FLOOD WARNING 
NATIONAL WEATHER SERVICE BLACKSBURG VA  
937 PM EDT Sat Sep 15 2018

...The National Weather Service Blacksburg Va has issued
a Flood Warning for the following rivers in North Carolina...

  Yadkin River At Wilkesboro affecting Wilkes County
  Yadkin River At Elkin affecting Surry and Yadkin Counties

Moderate to Major flooding is forecast on the upper Yadkin River due 
to the rains expected from now Tropical Storm Florence. Rainfall of
5 to 10 inches with isolated higher amounts is forecast over 
the next 48 hours across the Yadkin basin. The forecast for these flood 
levels is based almost entirely on forecast rainfall. Should the rain 
that occurs be lower, flood levels will also be less and conversely if
the rainfall is higher then flood levels could exceed these forecasts. 
Updates will be made as necessary. 

Stages at Elkin could be the highest since W. Kerr Scott Dam was
completed in 1962 if this forecast verifies.

    
PRECAUTIONARY/PREPAREDNESS ACTIONS...

Do not drive through flooded areas...the water may be much deeper 
than you think.

Listen to noaa weather radio or your favorite media outlet for later 
statements or warnings.

FLOOD STATEMENT 
NATIONAL WEATHER SERVICE BLACKSBURG VA 
1013 PM EDT Sun Sep 16 2018

...The Flood Warning is cancelled for the following rivers
in North Carolina...
 
  Yadkin River At Wilkesboro affecting Wilkes County
 
...The Flood Warning continues for the following rivers in North 
Carolina...
 
  Yadkin River At Elkin affecting Surry and Yadkin Counties 

Rainfall in the upper Yadkin River basin has been lower than
previously forecast and forecast rainfall overnight has also 
been reduced as the heaviest rain bands from Florence have 
shifted just east of the basin. As a result no flooding is
expected at Wilkesboro and the severity of flooding at Elkin will
be lower as well. Depending on overnight rains this forecast

What forecasters said that day

The local office's own words before this river flood warning went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Blacksburg, VA wrote its last area forecast discussion before this river flood warning went out at Sep 15, 4:02 PM EDT, 5 hours 35 minutes earlier.

Area forecast discussion, Sep 15, 4:02 PM EDT, 5 hours 35 minutes before
Area Forecast Discussion
National Weather Service Blacksburg VA
402 PM EDT Sat Sep 15 2018

.SYNOPSIS...
Florence will continue to track inland into South Carolina
tonight before passing northward across the southern
Appalachians and into the Ohio Valley Sunday through Monday.
Periods of rain and gusty winds will accompany this system
bringing the threat of significant flooding by Sunday into
Monday.

&&

.NEAR TERM /THROUGH SUNDAY NIGHT/...
As of 330 PM EDT Saturday...

Another band of showers with heavy rainfall will continue to work
through southern sections into early this evening before perhaps
seeing a lull. However deeper moisture to the north of Florence
should push northwest into southwest sections overnight with heavier
rainfall mainly south of I-81 by daybreak Sunday. This may result in
1-3 inches across the NC mountains by early Sunday if banding
develops as upslope remains limited given east/northeast flow. This
should also help to reduce rainfall northeast of the Blue Ridge
where the wedge looks to hold. Other concern with surge in winds
overnight as the low level jet ramps up to 50 kts across southwest
sections with some potential for stronger banding to mix these winds
down. Toyed with upping the going wind advisory to a warning for the
NC ridges but given more easterly flow opted to only boost speeds
for now as expect the higher speeds to remain on the ridgetops.
However since latest guidance shows a swath of higher winds swinging
north overnight, will expand the wind advisory up to the western New
River Valley and include parts of southeast West Va per downsloping.
Otherwise pops ramping up from southwest to northeast overnight with
categorical to likelys in store but without much thunder mention.
Lows muggy under steady northeast flow with readings mainly in the
60s to around 70 overnight.

Main aspect of Florence will play out across the area Sunday into
Sunday night as the core of the system passing by to the southwest.
As the system turns more north, an axis of strong convergence looks
to develop likely along the ongoing main rainband that looks to work
up from the south as depicted by most solutions. If this and
subsequent bands gets pinned along the southern Blue Ridge then will
see excessive rainfall even without a good upslope component until
Sunday evening. Models tend to agree on QPF through the Sunday
period with several inches along the eastern slopes of the Blue
Ridge. Winds again likely an issue either ahead or with this main
stronger band given more deeper convective potential along with
isolated tornadoes espcly with rotating cells within the linear
banding so something to watch. Only small temp rises with highs
mostly in the low/mid 70s.

Rainfall will likely become more upslope oriented Sunday night with
the main axis of lift spilling east of the mountains after midnight
as suggested by the latest ECMWF. Still another 1-3 inches possible
along the Blue Ridge early on before the heavier rain band pivots
into eastern sections late. Banding features along with more south
to southerly flow could again promote more spin up potential that
will evolve east during the evening as soundings show quite a bit of
helicity as the flow quickly veers with the passing banding.
Otherwise continued high pops including an expansion of the flash
flood watch along the New River and into Mercer county where have
been wet of late. Lows again mainly 60s to around 70.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
As of 330 PM Saturday...

