...COASTAL FLOOD ADVISORY REMAINS IN EFFECT UNTIL 10 PM EDT THIS
EVENING...
...HIGH SURF ADVISORY REMAINS IN EFFECT UNTIL 5 AM EDT MONDAY...
...BEACH HAZARDS STATEMENT IN EFFECT FROM 8 AM EDT MONDAY THROUGH
MONDAY EVENING...

* WHAT...For the Coastal Flood Advisory, 1 to 2 feet of inundation
  above ground level in low-lying areas near shorelines and tidal
  waterways. For the High Surf Advisory, large breaking waves of 5
  to 9 feet in the surf zone. For the Beach Hazards Statement, 
  dangerous rip currents and strong longshore currents in the surf
  zone.

* WHERE...West Carteret, East Carteret and Coastal Onslow 
  Counties.

* WHEN...For the Coastal Flood Advisory, until 10 PM EDT this 
  evening. For the High Surf Advisory, until 5 AM EDT Monday. 
  For the Beach Hazards Statement, from 8 AM EDT Monday through 
  Monday evening.

* IMPACTS...Flooding of lots, parks, and roads with only isolated
  road closures expected. Dangerous swimming and surfing
  conditions and localized beach erosion. Rip currents can sweep
  even the best swimmers away from shore into deeper water.
  Dangerous shore break can throw a swimmer or surfer head first
  into the bottom causing neck and back injuries. Strong longshore
  currents will create dangerous swimming conditions.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

If travel is required, allow extra time as some roads may be
closed. Do not drive around barricades or through water of
unknown depth. Take the necessary actions to protect flood-prone
property.

Inexperienced swimmers should remain out of the water due to
dangerous surf conditions.

Life-threatening rip currents. If caught in a rip current, remain
calm. Swim in a direction following the shoreline. If tired,
float or tread water until out of the rip current. If unable to
escape, face the shore and call or wave for help. 

Shore break occurs when waves break directly on the beach. It is 
extremely important to protect your head and neck whenever you are 
in breaking waves by keeping your hands in front of you at all times.

Strong longshore currents can sweep swimmers and surfers into rip
currents, piers, jetties and other hazardous areas. In many
cases, the longshore current is strong enough to prevent swimmers
from being able to keep their feet on the bottom making it
difficult to return to shore.

National Weather Service Newport/Morehead City NC
701 PM EDT Sun Apr 30 2023

.SYNOPSIS...
A strong and wet storm system moves up the East Coast today
into Monday. Drier and cooler weather is then expected through
mid week as high pressure builds into the Eastern CONUS.

&&

.NEAR TERM /THROUGH TONIGHT/...
As of 7 PM Sun...Svr threat ended quickly across eastern NC
late this afternoon with deeper convection pushing offshore.
Scattered light showers expected for the next few hours, with
best chances across the northern forecast area. Dry air will
quickly filter in from the west as today's upper level low
departs the area this evening. Modest winds aloft, some residual
mixing, and a modest pressure gradient should support a
continuation of breezy conditions from this afternoon. Despite
the wind, temperatures should still be able to fall into the 40s
and 50s tonight thanks to strong cold air advection behind
today's cold front.

&&

.SHORT TERM /MONDAY/...
As of 130 PM Sunday...On Monday, a dry westerly flow in tandem
with cool temps aloft will support modest mixing and continued
breezy conditions. Despite lower than normal thicknesses, the
downsloping flow will probably offset how cool it otherwise
could be. Regardless, the drop in temps and humidity will be
noticeable.

&&

.LONG TERM /MONDAY NIGHT THROUGH SUNDAY/...
As of 425 AM Sun...Today's low will occlude and linger over the
Great Lakes for the first half of the work week before high
pressure eventually wrestles back control over the region.
Cooler than average conditions are expected through most of the
period before moderating back to climatological norms for the
weekend with another potential weekend of unsettled weather.

Monday night through Wednesday...Primarily dry and cooler than
average conditions hold over eastern North Carolina through the
first half of the work as the surface low occludes over the
Great Lakes and meanders over the region through Wednesday.
While the low stays in place, the resultant pressure gradient
will result in healthy southwest to westerly winds during the
afternoons with gusts up to 25 kt. Tuesday will be the windiest
days, perhaps slightly more than Monday as an embedded
shortwave pivots around the parent upper low and aids in driving
a surface trough across the region. With min RHs ranging from
30-35%, fire weather will be a concern. By Wednesday, the upper
low will begin to shift towards the North Atlantic and winds
will abate somewhat, although still gusting up to 20 kt at
times.

