Synopsis
Hazardous beach conditions will continue for much of the week.

Large hurricane maria will continue to move slowly to the
north, with its center passing about 300 miles offshore of the
cape fear coast through Wednesday. A cold front will move across
the area late Thursday with high pressure and cooler temperatures
building into the area beginning Friday.

Near term through Tuesday
As of 300 pm Monday... Conditions will change very little during
the near term period. The slow movement of hurricane maria will
continue to bring mostly to partly cloudy skies with breezy
conditions and little chance for rain. There will be more cloud
cover along coastal areas with closer proximity to the lumbering
storm. I adjusted tonight's overnight lows up a degree or two
based on a mixed boundary layer. The clouds have certainly held
today's highs in check and with similar conditions expected
Tuesday, I walked back highs considerably.

Short term Tuesday night through Wednesday night
As of 300 pm Monday... Hurricane maria will likely weaken into a
tropical storm through mid-week as she moves north along and
east of the nc coast. Maria will be distant enough to prevent
any significant impacts locally although gusty north winds are
likely Tuesday night through Wednesday, along with periods of
clouds. However, beginning the latter half of Wednesday the cwa
will be within the subsident region around maria, noted by
drying and subsidence in time-heights, creating abnormally warm
temperatures and decreasing cloudiness the second half of the
short term. A few isolated showers are possible along the cape
fear coast Tuesday night, but this will end by Wednesday with no
further precip forecast thanks to most of the moisture
remaining offshore. As winds begin to ease late Wednesday, there
will be very little indication locally that a tropical storm is
in the vicinity unless you are at the beaches to see the waves.

Increasing sunshine and subsidence will drive temps to near 90
Wednesday, just short of record highs for the date, with mins
both nights above 70, more than 10 degrees above normal for late
september.

Long term Thursday through Monday
As of 300 pm Monday... Subsidence in the wake of maria and pre-
frontal warming will lead to one more day of above-average
temperatures before a cooling trend commences. A consensus of
guidance gives us highs of around 90 on Thursday. A cold front
will move offshore later on Thursday, bringing us near to well-
below normal temperatures by Friday, with cool weather
continuing into the weekend. The cold front will come through
dry, although isolated to widely scattered showers are possible
along the coast Friday night into Saturday as a strong upper
disturbance dips SE across the mid-atlantic states.

Aviation 00z Tuesday through Saturday
As of 00z... Expect ceilings to lower at the coastal terminals,
bottoming out with low end MVFR or high end ifr after 08z or so.

Then ceilings will lift toVFR at kcre and kmyr Tue afternoon
with perhaps MVFR ceilings hanging on through the end of the
period at kilm. At kflo and klbt, the moisture will not be as
deep and the western periphery of low clouds associated with
hurricane maria are not expected to extend that far inland. Will
maintainVFR forecast at kflo. Will forecast MVFR at klbt from
about 07z-17z, although confidence is low, and then forecast
vfr for the remainder of the period here. Since the risk for
showers will be so low, even at the coast, did not include in
any of the tafs. Winds at the coastal terminals may gust to 18
to 22 kt with the more persistent gusts confined to kilm,
especially on tue.

Extended outlook... MVFR ceilings may linger redevelop at the
coastal terminals Tue night, mainly kilm. Wind gusts at kilm
may gust to 15 to 20 kt into wed.

Marine
Near term through Tuesday ...

as of 300 pm Monday... Rough and tumble conditions will continue
through the period for the coastal waters. Little change is
expected with north to northeast winds of 20-25 knots.

Significant seas will remain elevated as well. Will continue the
high surf advisory and the small craft advisory. The strongest
winds of the period will occur early Tuesday across amz 250
possibly just above the 20-25 knot range for a couple of hours.

Short term Tuesday night through Wednesday night ...

as of 300 pm Monday... Gusty N NW winds will slowly ease through
the period as hurricane maria moves slowly well east of the nc
coast. Winds Tuesday night will be N at 15-25 kts, highest
amz250, before slowly easing to 10-15 kts Wed night from the nw.

While these winds are mostly offshore and thus create only a
limited wind wave amplitude, large swell from maria at 4-5 ft 12
sec combined with the wind wave will create large seas and an
sca remains in effect through 8pm Wednesday evening. Wave
heights Tuesday night will be 6- 9 ft, with some 10 fters
possible in the far NE waters, before falling slowly through
Wednesday to 3-5 ft, and then 2-4 ft at the end of the period.

Long term Thursday through Saturday ...

as of 300 pm Monday... Expect gradually improving conditions
over the waters as maria moves well northeast into the central
atlantic and a weak pressure gradient takes its place. Do not
expect any warnings or advisories during the long term. Highest
winds and seas will be on Thursday for our nc coastal waters,
with 10 to 15 kt winds and 3 to 5 ft seas. These conditions will
improve, with seas in the 2 to 4 ft range and winds of only
around 10 kts throughout by evening.

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

Nc... High rip current risk through Tuesday evening for ncz106-108-
110.

Marine... Small craft advisory until 8 pm edt Wednesday for amz250-252-
254-256.
