Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
942 AM EDT Fri Apr 19 2019

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Oconee County in Upstate South Carolina...

* Until 330 PM EDT.

* At 931 AM EDT, Doppler radar and automated gauges indicate 
  repeated rounds of heavy rainfall are moving through Oconee County 
  with rainfall rates of 1-3 inches per hour.  At least two distinct 
  additional rounds of rainfall are moving into Oconee County 
  especially from Wahalla and Salem south towards Westminster, 
  Seneca, and Lake Keowee.  These additional rounds of rainfall will 
  produce another 1-3 inches of rainfall on top of the 1-2 inches 
  that has already occurred. This will exacerbate any ongoing 
  flooding and will likely cause more significant flooding to 
  develop across Oconee County over the next 1-2 hours.

* People in Oconee County, especially from Salem and Wahalla south 
  towards Westminster, Seneca, Lake Keowee and the Pickens and 
  Anderson County lines, are urged to stay a 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!

* Some locations that may experience flooding include...
  Seneca, Walhalla, Westminster, Salem, Lake Keowee, Devils Fork
  State Park, Oconee State Park, Mountain Rest, Long Creek and Bad
  Creek.

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.

Excessive runoff from heavy rainfall will cause flooding of small
creeks and streams, highways, and underpasses. Addditionally, country
roads and farmlands along the banks of creeks, streams, and other
low-lying areas are subject to flooding.

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
328 PM EDT Fri Apr 19 2019

The National Weather Service in Greenville-Spartanburg has extended
the

* Flash Flood Warning for...
  Oconee County in Upstate South Carolina...

* Until 930 PM EDT Friday.

* At 321 PM EDT, Doppler Radar indicated heavy rainfall has ended 
  across Oconee County.  Doppler Radar and automated rain gauges 
  indicate widespread storm-total rainfall of 3-6 inches with 
  isolated rainfall of 6-7 inches especially in a line near 
  Westminster to Walhalla to near Salem.  This has caused 
  significant flash flooding across Oconee County.  Additional 
  rainfall is possible as new rounds of showers and storms develop 
  over central and eastern Georgia, but at this time it is believed 
  the heaviest rainfall has already occurred and any additional 
  rainfall should not cause new flooding to develop.

* Oconee County 911 is reporting numerous roads have been flooded 
  and numerous streams have exceeded their banks and flooded 
  adjacent low-lying areas.  The Little River is causing significant 
  flooding of farmland near Salem.  A few parked cars were also 
  flooded.  Additional impacts are likely.

* EVEN THOUGH HEAVY 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! 
  Therefore, even though the heavy rain has ended, 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.  Please obey all barricades and 
  evacuation orders!

* Some locations that may continue to experience flooding include...
  Seneca, Walhalla, Westminster, Salem, Lake Keowee, Devils Fork
  State Park, Oconee State Park, Mountain Rest, Long Creek and Bad
  Creek.

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.

Numerous roads and bridges are still threatened by 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

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, 6:54 AM EDT, 2 hours 48 minutes earlier.

Area forecast discussion, Apr 19, 6:54 AM EDT, 2 hours 48 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
654 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 650 AM...Latest radar imagery showed a well defined line
thunderstorms extending north out of the Gulf fo Mexico into the
Southern Appalachians. Some thunderstorms have been strong to severe
with a couple of warnings already issued this morning (no damage
reports so far). Rainfall rates of 1 to 3 inches per hour raise some
hydro concerns, but the line is moving just fast enough to alleviate
these concerns somewhat. However, there is the potential that this
line will slow down or training of storms could become more
prevalent, increasing this risk. Have tweaked PoPs and other avn
grids to match the latest trends.

Otherwise, the big story continues to be the dynamic upper low
pressing east into the Deep South and the associated severe weather
potential for our area later today. The latest radar showed an
organized line of convection (QLCS) stretching north to south from
the Gulf of Mexico into eastern TN. The upper low responsible for
this line of convection is expected to close off across northern MS
this afternoon before curling east and then northeast into the
southern to mid Appalachian mtns tonight. The closed low will slow
down somewhat while beginning 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 (especially for the I-77 corridor) 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 after 11
am 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. In fact
SPC has issued an moderate risk of severe weather for the I-77
corridor including Charlotte meaning that scattered severe
thunderstorms are likely. The severe risk gradually decreases
heading west across the FA. 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. Leaning towards
more 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 super cells behind the system (mini due to the relative lack of
instability. The slow moving nature of convection with the main line
of convection in particular will likely cause at least some 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 /12Z 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.
