  into Tennessee. The showers and thunderstorms will remain across 
  the area Tuesday night as the remnants move into eastern Kentucky. 
  The heaviest rainfall will be Tuesday afternoon into Tuesday

The Flash Flood Watch continues for

* Portions of northeast Georgia, western North Carolina and upstate 
  South Carolina, including the following areas, in northeast 
  Georgia, Habersham, Rabun and Stephens. In western North Carolina, 
  Avery, Buncombe, Burke Mountains, Caldwell Mountains, Eastern 
  McDowell, Eastern Polk, Graham, Greater Burke, Greater Caldwell,

  Mountains, Southern Jackson, Swain, Transylvania and Yancey. In 
  upstate South Carolina, Greater Oconee, Greater Pickens, 
  Greenville Mountains, Oconee Mountains and Pickens Mountains.

* From 8 AM EDT this morning through Wednesday afternoon.

* Showers and thunderstorms will gradually increase in coverage 
  throughout the day as Tropical Depression Ida moves across the 
  Tennessee Valley. Widespread showers and a few thunderstorms will 
  remain across the area through tonight before tapering off during 
  the day Wednesday. The heaviest rainfall is expected this 
  afternoon through this evening in the Watch area. Storm total 
  rainfall of 3 to 6 inches is expected near the southern facing 
  upslope favored areas along the North and South Carolina border 
  west to the Georgia-North Carolina border. Totals of 1 to 3 inches 
  are possible across the rest of the Watch area. Locally higher 
  amounts are possible.

* The expected heavy rainfall will result in some streams and creeks 
  overflowing their banks, likely flooding some roadways. Minor main 
  stem river flooding is also possible. Deep ponding of water in 
  low-lying and poor drainage areas may also flood some roadways. 
  Steeply sloped terrain may be more susceptible to landslides than 
  is normal due to the heavy rain that fell across the area two 
  weeks ago.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Rainfall of more than five inches in similar storms has been 
associated with an increased risk of landslides and rockslides. If 
you live on a mountainside or in a cove at the base of a mountain, 
especially near a stream, be ready to leave in advance of the storm 
or as quickly as possible should rising water, moving earth, or

What forecasters said that day

The local office's own words before this flash flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Greenville-Spartanburg, SC wrote its last area forecast discussion before this flash flood watch went out at Aug 30, 1:27 PM EDT, 1 hour 42 minutes earlier.

Area forecast discussion, Aug 30, 1:27 PM EDT, 1 hour 42 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
127 PM EDT Mon Aug 30 2021

.SYNOPSIS...
Tropical cyclone Ida will continue to weaken while moving
northeast from Mississippi toward West Virginia on Tuesday and
Wednesday, bringing periods of heavy rain and gusty wind.
Continental high pressure is expected to settle into the region
later in the week with mostly sunny skies and near to slightly below
normal temperatures.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1040 AM Monday: 12Z RAOBs show capped atmos remains in place
despite the expected weakening of the upper ridge as mentioned
below. Even the CAMs have backed off on convective coverage over the
mountains this afternoon and evening as forecast soundings show the
cap lingering even over the mountains. Have backed off as well but
not removed entirely as they are the most likely location to see any
diurnal convection.

Upper anticyclone centered just southeast of the CWA this morning
will gradually drift southeast and weaken through the period, as
height falls associated with Hurricane Ida gather some speed in
lifting from the lower Miss Valley toward the TN Valley through the
period. Temps will again be around 5 degrees above normal.

Spotty high terrain convection could linger through the evening,
while weakening outer bands associated with the approach of T.C. Ida
could make a run for far western areas by sunrise Tuesday. 20-40
PoPs will therefore be featured for much of the tonight period
across the mountains.

&&

.SHORT TERM /TUESDAY THROUGH WEDNESDAY/...
As of 345 AM EDT Monday: Tropical cyclone Ida is still expected to
become post-tropical while accelerating through the Tennessee Valley
into the Central Appalachians Tuesday afternoon into Wednesday.
Guidance has continued to slowly trend closer to the forecast area.
This combined with increased high resolution guidance supports an
uptick in expected rainfall intensity and amounts with generally one
to locally three inches of rain expected, except three to five
inches and locally higher for south facing escarpment and southwest
mountains. The Weather Prediction Center has upgraded the slight
risk of excessive rainfall to a moderate for areas with higher
rainfall amounts. We may eventually need a Flash Flood Watch for
some of these areas. Deep tropical moisture and forcing as well as a
period of about six hours of favorable orographic enhancement will
support periods of heavy rain is expected to begin as early as
Tuesday afternoon across the Southwest mountains and become more
widespread into Tuesday night before gradually tapering off from
southwest to northeast Wednesday.

The closer proximity of Ida also ups the ante for gusty southerly
winds late Tuesday into early Wednesday focused across the ridgetops
and also possibly the French Broad River Valley given its roughly
south to north orientation. Wind gusts of 30 to 40 mph will be
possible along the ridge tops thanks to a 40 kt jet at 850 mb with
gusts of 20 to 30 mph in play for the French Broad Valley and in
heavier showers or thunderstorms outside of the mountains. This
combined with heavy rainfall may support some downed trees or power
lines where higher gusts occur.

Lastly, there is a low end risk of isolated weak and brief tornadoes
given the highly sheared enviroment. Model soundings still indicate
mid-level capping and resultant low end instability, which is the
main factor limiting this threat. It's a bit too earlier too
highlight any given area within the forecast area as the timing is
still a bit too far out late Tuesday into the overnight.

The widespread rain and clouds will temper the tropical airmass with
daytime highs cooling to near 80 for most Wednesday and overnight
lows near 70.

&&

.LONG TERM /WEDNESDAY NIGHT THROUGH SUNDAY/...
As of 145 AM EDT Monday: The extended period Thursday into this
weekend will provide well deserved quiet weather. The remnants of
Ida will continue to be absorbed into the mid-latitude westerlies,
effectively energizing a long wave trough as it pushes off of New
England Thursday into Friday. A continental air mass building in on
the heals off the departing trough will provide much drier
conditions with any lingering showers mainly confined to the
northern mountains coming to an end by Thursday evening. Surface
high pressure will settle into the area by the weekend with light
winds and clear skies providing good radiational cooling conditions
at night and the first taste of fall just in time for meteorological
fall (which starts September 1st) with lows in the 50s mountain
valleys to around 60 east of the mountains. Nearly full sun and
increasing heights thanks to an elongated ridge building in from the
west will still support highs mainly in the 80s, except possibly
returning to low 90s east of the mountains by Sunday. Even still
only slowly rebounding dewpoints will take an edge off the building
heat compared to what we've experienced as of late.

&&

.AVIATION /18Z MONDAY THROUGH SATURDAY/...
At KCLT and elsewhere: Upper level high pressure and the suppressed,
relatively dry air mass remains over the area into the evening. In
fact, cumulus was slower to develop than the past several days.
Latest CAMs have backed off on convective chances over the
mountains. There is convection off to our NW and this may move in
before sunset, but chance to low for even the KAVL TAF. Cumulus
dissipates this evening but mid and high clouds will spread over
the area. Think this will limit mountain valley fog and have kept
KAVL at MVFR for now. SW wind this afternoon becomes light
overnight. Low VFR does move in during the day Tuesday as the
remnants of Tropical Cyclone Ida move into TN. Precip chances
increase through the day, but timing has limited PROB30 mention to
the most likely locations. Gusty S to SW winds will also develop
during the day.

Outlook: Periods of rain/restrictions and some gusty winds can be
expected Wednesday as the remnants of Ida move by to our north.
Drying follows for the latter part of the week.
