* Coastal Flooding...The downtown Wilmington tide gauge should peak 
  near 5.65 ft MLLW.

* Timing...The highest water levels are expected between 430 AM and 
  630 AM Tuesday.

* Impacts...Several inches of water will cover portions of U.S.S.

...HIGH RIP CURRENT RISK IN EFFECT THROUGH THIS EVENING...

The National Weather Service in Wilmington has issued a High Rip
Current Risk, which is in effect through this evening.

* Location...Horry and Georgetown County beaches.

* Rip Current Risk...High.

* Surf Height...3 to 5 feet at Horry and Georgetown County beaches.

* Timing and Tides...Strong rip currents could occur at any time, 
  but will be especially prominent several hours either side of low 
  tide.

* Other Hazards...Strong and rough surf. Significant beach erosion 
  possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

There is a high risk of rip currents. Life threatening rip currents
are likely in the surf zone.

Rip currents are powerful channels of water flowing quickly away
from shore, which occur most often at low spots or breaks in the
sandbar and in the vicinity of structures such as groins, jetties
and piers. Heed the advice of lifeguards, beach patrol flags and
signs.

If you become caught in a rip current, yell for help. Remain calm,
do not exhaust yourself and stay afloat while waiting for help. If
you have to swim out of a rip current, swim parallel to shore and
back toward the beach when possible. Do not attempt to swim directly
against a rip current as you will tire quickly.

What forecasters said that day

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

NWS Wilmington, NC wrote its last area forecast discussion before this rip current statement went out at Apr 24, 3:23 AM EDT, 1 hour 52 minutes earlier.

Area forecast discussion, Apr 24, 3:23 AM EDT, 1 hour 52 minutes before
Area Forecast Discussion
National Weather Service Wilmington NC
323 AM EDT Tue Apr 24 2018

.SYNOPSIS...
Wet and windy conditions will prevail today as a storm system
impacts the region. Hazardous surf and minor coastal flooding
can also be expected through tonight. Drying and warming will
follow Wednesday in wake of the exiting system. Weak waves of
low pressure will bring isolated showers Thursday night through
Saturday, with mild, seasonable temperatures. High pressure is
expected to bring dry conditions, with highs in the 70s Sunday
through early next week.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 323 AM Tuesday...Stacked low over the TN Valley this
morning is resulting in deep south-southeast flow and strong
moisture advection across the area. Although the event was slow
to develop, the ingredients for significant rain have remained
in place and over the last few hours heavy rain has spread over
the area. Plume of deep moisture supporting the heavy rain will
continue to lift north, ahead of the occlusion. The 850 mb Theta
E ridge, currently just downstream of the area, will rotate
north this morning and cut off the deep moisture feed. However,
until this happens strong divergence aloft coupled with
increasing low level convergence will lead to a period of heavy
rain, lingering along the NC coast beyond sunrise. Strong and
gusty winds will start winding down along the SC coast shortly
while along the NC coast the 50kt low level jet is likely to
linger into the mid-morning hours before weakning.

Dry slot wraps into the area during the morning as the 5h trough
axis/cutoff slowly rotates toward the region. Forecast soundings
this afternoon show an abundance of dry air aloft. Heights will
be falling as the 5h trough axis slowly makes its way east, but
confidence is not high on potential for convection from midday
through early evening. Latest guidance keeps the trough axis
farther west until late tonight, well after peak heating,
suggesting the best diurnal activity may end up west of the
forecast area. Above 10k ft this afternoon and evening RH in
forecast soundings does not exceed 50% (and is mostly at or
below 30%). Despite these negative factors there is limited
potential for the development of deeper convection. Flow remains
southerly, ensuring warm and moist boundary layer. Breaks of
sun could easily push highs into the upper 70s away from the
coast. Afternoon showers and isolated thunderstorms cannot be
ruled out, but coverage will limited.

Any convection that is able to develop will quickly weaken with
the loss of heating. Mid-level trough moves across the area late
tonight, but the loss of diurnal instability will prevent any
convection with the trough. Not much in the way of cold
advection during the period despite the passage of the cold
front this morning. Temperatures will be near to slightly above
climo this afternoon and linger several degrees above climo
overnight.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
As of 323 AM Tuesday...A cold pool aloft will be sliding ENE
across central NC daybreak Wednesday, associated lapse rates
and partial late April sunshine should help blossom daytime
showers, mainly across NC. Meanwhile, a snap-back to zonal flow
through afternoon may aid bringing maximums right to average
for the season, upper 70s. Thursday fair and quiet, until an
amplified smaller scale trough pivots NE over our interior
late Thursday night. Although timing is coincident with diurnal
cooling, mid-level lapse rates will sharpen, and an isolated
TSTM cannot be ruled out near the I-95 corridor, where the
instability aloft will be highest.

The surfzone still recovering, may carry strong rip currents
through the day Wednesday.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
As of 300 PM Monday...Another area of low pressure may bring
showers to the area Thursday into Friday. Otherwise, the long
term looks dry with temperatures near or slightly below seasonal
normals. Normals for this time of year run mid to upper 70s by
day and mid 50s overnight.

&&

.AVIATION /06Z TUESDAY THROUGH SATURDAY/...
As of 06Z...Widespread MVFR and IFR likely into mid-morning.
Very  heavy rain and possibly an isolated thunderstorm will
occur generally through 07-10Z, possibly through 12Z at

30 kt possible. As winds veer to the southeast this morning,

.MARINE...
NEAR TERM /THROUGH TONIGHT/...
As of 323 AM Tuesday...Gale warnings remain in effect for all
zones, although gale conditions should be subsiding across SC
waters during the next few hours. Low level jet will start to
weaken as the precip shield slowly shifts north, which should
lead to rapidly decreasing wind speeds. Flow will remain out of
the south today, becoming southwest this evening and overnight.
Weakening gradient will allow wind speeds to drop under 20 kt by
late morning and down to 10 to 15 kt for the evening and
overnight period. Double digit seas this morning will start to
subside as winds veer to southerly and weaken. Seas are likely
to remain above 6 ft for much, if not all, of the day and a
Small Craft Advisory is likely to be raised as the Gale Warning
is cancelled from south to north during the mid to late morning
hours.

SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
As of 323 AM Tuesday...A recovering ocean after being roughed
up considerably, may require the SCA extend into portions of
Wednesday, although winds should hold at 20 kt or less, from the
SW ahead of a surface front. The front will bring a wind-shift
to N 10-15 kt early on Thursday. No TSTMS expected this period
but a few marine showers possible. Aside from the SW wind-
waves, a diminishing SE swell of 9-11 seconds will prevail in
wake of the recent storm. Thursday shaping up to be a decent
marine day, in light wind, and subsiding seas.

LONG TERM /FRIDAY THROUGH SATURDAY/...
As of 3 PM Monday...SW winds on Friday. Speeds currently look
to run about 15 KT, becoming W Saturday.
