Synopsis for coastal waters from surf city north carolina to south santee river south carolina out to 20 nautical miles.. The remants of jose will spin nearly stationary off the new england coast the next several days while slowly weakening. Winds and especially seas will increase and build through the weekend into early next week as hurricane maria moves between the east coast of the u.s. And bermuda, producing hazardous marine conditions.

Building high pressure aloft from the north will bring dry but
warm air across the carolinas this weekend. Strong rip currents
and large surf along the beaches, as well as hazardous marine
conditions offshore will continue as hurricane maria moves
northward through the atlantic waters. The latest forecast puts
maria just over 400 miles east of the tip of CAPE fear by mid
week next week.

Near term through Saturday
As of 300 pm Friday... Since convection is struggling through the
window of maximum insolation, diurnal cooling with our lowering ball
of fire will put the curtail on convection into the late afternoon
to early evening, leaving a clear sky tonight as the cumulus
dissolves into the evening sky. Under clear skies and decelerating
winds, patches of fog can be expected between 4am and 8am. Minimums
will settle to 65-68 across most locals and low 70s near the beaches
and icw. The surfzone and area beaches will begin to possess a
hazard as long period SE swell from distant marie intensifies rip
currents, while creating large and powerful breakers near shore.

This will pose a threat to surf- waders, and even small children or
elderly not in the water but standing by the oceans roar, where wave
run-up can be speedy and strong, as wave periods will be on the
order of 15 seconds, representing a high translational velocity into
the surfzone. It is beyond this period however, namely Sunday, that
the surf becomes large. For Saturday 4-7 ft breakers, and a 'high-
risk' of rip currents along all beaches.

Short term Saturday night through Sunday night
As of 300 pm Friday... Although the weather will remain quiet,
the seas and surf will not. The main impact this weekend will
come from high surf and strong rip currents at the beaches.

Otherwise, jose will continue to churn in the northern atlantic
and maria will continue its trek northward, while high pressure
moves slowly east across the great lakes. The carolinas will
basically be under the influence of high pressure in the
northeasterly flow between these systems. A weaker gradient
flow initially will allow the sea breeze to dominate closer to
the coast helping to produce a greater on shore flow Sat eve.

The pcp water values will be near 1.3 inches closer to the coast
and down near an inch in a drier NE flow Sat eve, but a boundary
from jose will shift south overnight Sat into early sun. This
will produce some clouds and perhaps a spotty shower over the
waters. Otherwise expect mainly clear to partly cloudy skies and
overnight lows in the mid 60s most places.

The winds will pick up on Sun as gradient tightens with
northerly movement of maria which should reach about 500 to 600
miles to the southeast, but coastal carolinas will remain in dry
air and subsidence as ridge builds down over the area aloft and
we remain on back side of extreme outer periphery of maria. H5
heights will be up near 588 dm with 850 temps up near 16 to 17c.

This will help to keep a dry forecast with warm temps up in the
mid 80s for Sunday. Models show a some drier air advecting in
overnight Sunday with slightly lower dewpoints which may shave a
couple of degrees off overnight low, but still expected in the
mid 60s.

Long term Monday through Friday
As of 300 pm Friday... Hurricane maria will be slowly making its
way north well off the coast of the carolinas through the first
half of the week. Expected impacts will be dangerous surf and
an elevated rip current risk from long period (15 sec) swells.

This swell energy will translate into breaking waves as high as
10 to 15 feet along the beaches of new hanover and pender
counties, and 6 to 10 feet along the beaches of brunswick, horry
and georgetown counties into Wednesday. The swell energy should
begin to ease late Wednesday, but dangerous surf and an
elevated rip current risk will likely continue into Friday.

Northeast to north winds will be breezy along the coast, and gust
occasionally into the 20-30 mph range by Tuesday-Wednesday. It will
be a tough call at this point to determine how much peripheral
moisture from maria will affect the area, however it is reasonable
to expect for the ilm cwa, that SE nc will have the best chance for
precipitation based on the current forecast track of maria. The
highest pops, which will still remain less than 30% at this time,
will be Tuesday into Wednesday, before the cyclone gets picked up by
the westerlies on Thursday as indicated by both the GFS and ecmwf.

Upper level ridging and subsidence west of the hurricane will likely
result in a sharp sky cover gradient and temperatures remaining a
few degrees above normal through the week.

Aviation 21z Friday through Wednesday
As of 18z... Afternoon cumulus of sct-bkn050 will prevail
along the coastal interior with vcsh by mid afternoon. Any
convection should dissipate after 00z this evening. A light
onshore wind will guide the sea breeze front inland, and along
this boundary is where a shower or storm will be favored. High
pressure over the great lakes will push drier air southwestward
today and Saturday.VFR conditions this evening may decrease to
MVFR ifr again late tonight in patchy ground fog, manly aft 9z.

Extended outlook... MainlyVFR conditions through the period with
the exception of possible MVFR ifr conditions due to low clouds
and fog each morning, mainly between 9z-12z.

Near term through Saturday ...

as of 300 pm Friday... Although N through ene winds this period
will not be strong, increasing SE swell from maria has prompted
a 'hazardous seas' advisory, effective from 6 am Saturday
through at least early next week, likely into mid-week, since
maria will slow down once offshore of the carolinas. 4-7 foot se
waves every 15 seconds will produce turbulence and standing
waves in area inlets during the outgoing tides, while increasing
the width of the surfzone of tumultuous breakers. No tstms are
expected through Saturday over the 0-20 nm waters. Onshore winds
can be expected Saturday with high pressure to the north and
maria east of the bahamas.

Short term Saturday night through Sunday night ...

as of 300 pm Friday... High pressure will extend down from the
great lakes this weekend as jose continues to spin in the north
atlantic and maria treks north from north of the
bahamas. A general northeasterly flow will increase heading
into Sunday up to 15 to 20 kts in the outer waters, but
otherwise winds will be in the 5 to 10 kt range. A very long
period swell up to 11 to 15 seconds will continue through the
weekend. An increasing northeast shorter period wind swell will
combine with this longer period swell to produce an increase in
seas from near 6 to 7 ft in outer waters Sat eve up to 10 to 12
ft Sun night into Monday. Expect shoaling and large breaking
waves along the length of frying pan shoals. A small craft
advisory for hazardous seas mainly due to long period swells
will continue through the period.

Long term Monday through Wednesday ...

as of 300 pm Friday... Long period southeasterly swells will be
ongoing Monday, ranging from as high as 8 to 10 feet every 15
seconds in the outer waters (15-20 nm). South of CAPE fear,
these are likely to decay to 4 to 6 feet as they approach the
coast, but north of CAPE fear, 6 to 8 footers will push in
closer. Based on the latest forecast track for maria, northerly
winds will peak Tuesday night into Wednesday, with 20 to 25
knots north of CAPE fear. South of CAPE fear, a 15 to 20 knot
range can be expected. Expect small craft advisory conditions
through the entire period.

Tides coastal flooding
As of 300 pm Friday... A coastal flood advisory may be needed
for downtown wilmington and the lower CAPE fear but confidence
is low because of the marginality. Therefor will allow a few
more observations to arrive through afternoon, take into account
departures before an issuance if any. If a coastal flood
advisory is issued, the flooding itself will remain very minor.

Ilm watches warnings advisories
Sc... High rip current risk from Saturday morning through Saturday
evening for scz054-056.

Nc... High rip current risk from Saturday morning through Saturday
evening for ncz106-108-110.

Marine... Small craft advisory for hazardous seas from 6 am Saturday to
6 am edt Tuesday for amz250-252-254-256.
