AOB 10 kts, with SSE at KAVL.

Outlook: Expect gradually improving conditions Monday into Tuesday
as the remnants of TC Delta moves away from the area and drier air
infiltrates into the area.
