BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
1139 AM EDT Fri Apr 19 2019

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Northwestern Greenville County in Upstate South Carolina...
  Pickens County in Upstate South Carolina...

* Until 530 PM EDT Friday.

* At 1127 AM EDT, Doppler Radar and automated rain gauges indicate 
  that areas of northern and western Pickens County and extreme 
  northwestern Greenville County have received 2-4 inches of 
  rainfall in the past 4-6 hours, which isolated totals of 4-5 
  inches in some locations.  This is causing significant runoff on 
  area streams and significant Flash Flooding may be imminent, 
  especially across northwestern Pickens and northwestern Greenville 
  Counties from Six Mile, to Pickens, to Pumpkintown northwest to 
  Table Rock Reservoir, Rocky Bottom, Sunset, and Nine Times.

* People in are urged to stay away from low-water crossings, low-
  lying roadways adjacent to streams, and all areas adjacent to 
  streams including parks, greenways, farmland, and residences 
  including apartment buildings and campgrounds. Water will rise 
  quickly and you will have little time to respond or evacuate. Seek 
  higher ground immediately!

* The flood threat will persist for several hours, so it is 
  important not to let your guard down as streams will continue to 
  rise and new flooding may develop well into the afternoon hours. 
  Please avoid low-lying areas through this afternoon and obey all 
  barricades and evacuation orders as they are in place to save your 
  life!

* The following streams and associated tributaries are experiencing 
  rapid rises and flooding is likely: Twelvemile Creek near Pickens, 
  Katoma Branch near Nine Times, Little Eastatoe Cree near Sunset, 
  Rocky Bottom Creek, Oolenoy River near Pumpkintown and the South 
  Saluda River near Cleveland.

* Some locations that will experience worsening flooding include...
  Easley, Clemson, Pickens, Central, Liberty, Norris, Six Mile,
  Jocassee Gorges, Jones Gap State Park and Lake Jocassee.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Most flood deaths occur in vehicles. Do not attempt to cross
water-covered roadways, bridges, or low-level crossings. Only a few
inches of rapidly flowing water can carry away your vehicle. It is
not worth the risk. Please TURN AROUND, DON'T DROWN.

In hilly and mountainous terrain, there are hundreds of low-water
crossings which can be dangerous in heavy rain. Low-water crossings
can be submerged by flood waters quickly and without warning. Never
attempt to travel across flooded crossings. Find an alternate route.
It takes only a few inches of swiftly flowing water to carry vehicles
away.

Numerous roads, parking lots and bridges will be threatened by heavy
rain and rapidly rising streams and creeks. Please pay close
attention to road signs indicating a flood-prone area. Obey all
barricades, even if water is not currently over the road. Barricades
are in place for your protection and indicate areas where flooding
can occur rapidly and without warning.

When it is safe to do so, please report flood waters or landslides
flowing over roads or threatening property to the National Weather
Service by calling toll free, 1, 800, 2 6 7, 8 1 0 1, by posting on
our Facebook page, or via Twitter using hashtag NWSGSP. Your message
should describe the event and the specific location where it
occurred, including roadways, nearby cross streets, stream names and
other landmarks.

Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
507 PM EDT Fri Apr 19 2019

The National Weather Service in Greenville-Spartanburg has extended
the

* Flash Flood Warning for...
  Northwestern Greenville County in Upstate South Carolina...
  Pickens County in Upstate South Carolina...

* Until 1130 PM EDT Friday.

* At 505 PM EDT, Doppler radar indicates that the heaviest rainfall 
  has moved through Pickens County.  Storm-total rainfall of 5-7 
  inches been observed by automated gauges and Doppler radar, 
  primarily across northwestern Pickens County from Six Mile to Nine 
  Times to Sunset to Rocky Bottom.  South and east of this axis, 
  towards Pickens and Liberty, rainfall amounts are lower, generally 
  1-3 inches.  