Post-tropical remnants of Florence expected to eject along with
a lead swath of heavy rainfall across the central-northern
Mid-Atlantic and northeastern states Monday and Tuesday. In the
wake of this system, high pressure will return for mid-week.

There are still model differences with respect to timing which
may speed up or delay the system from exiting the region Monday
and Tuesday, but consensus is the majority of the excessive
rainfall will fall prior to noon Monday for our forecast area
followed by a more showery form of rainfall as we progress
through Monday night and Tuesday. Pending wind/shear profiles,
there is still potential for isolated tornadoes Monday
associated with the right quadrant of the storm system, but the
greatest impacts will be focused on the hydrology aspect with
many streams/rivers expected to go into flood or be in flood at
that time.

Temperatures will remain mild through the forecast period,
dewpoints also remaining elevated. No big change in airmass is
anticipated as we will go right back under the influence of the
late summer subtropical ridge.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
As of 345 PM EDT Saturday...

Subtropical ridge of high pressure is forecast to build back
across the southeastern CONUS with temperatures favoring above
normal readings for the remainder of the week. Dewpoints will
also remain elevated, so anticipating summer-like conditions as
we progress through the 3rd week of September. A cold front will
approach late in the week providing an uptick in shower/storm
chances in the Friday/Saturday time frame.

&&

.AVIATION /20Z SATURDAY THROUGH THURSDAY/...
As of 1250 PM EDT Saturday...

Shower bands decreasing across the region this afternoon as main
core of the tropical moisture slips a bit south closer to the
center of Florence. However with added banding developing just
south of the region, expect some of these showers to return to
at least southern sections in the next couple of hours. This
supported by several model solutions in keeping most of the
heavier rainfall confined to along the VA/NC border before
gradually heading northwest into southwest sections of the area
this evening/overnight. Otherwise looking at overall MVFR cigs
into late this afternoon with sporadic reductions in vsby to
brief sub-VFR in light showers, mainly Blue Ridge sites east, except
perhaps some heavier rainfall near KDAN later this afternoon.
Western locations should see little in the way of showers and
could see intervals of VFR develop espcly around KLWB into early
this evening.

Expect northeast winds to remain strong at times across the
entire area, with highest gusts to 30-35kts possible within
showers.

More widespread showers becoming moderate to heavy expected by
02-06z mainly south of a line from KBLF-KROA_KDAN, but likely
staying southwest of KLYH until Sunday. Otherwise conditions
stay poor for flying with low cigs across the region and
lowering vsbys due to rain/fog and mountain obscuration.

Should see widespread periods of showers with heavy rainfall
espcly southern/western sections Sunday with strong easterly
winds perhaps gusting over 35-40 kts at times within rain bands.

There is high confidence in sub-VFR conditions through most of
the period.

Extended Discussion...

Rainfall will become more showery Sunday night and Monday as the
remnants of Florence pass to the northwest before exiting the
region. This will keep overall sub-VFR in place Sunday night,
improving to only periods of MVFR/IFR by Monday afternoon. Winds
will swing to the southeast by Sunday night then to the
southwest to west early next week. Will finally see Florence
shift north of us by Tuesday of next week with conditions
improving. VFR conditions are then expected for Wednesday and
Thursday with high pressure over the area.

Confidence gradually transitions to average Sunday night into
Monday the above average by the middle of next week.

&&

.HYDROLOGY...
As of 400 PM Sunday...

Latest model output and coordination with WPC continues to suggest
heavy rainfall across at least the southern half of the region with
much of this occurring tonight into Monday. Rainfall rates and
totals will likely be higher across northwest North Carolina as
deeper banding occurs just to the northeast of Florence by Sunday.
Still looking at up to 10 inches along the Blue Ridge with locally
heavier totals pending just how the bands pan out. Elsewhere,
appears that a wedge of high pressure aided by strong northeast flow
may tend to lessen rainfall rates heading north into parts the James
River basin until the cool pool exits by early Monday. This would
support less rainfall heading north until things become more banded
and convective in nature on Monday. However rainfall exceeding 5
inches appears likely espcly along and east of the Blue Ridge in
Virginia including the Roanoke River basin.

RFC guidance available on the AHPS web page is showing moderate to
major flooding along the New, Roanoke and Dan Rivers occuring over
the next 1 to 3 days and these graphics have been widely shared.
While this certainly remains a strong possibility if the QPF
verifies, no River Flood Warnings have been issued due to persisting
questions remain as to the placement and amount of QPF. A small
shift in track and amounts can have a huge impact on the hydrologic
forecasts. But a warning for the Dan River is likely to be issued by
this evening as confidence in amounts is highest and the crests will
be soonest at least in the upper reaches of the river.

The flash flood watch was also expanded in southwest Virginia to
include Bland, Giles, and Tazewell counties and in southeast West
Virginia, Mercer County.
