...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 500 AM EDT FOR
CALDWELL AND BURKE COUNTIES...

At 343 AM EDT, Doppler radar and automated rain gauges indicated 
heavy rain over the warned area.  Up to 3 inches of rain have fallen 
since 6:00 PM. Flash flooding is occurring in the warned area.

Excessive rainfall over the warned area will cause mud slides near
steep terrain. The mud slide can consist of rock, mud, vegetation and
other loose materials.

Some locations that will experience flooding include...
Lenoir, Morganton, Valdese, Gamewell, Cajah's Mountain, Drexel, Glen
Alpine, Cedar Rock, Table Rock and South Mountains State Park.

The river stage of Wilson Creek at Edgemont was 6.3 feet. At 5 feet, 
Brown Mountain Rd and Brown Mountain Beach are flooded. At 6.5 feet, 
the bridges at Brown Mountain Beach Rd. and Edgemont Rd. are 
beginning to be inundated by Wilson Creek floodwaters.

The river stage of the Johns River at Arney's Store was 12.22 feet. 
At 12 feet, parts of NC 90 north of Collettsville, Johns River Rd 
and Corpening Bridge Rd. are flooded.

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
other landmarks.

Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
759 PM EDT Tue May 29 2018

.SYNOPSIS...
Deep tropical moisture will persist over the area through Wednesday
as the remnants of Alberto move northward from Alabama to Kentucky
and eventually to the Great Lakes. A moist airmass will persist into
Friday before southerly flow shifts more to the west. Slightly drier
air will mix in from the west over the weekend.

&&

.NEAR TERM /THROUGH WEDNESDAY/...
As of 745 PM EDT...Bands of heavy rain continue to slowly pivot
NEWD, oriented N-S. This is resulting in some training with intense,
tropical downpours that is causing flooding. No changes to the Flash
Flood Watch is needed at this time. Hopefully, with loss of daytime
heating, instability will decrease and rain rates will follow. The
latest HRRR shows gradual diminishing of precip across the eastern
half of the CWFA thru the evening, but then shows redevelopment of
scattered and hopefully, less intense, showers to the west that
spreads over the NC mountains thru the night. So categorical PoPs
will continue along the Blue Ridge overnight. The severe threat
looks to be lowering, due to decreasing instability and shear. So,
localized flooding and mountain landslides over the higher terrain
will continue to be the primary concern as periods of heavy rainfall
are expected to continue through the near term period. With the
already saturated ground, even marginal wind gusts could easily
bring down a few trees. High temperatures will remain near normal
and low temps will stay above normal.

&&

.SHORT TERM /WEDNESDAY NIGHT THROUGH FRIDAY/...
As of 200 PM EDT Tuesday: By the start of the short term period
(Wednesday night), the remnant circulation of Alberto will be over
the midwest getting absorbed by a negatively-tilted shortwave trough
lifting out of the Northern Plains. Upper high in the western
Atlantic combined with the slowly merging Alberto/shortwave will
continue to keep a moist fetch from the Gulf across the Southeast
and toward the Southern Appalachians. The trough will slowly lift
through the period as the upper ridge works down over the Bahamas,
with the deep moisture lifting to the northeast as well. A lingering
shortwave embedded in the pattern will push up the OH/TN Valleys
Thursday night into Friday, bringing another push of precip to area.
At least at the start of the period, PW values remain anomalously
high with deep warm cloud processes. Keeping the Flash Flood Watch
in effect through 12z Thursday looks good for now, though the
additional round of convection Thursday afternoon across the
mountains might be enough to warrant another extension...confidence
just not high enough at this time with QPF in the 6-hr period from
18zThu-00zFri less than 1/2 inch (though with the antecedent
conditions, that might be all it takes). Problem is that instability
will increase, Thu afternoon, both the NAM and GFS are creeping
SBCAPEs upwards of 3000J/kg across the escarpment/foothills/adjacent
Piedmont which could seriously intensify convective rates.

That secondary wave of moisture gets caught up over the mountains
Thursday night into Friday morning and might have a slow start with
convective initiation initially across the Piedmont, but still
enough to increase afternoon Piedmont pops to high chance. Keep pops
going overnight across the mountains with likelies again by Friday
afternoon.

Should see a slow warming trend through the period, pushing 90 for a
high across the Piedmont by Friday afternoon and continued very
muggy (yuck)...heat indices might be pushing the mid-90s with the
dewpoints remaining quite high at around 70 degrees.

&&

.LONG TERM /FRIDAY NIGHT THROUGH TUESDAY/...
As of 155 PM Tuesday: A southern tier ridge centered over Texas
will try to briefly ridge into our region Friday night into
Saturday but make little progress.  A weak surface frontal boundary
settles southward through the area to provide a very modest airmass
change. However, a digging northern stream trough will approach the
southern and central Appalachians Sunday and then cross the
mountains on Monday. This feature will enhance convection at a time
when CAPE values will be low on Monday. However, looking at Sunday
PM the GFS has 2000 to 3000 CAPE over the western tip of NC and the
upper Savannah Valley at the time when the EC has the axis of trough
crossing our region. Minor vortices crossing our area on Sunday
afternoon could spark strong convection over NE GA and adjacent
areas. Highest POPs Sunday and Monday along with warmer temps than
what we have had recently.  Above climo maxes on Saturday will dip
below climo by Monday, but with mild nighttime mins continuing.

&&

.AVIATION /00Z WEDNESDAY THROUGH SUNDAY/...
At KCLT and elsewhere: An intense rain band with embedded tstms
oriented N-S across the GMU/GSP area continues to pivot
northeastward this evening. Widespread precip coverage ahead/east of
this line, but isolated to scattered to the west. There is still
enough instability for convection to linger into the evening, but
should gradually diminish in coverage overnight. Low cigs and some
fog is expected again overnight thru Wednesday morning, like the
last couple days. Little change in air mass for Wednesday aftn will
result in numerous showers and tstms again with peak heating, but
with slightly drier air starting to work in. CIGS should lift from
IFR to MVFR then scatter out somewhat to VFR by mid/late aftn. Winds
should favor a SE to S direction at all sites, but can be variable
at times around deeper convection.

Outlook: Expect continued rounds of scattered to widespread showers
and embedded thunderstorms along with low cigs and briefly reduced
vsbys as tropical moisture lingers through at midweek. Drier air begins
to move into the area towards the end of the week, with some degree
of diurnal convection expected.

&&

.HYDROLOGY...
Heavy rainfall over the past two weeks across much of the forecast
area, particularly the mountains, has set the stage for serious
flooding and landslide issues to possibly develop with any
additional tropical rainfall through mid-week. Numerical model
profiles exhibiting precipitable water values of 1.75 to 2 inches,
and deep warm cloud layers in excess of 12 kft, will make for highly
efficient heavy rainfall processes and further increase the threat
of flash flooding and river flooding. The latest 3/6 hour FFG
guidance values are generally running 2.0 to 3.5 inches and these
will be quite achievable in the expected waves of tropical rain
showers - especially across the higher terrain. Hydro problems will
likely continue through tonight, and possibly through Wednesday
night across the mountains.