* An additional band of showers and thunderstorms is approaching 
  Pickens County and will result in a brief burst of heavy rainfall. 
  However, this line is not expected to exacerbate ongoing flooding. 
  Due to continued excessive runoff and high stream levels causing 
  lowland flooding, the Flash Flood Warning will be extended until 
  the final round of rainfall has left the county and water levels 
  have receded.

* Pickens County Emergency Management has indicated a few roads have 
  flooded and have been closed as a result of flash flooding 
  including Meese Mill Rd and Clyde Chapman Dr along Cove Creek and 
  Sliding Rock Rd.

* Even though the heaviest rain has ended, significant runoff 
  continues as the rainfall works through the soils and into 
  streams. Streams will continue to rise and will stay elevated for 
  several hours!  People are urged to stay away from low-water 
  crossings, low-lying roadways adjacent to streams, and all areas 
  adjacent to streams including parks, greenways, farmland, and 
  residences including apartment buildings and campgrounds. Please 
  obey all barricades!

* Some locations that may experience additional flooding include...
  Easley, Clemson, Pickens, Central, Liberty, Norris, Six Mile,
  Jocassee Gorges, Jones Gap State Park and Lake Jocassee.

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 Apr 19, 10:51 AM EDT, 48 minutes earlier.

Area forecast discussion, Apr 19, 10:51 AM EDT, 48 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
1051 AM EDT Fri Apr 19 2019

.SYNOPSIS...
A strong cold front will move through the forecast area today
bringing showers and thunderstorms to the region. There is a
good chance that some of these storms could become severe as
the front moves through the area. Cooler temperatures and
lingering showers are expected behind the front. Temperatures
will warm again by early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 1030 AM: Band of precip with embedded linear convective
segments continues to progress eastward into the CWFA. Previous
thinking w.r.t. severe potential remains essentially the same,
and all of the ingredients for high-shear/low-CAPE impacts still
are present or progged to come together by early afternoon. A
number of minor wind damage reports have already been received
from areas affected by the better organized segments, with minor
flood impacts also having developed in the areas near the southern
facing Blue Ridge Escarpment. A Tornado Watch just was issued to
cover the area that has not already seen the stabilizing impacts
of the rain, and is valid until 5 PM EDT. Have updated timing of
PoPs and thunder mention across the CWFA, and temp/dewpt trends
were closely tied to the HRRR output, which is our best choice in
such a rapidly changing environment.

Overall, a closed upper low in the Mid-South will slow down somewhat
while the surrounding trough begins to acquire a negative tilt. This
will likely do two things. One, it will provide a significant
couplet of strong synoptic ascending and descending air associated
with a 120 kt jet streak overhead. Two, the slowing should allow
for diurnal instability over the eastern half of the area, that is,
the area where activity has not yet really fired, to be able to tap
into strong shear (0-1 km BS of 40+ kts) just above the surface
(two key ingredients for severe weather). The leading line of
convection (QLCS) looks to have the greatest widespread severe
threat prior to 4 pm, with severe winds (in excess of 58 mph)
the primary threat due to the potential for a strong rear inflow
jet associated with the QLCS with a secondary threat for both
tornadoes and severe hail. SPC Moderate Risk remains in effect
for the I-77 corridor including Charlotte meaning that scattered
severe thunderstorms are likely. The severe risk gradually decreases
heading west across the FA, but the latest Day 1 outlook is more
or less identical to the previous issuance within the CWFA. The
mode of convection is more up for debate after the initial line as
model guidance does show a secondary frontal feature following the
main one, but the question remains as to how much instability will
be left and how any convection may organize along or out ahead of
it. There remains enough model support to expect some disorganized
convection moving generally SW to NE as llvl flow veers to the SW
with the upper low nearing the FA later this afternoon. Can't rule
out a few supercell thunderstorms developing ahead or along the
main line of convection (if there are breaks) or mini supercells
behind the system, with instability being limiting factor at
that time.  The slow moving nature of convection with the main
line of convection in particular will cause at least isolated
hydro issues to small streams and roadways (WPC slight risk for
excessive rainfall across the region). The strong southerly winds
along and ahead of this system will support gusty winds across
the high elevations, especially SW mountains where a wind advisory
has been posted and continues through noon.

