...THE FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 200 PM EDT FOR
SOUTHEASTERN YANCEY COUNTY...

At 1130 AM EDT, Automated rain gauges indicated as much as 5 inches 
of rain had fallen in parts of the Black Mountains for this event. 
Excessive runoff will continue to filter through the Cane and South 
Toe River basins.  Additional heavy rain is likely to fall across 
the warned area through early afternoon.  

Some locations that will experience flooding include...
Mount Mitchell State Park, Celo, Busick, Micaville and B.R.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

Runoff from heavy rain into creeks and streams will cause sudden
increases in water levels and flows, even in areas where rainfall has
been light or nonexistent. Hikers, campers and other individuals
outdoors must immediately seek high ground and avoid all streams.

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.

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.

Runoff from heavy rain into creeks and streams will cause sudden
increases in water levels and flows, even in areas where rainfall has
been light or nonexistent. Hikers, campers and other individuals
outdoors must immediately seek high ground and avoid all streams.

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.

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 Sep 16, 7:12 AM EDT, 2 hours 57 minutes earlier.

Area forecast discussion, Sep 16, 7:12 AM EDT, 2 hours 57 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
712 AM EDT Sun Sep 16 2018

.SYNOPSIS...
The remnants of Florence will continue to track into and through the
western Carolinas this weekend. This will result in a threat for
widespread flooding into Monday. Drying will occur across the
forecast area as Florence pulls away from the southeast early next
week with the rain chances returning towards the end of the week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 645 AM EDT: The center of Florence continues to crawl slowly
westward near Columbia. Rain continues to wrap around the northern
half of the storm and across our area, but rates have been generally
modest. That said, there have been some brief heavy amounts. The
heavier rain rates are off the the east but will move in as the
center of Florence moves west this morning then NW this afternoon.
The strong low level flow becomes more easterly increasing the
orographic component and keeping moisture transport high. Given the
forecast track, the heaviest rainfall will be from along the NC/SC
border north across the Foothills and Piedmont to along and near the
Blue Ridge Escarpment. Additional rainfall of up to 6 inches will be
possible across these areas today and tonight. Rainfall drops off to
the SW with one-half to one inch from the Upper Savannah River
Valley north into the SW NC Mountains. 1 to 3 inches may fall
between these two areas. The Flash Flood Watch likely extends too
far west. However, don't want to cancel any portions just yet since
the heaviest rain rates are yet to come.

Wind gusts up to 50 mph will become more widespread this morning as
the stronger winds spread in from the east. Therefore, will extend
the Wind Advisory through the day today but portions of the advisory
may be able to be cancelled early.

The tropical tornado threat has increased somewhat this afternoon
and early evening. 0-1 km helicity remains quite high with the
strong low level jet in place. The change is an increase in muCAPE
across the I-77 corridor into the NC Foothills. SPC has upgraded
this area into the Marginal category as a result.

Precip chances, and resulting threats, taper off from SW to NE
overnight. Highs today will be 5 to 10 degrees below normal, while
lows tonight will be 5 to 10 degrees above normal.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 345 AM EDT Sunday: A Flash Flood Watch remains in effect for
portions of the area through Monday evening.

Model guidance remains in fairly good agreement with the placement
of what will be post-tropical Florence over Kentucky Monday morning,
as the system is progged to weaken and become an open 500 mb wave by
late Tuesday. As it propagates up towards the Ohio River Valley but
then pushes eastward with sfc trough, lingering wrap around moisture
will allow for isolated showers to persist across the FA through
Tuesday late afternoon/evening, gradually tapering off from south to
north. Additional rainfall amounts of a quarter of an inch or less
are possible. Overnight Tuesday, PoPs drop off below mentionable wx,
and thus the drying trend begins. Temperatures throughout the short
term will remain just above normal.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 350 AM EDT Sunday: Not much has changed in regards to the
extended forecast period from earlier today, as latest guidance
continues to depict the expansion of high pressure into the
Southeast on Wednesday. Expect this feature to linger through the
end of the week, as guidance depicts the ridge of high pressure
shifting from across the Carolinas and into the Atlantic. As a
result, south-southeasterly flow returns and so does the
infiltration of moisture into the area ahead of an approaching front
from the northwest. Thus, would not entirely rule out a few diurnal
showers as early as Thursday, mainly across the mountains. As the
boundary moves closer to the FA, expect the potential for showers
and thunderstorms to expand across the entire area beginning Friday
afternoon and continuing through the weekend. Rainfall amounts will
be minimal. Temperatures will remain above normal.

&&

.AVIATION /11Z SUNDAY THROUGH THURSDAY/...
At KCLT and elsewhere: Very gusty NE winds will continue across the
area this morning. IFR ceilings are expected by daybreak with IFR
vsby east and MVFR west where the heavier rainfall moves in. IFR
cigs continue through the day with IFR vsby for all but KAND where
rain will be lighter. Gusty NE winds continue as well, but speeds
drop off from west to east during the afternoon. Winds diminish even
more during the evening and turn ESE to SE as the the weakening
center of the Florence remnant moves north across the area.

Outlook: Expect intermittent MVFR or IFR flight restrictions with
periods of moderate to heavy rain early Monday as the remnants of
Florence move north of the western Carolinas. Flight conditions
improve later on Monday and into Tuesday.

...AN AREA OF HEAVY RAIN WILL IMPACT CABARRUS...MECKLENBURG...ROWAN
AND UNION COUNTIES UNTIL 830 AM EDT...

At 652 AM EDT, Doppler radar indicated the leading edge of an
incoming band of heavy rain along a line extending from 8 miles
southeast of Salisbury to near Monroe, and moving northwest at 40
mph. The band of rain extends farther southeast into northern South
Carolina, and the heavy rain will persist across the Charlotte Metro
area for some time. Expect increased ponding of water and some rises
on area waterways. As the rain continues to fall, Flood Advisories
or Flash Flood Warnings may be needed over the next few hours.
Residents and motorists are urged to exercise extreme caution today.

Locations to be impacted include...
Uptown Charlotte, Huntersville, Kannapolis, Downtown Concord, Monroe,
Salisbury, Central Charlotte, South Charlotte, Northeast Charlotte
and Southwest Charlotte.

Wind gusts up to 40 mph and very heavy rainfall rates up to 2 inches
per hour will be possible in these areas.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

The combination of gusty winds and saturated soil conditions will
cause scattered trees and power lines to fall. Seek shelter inside an
interior room.

Torrential rainfall may flood areas with poor drainage, such as
ditches and underpasses. Avoid these areas and do not cross flooded
roads. Water levels of small streams may also rise rapidly. Seek
higher ground if threatened by flood waters.

These heavy rain may intensify, so be certain to monitor local radio
and tv stations, as well as local cable tv outlets for additional
information and possible warnings from the National Weather Service.
