BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
705 PM EDT Wed Mar 23 2022

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Southeastern Jackson County in western North Carolina...
  Southeastern Macon County in western North Carolina...
  Transylvania County in western North Carolina...

* Until 1015 PM EDT.

* At 705 PM EDT, Doppler radar and automated rain gauges indicated 
  thunderstorms producing heavy rain across the warned area. Flash 
  flooding is ongoing or expected to begin shortly.  This warning 
  encompasses much of the Upper French Broad basin from Brevard to 
  Rosman, and then extending west along the Highway 64 corridor to 
  around Cashiers and Highlands.  Heavy rain has been falling 
  periodically since early this morning and additional heavy storms 
  developing will aggravate already saturated ground.

  HAZARD...Flash flooding caused by thunderstorms.

  SOURCE...Radar and automated gauges.

  IMPACT...Flash flooding of small creeks and streams, urban
           areas, highways, streets and underpasses as well as
           other poor drainage and low-lying areas.

* Some locations that will experience flash flooding include...
  Brevard, Highlands, Rosman, Cashiers, Lake Toxaway, Gorges State 
  Park, Lake Jocassee, Looking Glass, B.R. Parkway-Black Balsam To 
  Mount Pisgah, Dupont State Forest, Balsam Grove, Wolf Mountain, 
  Sapphire, Connestee, Bad Creek, Cedar Mountain, Penrose, Whiteside 
  Mountain, Little River In Transylvania County and North 
  Transylvania.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Heavy rain is increasing the risk of landslides, especially in areas 
where slides have occurred in the past. Be especially alert if you 
are near a stream, especially at the base of a mountain or in a 
cove. Watch for loose-moving soil and rocks or a sudden increase in 
streamflow. Leave the area quickly if this is observed. When driving 
along roads where the terrain is steep or rocky, watch and listen 
for falling rocks, mud, trees and other debris.

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

At 927 PM EDT, Lingering heavy showers will continue to aggravate 
saturated soil conditions countywide through late evening, and also 
maintain high water conditions and elevated stream, creek and river 
levels. Flooding of low-lying areas is likely to remain as well.

HAZARD...Flash flooding caused by thunderstorms.

SOURCE...Radar and automated gauges.

What forecasters said that day

The local office's own words before this flash flood warning 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 warning went out at Mar 23, 6:07 PM EDT, 58 minutes earlier.

Area forecast discussion, Mar 23, 6:07 PM EDT, 58 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
607 PM EDT Wed Mar 23 2022

.SYNOPSIS...
A cold front will move to the Carolina coast on Thursday.
Cooler air will begin spilling into the region on Friday, with
additional disturbances arriving over the weekend from the northwest
to reinforce the cooler air across the area. Light snow showers will
be possible across the higher ridges of the North Carolina mountains
over the weekend. Expect warmer weather in the first half of next
week ahead of the next cold front.

&&

.NEAR TERM /THROUGH THURSDAY/...
As of 6pm EDT Showers have been a bit widely scattered early this
evening with with some more general convective showers over western
NC.  Development of stronger and possibly severe storms is possible
generally near and southeast of the I85 corridor.  Risk for severe
development will end from west to east as frontal system progresses
southeastward, and after dark as the boundary layer becomes more
stable. Deep layer shear is quite strong, and combined with some
CAPE will continue a risk for severe weather.

Overnight, as postfrontal air impinges on the region, profiles will
rapidly dry out.  All the CAMs (with the exception of the bullish
and likely overdone NAMnest) depict an end to rain by 01-03Z and
steady clearing after midnight.  Temperatures nonetheless look to
stay 7-9 degrees above normal tonight.

&&

.SHORT TERM /THURSDAY NIGHT THROUGH SATURDAY/...
As of 1215 PM EDT Wednesday: The expected trough passage may be a
bit slower than previously anticipated, leading to a prolonged
period of west to northwest flow atop the region Friday into the
weekend. The upslope flow near the TN border will likely support at
least isolated showers at times, especially north of I-40. Lowering
heights/thicknesses will support well below normal temperatures
especially across the mountains and may support a mixture with or
changeover to snow at times at higher elevations. Still challenging
to pin down the potential for accumulations at the highest
elevations as guidance is struggling with the placement of a potent
short-wave trough Saturday or Saturday night. Decent upper support
and tightening surface pressure gradient will support gusty winds
(possibly reaching advisory level across the mountains). If fuels
dry out fast enough, the gusty winds and drying east of the
mountains may support elevated fire danger. Despite continued wind
into the overnight, Saturday night will be notably cold for this
time of year with lows in the 30s except 20s above 3000 feet and in
sheltered valleys.

&&

.LONG TERM /SATURDAY NIGHT THROUGH WEDNESDAY/...
As of 12 PM EDT Wednesday: Near normal forecast confidence takes a
nose dive by mid week as guidance cannot decide how much phasing
occurs with northern and southern stream jets over the central U.S.
Short-wave ridging will support temperatures rebounding to at least
to near normal early in the week. Although one more day of frosty
morning lows is possible Monday, especially for northern areas.
Prolonged dry conditions could lead to elevated fire conditions
should low afternoon relative humidity values prevail. A warm front
lifting north in response to building heights may brush the area
with a myriad of mainly mid to high clouds Monday into Monday night.
Cannot rule out a few sprinkles or showers focused across the
northern mountains during this time. Otherwise, expect mostly sunny
skies to prevail.

Unsettled weather will likely return sometime mid-week (Wednesday or
Thursday), but it may be short lived as the weather pattern becomes
zonal and more progressive. Temperatures will likely peak above
normal before the potential cold front passage midweek.

&&

.AVIATION /22Z WEDNESDAY THROUGH MONDAY/...
At KCLT and elsewhere: Widespread showers and a few rumbles of
thunder continue across the Upstate and NC Piedmont, with the entire
region locked into a swath of MVFR ceilings and more localized areas
of IFR/LIFR restrictions.  Widespread showers should continue for
the next few hours, as unstable profiles promote convection ahead
of an approaching cold front.  Some additional deterioration is
expected this evening, with additional showers at all TAF sites
likely to result in lowered ceilings and reduced visibilities.
For now, advertising mostly prevailing MVFR with periods of IFR.
Have removed mention of thunder from KCLT in favor of +SHRA, as
widespread rainfall and thick stratus early this afternoon may limit
convective potential later this evening.  The Upstate sites retain a
VCTS mention through late evening, at which point conditions slowly
improve through the end of the TAF period.  A return to mostly-VFR
ceilings is anticipated by daybreak Thursday, with perhaps a few
remnant areas of MVFR visibility, especially in the mountains.
Otherwise, winds should gently transition from SSE to SW through
the period, with a shift toward more W/WSW anticipated late in
the day Thursday.

Outlook: Clearing should continue into Friday.  Low-level moisture
and NW flow will bring an increase in clouds and potentially some
light precipitation into the forecast Friday evening into Saturday.