The 00z guidance this morning, particularly the ECMWF, is
highlighting the potential for some afternoon showers on Tuesday
afternoon ahead of the surface trough and associated embedded
shortwave. The GFS remains less enthusiastic but still squeezes
out some isolated activity. Will keep forecast dry for now given
how recent these trends are, but pattern would favor some light
showers or sprinkles given somewhat steep lapse rates.

Thursday through Saturday...By Thursday, the surface low will
have lifted out over the North Atlantic allowing high pressure
to take more dominant control. Model guidance diverges beyond
then, although ensembles hint at a return to some unsettled
weather as a weak cold front develops across the Central Plains
and TN Valley with weak low pressure riding along it. Any signal
in place this time yesterday is now more diffuse, and opted to
reduce PoPs to slight chance for the weekend rather than
favoring any one particular day.

&&

.AVIATION /00Z MONDAY THROUGH FRIDAY/...
SHORT TERM /through Monday/...
As of 7 PM Sun...Mix of MVFR and VFR across the terminals early
this evening. Could see periods of MVFR through 03z with isolated
to scattered showers, with conditions becoming pred VFR after.
Gusty SW winds diminish a bit this evening, becoming W tonight,
then gusting 20-25 kt Mon.

LONG TERM /Monday night through Friday/...
As of 430 AM Sun...VFR conditions are expected through the
period. Main aviation concern will be gusty winds, particularly
Monday through Wednesday, as lingering low pressure to our north
keeps the pressure gradient tight. Southwest to westerly winds
will gust to 25+ kt each afternoon.

&&

.MARINE...
SHORT TERM /through Tonight/...
As of 7 PM Sun...Latest obs show strong SW/WSW winds 20-30 kt
with gusts 25-40 kt and dangerous seas. Strong southwesterly
winds will continue through early this evening, then will
switch to a westerly direction in the wake of a cold front
moving through. Strong, gusty winds will continue well into
Monday, but won't be quite as strong as what is occurring now.
Gales and SCAs continue for the waters and sounds. Winds and
seas will come down some tonight as the flow becomes westerly,
but it will be a gradual lay down. The winds and seas won't
completely lay down, though, given the continued gusty winds
into Monday.

LONG TERM /Monday night through Friday/...
As of 435 AM Sun...Persistent SCA conditions will continue at
least through Tuesday night as the surface low lingers over the
Great Lakes keeping the pressure gradient tight over the waters.
The strongest winds in the period are expected on Tuesday ahead
of an approaching coastal trough with southwesterly winds
gusting up to 30 kt. Some of the latest hi- res guidance is
favoring a small window of Gales, particularly for Raleigh and
Onslow Bays and this will be monitored for potential headline
upgrades in subsequent shifts.

After the rapid building expected today, seas will have fallen
to around 5-8 feet by Monday morning. The persistently higher
winds will keep seas around these levels at least through
Tuesday night, before weakening winds on Wednesday eventually
allow seas to ease below 6 feet by the end of the period. The
highest seas are expected for outer portions of Raleigh Bay,
with heights up to 8-9 feet.

&&

.FIRE WEATHER...
As of 7 PM Sun...Behind strong low pressure system tomorrow
morning, cooler and drier high pressure will move into the area
through most of this week. While this occurs, a large and
occluded low pressure system will sit over SE Canada, and keep a
strong pressure gradient intact across the Carolinas through
Wednesday.

RH values will drop to at least 30%-35% each afternoon, while
southwesterly to westerly winds remain strong at 15-20 mph with
gusts of 25-30 mph. The strongest winds are expected Tuesday
afternoon ahead of a surface trough pivoting around the parent
low. Deep mixing may promote even stronger wind gusts at times.
Winds will weaken somewhat on Wednesday while veering
northwesterly behind the trough, but could still gust up to 25
mph at times.

&&

.TIDES/COASTAL FLOODING...
As of 7 PM Sun...A brief but potent surge of SW/WSW winds
continues this evening, with many gauges along the soundside
Outer Banks beginning to show increasing water levels. Despite
the short duration of the winds, some minor soundside flooding
of 1 to 2 feet is probable with the most vulnerable areas being
soundside Outer Banks north of Cape Hatteras. Water rises of
similar magnitude are also possible for waterways along the
Crystal Coast. Coastal Flood Advisories have been issued for
these areas. Water levels will likely peak this evening.

In addition to flooding, dangerous surf conditions are likely to
continue into early Monday. The most vulnerable beaches will be
Sern facing beaches, predominantly from Cape Hatteras south,
and could lead to localized overwash and dune erosion. A High
Surf Advisory remains in effect for these zones until early
Monday morning.
