The radar

The Greer radar (KGSP), 56 km from the middle of the area, began a volume at 20:58 UTC, the scan nearest the moment this went out.

The archived warnings, watches and discussions in force at that minute are drawn over the scan, this one among them.

Did it verify

Not verified. The Iowa Environmental Mesonet's Cow found no qualifying storm report inside this flash flood warning while it was in force. That is not proof nothing happened: reports are thin where few people live.

Cow counts a report within 15 km of the polygon while the warning was in force: a tornado for a tornado warning; hail of 1 inch or more, a gust of 58 mph or more or wind damage for a severe thunderstorm warning; a flash flood report for a flash flood warning.

BULLETIN - EAS ACTIVATION REQUESTED
Flash Flood Warning
National Weather Service Greenville-Spartanburg SC
458 PM EDT TUE MAY 29 2018

The National Weather Service in Greenville-Spartanburg has issued a

* Flash Flood Warning for...
  Henderson County in western North Carolina...

* Until 600 PM EDT.

* At 454 PM EDT, gauge reports indicated heavy rain falling across
  the warned area. Flash flooding is likely occurring or will begin
  shortly.

* Some locations that will experience flooding include...
  Hendersonville, Mills River, Fletcher, Flat Rock, Etowah, Mountain
  Home, Laurel Park, B.R. Parkway-Mount Pisgah To The Nc Arboretum,
  Valley Hill and Horse Shoe.

* At Mud Creek, the latest stage was 7.5 feet. At this level, East 
  Caswell Street is flooded from storm culvert backwater effects 
  underneath the railroad tracks adjacent to Mud 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.

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 May 29, 2:51 PM EDT, 2 hours 7 minutes earlier.

Area forecast discussion, May 29, 2:51 PM EDT, 2 hours 7 minutes before
Area Forecast Discussion
National Weather Service Greenville-Spartanburg SC
251 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 230 PM EDT Tuesday: A Flash Flood Watch remains in effect for
the entire CWFA as abundant tropical moisture continues to stream
across the region. Subtropical Depression Alberto continues to make
gradual progression northward this afternoon as the latest satellite
imagery depicts the center of circulation over Northern Alabama.
We've seen an increase in thunderstorm activity over the past couple
of hours as sct breaks in the cloud cover have allowed sfc-based
instability to increase. This instability combined with some decent
low-lvl SRH in the 100 to 250 m2/s2 range, will keep a marginal risk
over the area for severe thunderstorms and isolated tornadoes. The
latest CAM guidance continues to develop numerous discrete cells
thru the late afternoon and into the evening. 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 /19Z TUESDAY THROUGH SUNDAY/...
At KCLT and elsewhere: A mixture of MVFR/IFR/LIFR will continue
across the area thru the 18z TAF period. We have seen some cloud
to ground lightning activity commence over the past couple of hours
and expect thunderstorm coverage will increase thru the afternoon
hours. Heavy downpours and gusty winds will be possible in stronger
storms thru the afternoon and into the evening. Shower coverage of
is expected to wane into the overnight hours, with mostly just rain
showers expected. Winds will remain out of the SE in the 5 to 10 kt
range and eventually veer around to a more SLY direction by tomorrow
afternoon.

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. Hydro problems will
likely continue through tonight, and possibly through Wednesday
night across the mountains.