Most areas will see rain and thunderstorms come to an end by this
evening as the main forcing exits NE of the region. However, the
cold core upper low will support snow levels falling to around 4K
feet and potential for accumulating snows at this level with several
inches possible above 5K feet, especially where the best upslope
flow (from the SW) overlaps with good synoptic lift and moisture
across the SW mtns. As of now the main winter weather impacts
appear to be above 5K feet so any winter products will be shelved
for now, but considered on future shifts. Temps for most areas
will only fall into the 40s and 50s (30s higher mtn elevations)
due to continued breezy conditions, so frost should not be an issue.

&&

.SHORT TERM /SATURDAY THROUGH SUNDAY NIGHT/...
As of 235 AM EDT Friday: the short-term fcst picks up at 12z on
Saturday with an impressive upper low centered just to our north
as steep upper ridging spreads over the Western CONUS. Because
this system is essentially cut-off from the northern-stream upper
flow, it will push eastward very slowly and is not expected to
move off the Atlantic Coast until the very end of the period on
Monday. At the sfc, a substantial low pressure system will be
centered to our NNW and over the Ohio River Valley as the cold
front associated with it moves offshore. Over the next 24hrs or
so, the low will remain nearly stationary as a substantial plum
of deep-lyr moisture spreads over much of the CWFA from the west.
The latest model guidance continues to open up the low by Sunday
morning as the system gradually lifts NE of the fcst area and
drier air moves back over the area. For the rest of the period,
drier high pressure centered over the Northern Gulf of Mexico
will persist over the Southeast. As for the sensible fcst, we
will likely have some lingering precip on Sat with the remainder
of the period being dry. With the impressive cold-air advection
expected across the region and unusually low thickness values,
some snow flurries are expected over the higher elevations early
Sat and early Sun. Some accumulating snow is possible above 3500
ft, with a better chance above 5000ft. At this time, I do not
anticipate any winter hazard products will be needed, but if
expected snow amounts trend upwards then hazards cannot be ruled
out. The resulting windy conditions should help inhibit any frost
formation across the active zones (which is everywhere except the
Northern NC Mountains). Temps should warm back into the upper 60s
to low 70s across the lower elevations on Sunday, with more warming
as we move into the extended period.

&&

.LONG TERM /MONDAY THROUGH THURSDAY/...
As of 245 PM EDT Thursday: Upper low over the Mid-Atlantic will
continue to lift north, with high pressure building in and
increasing thicknesses. Temperatures will increase through the
extended, 5 to maybe even 10 degrees above seasonal. A shortwave
spinning around the upper low may bring some showery activity or
even possible thunderstorms Tuesday afternoon, GFS a little stronger
with this idea than ECMWF. Next system gearing up over the Rockies
will push off into the Plains sometime midweek, but there are some
very significant timing differences between the global models, so
frankly opted to keep a fairly generic blend through the end of the
period and into the new day 7. As a note to readers, depending on
how near-term activity shapes up tonight, the extended forecast may
not be updated until Friday afternoon.

&&

.AVIATION /15Z FRIDAY THROUGH TUESDAY/...
At KCLT and elsewhere: Rapidly deteriorating conds expected between
12Z and 18Z associated with a dynamic storm system to move through
the region. Model guidance shows that the strong line of showers and
thunderstorms (QLCS) approaching across the deep south will hold
together and even intensify east of I-26 and especially near the I-
77 corridor, including KCLT. Brief SW/W gusts in excess of 40 kts
is possible with the QLCS. Light to occasionally moderate LLWS is
possible, especially between 15Z and 20Z. LLWS issues may linger at
KAVL behind this time as winds veer to the SW. A secondary impulse
of showers and embedded thunderstorms associated with the leading
edge of the upper low are possible just about anywhere between 18Z
and 00Z.

Outlook: Improving conditions are expected early Saturday. Spotty
restrictions cannot be ruled out over the mtns as an upper low
passes by on Saturday.
