...FLASH FLOOD WARNING REMAINS IN EFFECT UNTIL 515 PM EST THIS 
AFTERNOON FOR GEORGETOWN COUNTY...

At 131 PM EST, Emergency management reported heavy rain across the 
warned area. Between 4.5 and 7 inches of rain have fallen. Flash 
flooding is already occurring. Water rescues have been reported.

This is a FLASH FLOOD EMERGENCY for Eastern Georgetown County. This 
is a PARTICULARLY DANGEROUS SITUATION. SEEK HIGHER GROUND NOW!

HAZARD...Life threatening flash flooding. Heavy rain producing
         flash flooding.

SOURCE...Emergency management reported.

IMPACT...This is a PARTICULARLY DANGEROUS SITUATION. SEEK HIGHER
         GROUND NOW! Life threatening flash flooding of low water
         crossings, small creeks and streams, urban areas,
         highways, streets and underpasses.

Some locations that will experience flash flooding include...
  Georgetown, DeBordieu Colony, Pawleys Island, Yawkey South Island, 
  Winyah Bay Entrance, Murrells Inlet, Graves, Oatland, Sampit, 
  Plantersville, North Santee, Rhems, Litchfield Beach, Lambert and

Area Forecast Discussion
National Weather Service Wilmington NC
1249 PM EST Sun Dec 17 2023

.SYNOPSIS...
A nor'easter will move up through the Coastal Carolinas today
with strong winds, heavy rain, and coastal flooding. Cold air
will pour into the region behind this system Monday night and
will remain until a return of seasonable temperatures Thursday
through Saturday.

&&

.UPDATE...
The latest high resolution guidance continues to show the
prospects for what could be an interesting late
morning/afternoon period with the potent storm system moving up
the coast. The warm sector/dry slot clearly seen on satellite
and radar imagery as well as lightning plots is making haste to
the north and this area should begin to enter our area in the
next couple of hours. The widespread/uniform rain shield will
transition to more of a convective pattern but may hold on
inland for a while. The aforementioned guidance still shows some
updraft helicity swaths moving across the area south to north
late morning through afternoon with this feature. Any rotating
cells will have to be watched carefully.

&&

.NEAR TERM /THROUGH TONIGHT/...
An array of advisories and warnings are on display for the
local ILM CWA and coastal waters. Guidance has been dictating an
intense low pressure system to affect the FA, with progged
barometric pressures in the 980s when it passes by. This will
result in a tightened sfc pg as 1 would expect. The onshore
winds, ENE-ESE winds will peak early afternoon thru sunset, from
south to north, as the low lifts northward. The wind advisory
for the immediate coast remains thumbs up with the potential for
50 mph wind gusts.

The dynamics aloft to also aid in the form of a closed upper
low that aids in the low's increasing intensity. Low level
winds in the 55 to 70 kt speeds will move overhead which will
create LLWS headaches for the aviation community. In addition,
convection may tap this, bringing it to the sfc as damaging
wind gusts, with SPC highlighting a SLGT Risk. Not fully bought
on the high res model potential convection and associated high
QPF amounts that are produced in a corridor from Georgetown
County to Robeson County. Have increased overall rainfall
amounts from this system to a range of 3.50 to 4.75 inches, with
locally 5 inch amounts possible especially within the mentioned
corridor. Expect the nuisance type flooding with grounds being
able to handle the 12+ hr rainfall given the D0 and D1 drought
areas across the ILM CWA. True, runoff will occur more readily
given vegetation basically now in a dormant phase. But for now,
will keep the FFA at bay, unless qpf is further refined upwards.

The positioning of the coastal trof/front remains the various
models poor performance. Still are in a disagreement with one
another of whether tp push it onshore and how far inland it
progresses. As a result, max temps today will be forecast in a
range from the 50s far west portions to the 60s to possibly near
70 at the immediate coast, again dependent of whether the
coastal front moves onshore and how far inland. Potential
temperature busts are high.

&&

.SHORT TERM /MONDAY THROUGH TUESDAY NIGHT/...
Stiff westerly flow on the back end of exiting storm system will
usher in plenty of dry and cold air. Temps starting out near 50
to 55 Mon morning will only rise several degrees in full
sunshine on Monday in deep CAA, but deep mid to upper trough
will cross the area Mon night into Tues. This will lead to
strong CAA with 850 temps dropping about 10 C down below -5 C.

&&

.LONG TERM /WEDNESDAY THROUGH SATURDAY/...
High pressure will continue to extend down from the north with
ridging building up through the Southeast through much of the
remaining week. After a very chilly start, temps will rebound
close to 50 most places. Air mass will modify slowly with mid
50s Thurs and reaching above 60 by the weekend with continued
dry weather. Overnight lows will be below freezing Wed night
again and will be in the mid 30s by Fri night.

&&

.AVIATION /18Z SUNDAY THROUGH FRIDAY/...
As anticipated it couldn't get much worse for the aviation
community this afternoon perhaps outside of a winter event or
hurricane. Strong coastal storm moving across today and tonight
with prevailing IFR to occasionally lower conditions. There
may be some relief later tonight with regards to visibilities,
but low ceilings are expected to linger. Mid to late morning
Monday may offer up MVFR to even VFR conditions. A couple of
final notes...wind shear is expected this afternoon along the
coast along with vcts although thunder is a little more iffy.

Extended Outlook...Flight restrictions expected early Mon along
with strong and gusty winds. This the result of the intense
storm system departing to the northeast. Dominant VFR conditions
should return later Mon and persist thru midweek with breezy
conditions lingering into Tue as high pressure ridges in.

&&

.MARINE...
Through Tonight...STORM WARNING, that's is correct, you didn't
read that wrong!! Intensifying low pressure system off the FL
east coast this morning, will track NNE along the coastal
trof/front, up the U.S. Southeast Coast today, reaching off Cape
Fear by this evening. Closed upper low will slow the sfc low's
forward speed slightly tonight but should be near Cape Hatteras
by daybreak Mon. Highest sustained and peak gusts will occur
today, under the E to SE wind direction. Hiest seas will also
occur today into this evening prior to the offshore wind
trajectory that occurs after the passage of the sfc low. Periods
will be low relatively speaking, ie the large seas(in double
digits) will not be long period like one observes ahead of
approaching tropical cyclones. In fact, "Victory at sea
conditions" will likely dominate.

Monday through Thursday...Strong offshore flow will continue as
intense coastal storm lifts off to the northeast. Winds will
continue to be gusting up to 40 kts Mon morning but will drop a
good 10 to 15 kts by aftn. Upper level trough digs down from
the north moving through Mon night. This will cause a bit of
rise in winds and seas Mon night with a slow improvement
afterwards, into midweek. Seas starting out 8 to 11 ft will drop
to 5 to 7 ft Mon night into Tues and dropping down below SCA
thresholds by Wed morning, down to 4 to 5 ft. Winds will veer
from NW to N through midweek around 10 to 15 kts.

&&

.TIDES/COASTAL FLOODING...
Minor flooding is still expected at both SC beaches and the
Lower Cape Fear. Guidance has backed off on the severity area-
wide but this seems suspicious with such a well defined and
still strengthening system. Overall the system is slower and so
too is the peak surge. This means it no longer coincides with
high tide at SC beaches but moderate flood still expected and
opted to remain closer to the upper end of PETS ensemble noting
there is considerable spread. The impressive 3 ft surge also
works its way up to NC but with even more delay after high tide.
Lowered the Watch to and Advisory but the current forecast of
7.8 at Mercer Pier still a noteworthy tide about on par with
Hurricane Ian or the nor'easter from Nov 2021.
