Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
716 PM EDT FRI MAY 18 2018
The National Weather Service in Greenville-Spartanburg has issued a
* Flash Flood Warning for...
Northwestern Rutherford County in western North Carolina...
Polk County in western North Carolina...
* Until 1015 PM EDT.
* At 713 PM EDT, Doppler radar indicated a series of heavy rain
producing showers and thunderstorms moving repeatedly northward
across Polk County and into western Rutherford County. These
showers were producing rainfall at rates of 1 to 2 inches per
hour, and this heavy rainfall will continue through at least 9 PM
EDT. Flash flooding will likely develop quickly in this area.
* Some locations that will experience flooding include...
Columbus, Tryon, Saluda, Chimney Rock State Park, Mill Spring,
Lake Adger, Green Creek and Bat Cave. Flash flooding will be most
likely along Britten Creek, Panther Creek, and Ostin Creek west of
Mill Spring.
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. Be especially
cautious at night when it is harder to recognize the dangers of
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.

...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 1015 PM EDT FOR
NORTHWESTERN RUTHERFORD AND POLK COUNTIES...
At 844 PM EDT, a very serious flash flooding and landslide situation
has developed across western Polk County late this evening. Radar
and rain gages indicate that some 2 to 4 inches of rain have fallen
across the western half of the county in the past three hours, and
this has impacted areas that have already received heavy rainfall
earlier in the day and earlier this week. Polk County is reporting
numerous mudslides occurring from near Saluda to near Tryon along
and near the Saluda Grade, and serious flooding will likely develop
in these areas and southward toward the Greenville County border
through 10 PM.
Anyone living in this area who resides along steep slopes should
watch out for mudslides late this evening. Be prepared to evacuate
quickly. Flash flooding will develop quickly and may become quite
serious. Prepare to flee quickly to higher ground.
Some locations that will experience flooding include...
Columbus, Tryon, Saluda, Chimney Rock State Park, Mill Spring, Lake
Adger, Green Creek and Bat Cave.
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. Be especially
cautious at night when it is harder to recognize the dangers of
flooding.
The additional heavy rain will increase 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.
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

HGWhat 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 May 18, 5:48 PM EDT, 1 hour 28 minutes earlier.
Area forecast discussion, May 18, 5:48 PM EDT, 1 hour 28 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
548 PM EDT Fri May 18 2018
.SYNOPSIS...
The threat for numerous showers and a few thunderstorms will linger
into Saturday as a slow moving low pressure system impacts our
region. Locally heavy rainfall will remain possible until the low
departs. High temperatures will be near to just above normal and low
temperatures about ten degrees above normal.
&&
.NEAR TERM /THROUGH SATURDAY/...
As of 550 PM EDT Friday: Minor adjustments made to temperatures
to coincide with latest trends as the rest of the near term
forecast remains on track.
A Flash Flood Watch remains in effect for portions of the FA
through tonight. Showers and isolated thunderstorms continue to
move northward up across the NC mountains and northern foothills
attm, with torrential rainfall and already saturated grounds
favoring the continuation of flooding issues. Elsewhere, latest
radar depicts a new batch of convection moving into the
southern portions of the FA (northeastern GA and the Upstate),
remaining well west of the I-77 corridor. Expect this shower and
thunderstorm activity to continue well throughout the evening
hours as suggested by latest guidance.
Otherwise, a broad upper level trof continues to spin across the
South maintaining deep and moist s/ly flow into the FA. This pattern
will change little during the period, with some n/ly lift expected
by Sat afternoon. Expect less thunder chances overnight, yet still a
high PoP -shra thru the morning with a continued hydro threat across
the srn BR. Thunderstorms will once again be possible by mid-day Sat
within a persistent and high confidence synoptic pattern. Mins
overnight will be held abt 10 degrees F abv normal with widespread
low cloud cover. Maxes Sat will be right arnd normal and with high
sfc td/s it will feel rather muggy once again.
&&
.SHORT TERM /SATURDAY NIGHT THROUGH MONDAY/...
As of 225 PM EDT Friday: Subtropical anticyclone remains anchored
off the Southeast Atlantic coast throughout the period. Another
upper low, although weaker and not well defined, will move out of
the Gulf of Mexico into the Gulf coast states by Monday. These
features keep a moist south to southwest low level flow across the
area each day. The good news is the deep tropical moisture fetch
will not return during this period. However, instability will
increase each day, along with decent upper divergence, keeping the
threat of mainly diurnal convection in place. Greatest coverage
continues to be across the mountains both days with high end
scattered coverage elsewhere. Shear is relatively weak both days,
but surface delta theta-e values increase with steadily drying mid
levels. This leads to an increasing threat of severe thunderstorms
each day, but these should remain isolated as overall DCAPE values
remain on the low side. Heavy rain is possible but the threat is not
as widespread as in previous days. Still, the wet antecedent
conditions could make flooding possible with lower rainfall amounts.
Highs will be nearly steady around 5 degrees above normal. Lows will
be nearly steady as well but around 10 degrees above normal.
&&
.LONG TERM /MONDAY NIGHT THROUGH FRIDAY/...
As of 200 PM EDT Friday: Still little airmass change expected as the
medium range begins Monday night. Models are generally plagued by
disagreement in the finer details of the forecast, which
unfortunately make all the difference in a nebulous pattern like the
present one. A Bermuda high will remain off the east coast in the
Atlantic (welcome to summertime), with the southeast on the northern
periphery of an upper subtropical high. Some type of surface
stationary boundary will likely be laid over the Carolinas through
much of the next work week with little progression out of the area
expected. The GFS does spin up an upper/surface low over the
northern Gulf and swing it up towards our area Wednesday, but that
is likely an artifact of a known convective feedback problem in the
GFS (the parallel FV3 core has it too while the low is absent on all
other global models, suggesting this is a GFS model physics issue).
I've therefore favored the ECMWF through much of the medium range.
As far as sensible weather, the Bermuda high will induce weak
southerly flow over the area, though it is not as persistent our
stout as it has been over the past week. PWATs will remain elevated,
but in the absence of much large-scale forcing, a mostly diurnal
pattern favoring afternoon showers and thunderstorms will persist
through next week. Shower and thunderstorm coverage should be
decreased from this week, and chances of any flooding or severe
storms do not stand out any particular day next week at the moment.
The pattern we will enter into next week looks distinctly summer-
ish, as a matter of fact, just with a bit more moisture than usual
to work with. Max temperatures will increase a little to just above
average, with lows remaining about 10 degrees above average.
&&
.AVIATION /22Z FRIDAY THROUGH WEDNESDAY/...
At KCLT and elsewhere: A highly moist airmass will continue to lift
across the area thru the period. This will create widespread -shra
and perhaps a few short-lived general tstms at times. CIGs will
remain VFR to MVFR this afternoon all sites...then drop overnight
into more widespread MVFR with IFR likely over most terminals arnd
daybreak. Thunder activity shud wane overnight with increasing
chances by late morning.
Outlook: Unsettled weather will continue into the weekend with
isolated to scattered SHRA/TSRA throughout the day/night periods and
deteriorating restrictions at times.
