Synopsis
High pressure will extend into the area through Monday.

Hurricane maria is expected to track slowly off the east coast
early to mid next week. A cold front will cross the area late next
week. Please see the latest official forecasts from the national
hurricane center and local NWS offices.

Near term until 6 pm this evening
As of 250 am Sunday... A 1020 mb high over the northeast third of
the country will remain in control of our weather today. Highs
will be well into the 80s or just about the same as Saturday.

We will see periods of high clouds from time to time moving in
from maria. They will be thickest toward the coastal waters. The
pressure gradient between the high to our north and maria will
also be stronger today. This will lead to breezier conditions
which will be most pronounced along the coast, especially the
outer banks where gusts above 20 mph will be common.

Short term 6 pm this evening through 6 am Monday
As of 250 am Sunday...

as high pressure begins to retreat and maria moves northward
tonight, a continued onshore flow will increase cloud cover
especially along the coast. The bulk of the showers will remain
over the coastal waters but an isolated shower is possible along
the outer banks late. It will remain breezy especially along
the coast. While winds drop off inland it should be enough to
prevent fog formation.

Long term Monday through Saturday
As of 315 pm Saturday... The big player in the forecast for the week
ahead will be hurricane maria tracking off the coast. There remains
high uncertainty with the exact track of the storm, but there has
been an increasing chance that there will be some significant
impacts along the coast. Eastern nc residents and interested parties
should continue to monitor the latest official forecasts from nhc.

Sunday night through Monday night... Surface high pressure and upper
ridge will continue to build in from the north early next week, as
the remnants of jose weakens well off the NE coast. Expect Sunday
night to be predominately dry, but could see some showers pushing
onshore as early as Monday as maria lifts north off the southeast
coast. Expect slightly above normal temps with highs in the mid 80s
inland to upper 70s along the coast. Monday night lows expected in
the upper 60s coastal plain to low to mid 70s along the coast.

Tuesday through Friday... Hurricane maria is currently forecast
to slowly lift north off the SE coast through mid week. Eventual
track will be determined by several factors including the
strength of the upper ridge and the timing of a shortwave trough
and attendant cold front expected to push across the mid-
atlantic states mid to late week. It is still too soon to
determine specific impacts for eastern nc, which will be very
dependent on the track how close to the coast it gets. There is some
fair amount of spread in the models, but some, like the GFS bring a
strong maria closer to the coast. Regardless of the exact track,
rough surf and dangerous rip currents are likely through much of
next week, as large long period southeast swells build.

At a minimum, coastal areas can expect gusty N NW winds close to
tropical storm force, minor coastal flooding, and ocean
overwash erosion will be also possible, with the greatest threat
along the outer banks. At this point can't rule out more impactful
coastal flooding for the southern pamlico sound and sound side of
the outer banks and ocracoke. Residents in low lying vulnerable
areas should closely monitor the forecast.

Continue slight chance to chance pops through mid week, highest
eastern sections. The next frontal system will approach the area
late week aiding to maria pushes further ene offshore.

Temps through the period, near to slightly above normal with
highs in the 80s and lows in the mid 60s low 70s.

Aviation 07z Sunday through Thursday
Short term through tonight ...

as of 150 am pm Saturday... MainlyVFR as a very light NE wind
and high clouds shld limit fog threat to deep inland. Felt best
risk for brief ifr would be at kpgv otherwise wind and clouds
should be enough to prevent widespread fog formation. Any fog
and low clouds shld dissipate in the morn withVFR rest of the
day.VFR expected tonight.

Long term Sunday night through Thursday ...

as of 315 pm Saturday...VFR conditions will dominate through
mon, though some early morning fg br and low stratus may develop
each night as a ridge of high pres will be across the region.

Periods of sub-vfr poss Tue into Thu with isold to sct showers
pushing onshore as maria lifts toward the region.

Marine
Short term through Sunday ...

as of 250 am Sunday... Building seas and increasing winds will
lead to deteriorating conditions over the coastal waters today
and tonight.

Seas are still running 5 to 7 feet over the coastal waters, as
northeast winds have increased to 15 to 20 kts. Seas build to 7
to 12 feet late today and 8 to 15 feet tonight. Northeast winds
will increase to 20 to 30 kts from later today through tonight.

Long term Sunday night through Thursday ...

as of 315 pm Saturday... High pres centered over the great lakes
will build down into the SE through the period, while hurricane
maria lifts N off the SE coast. Increasing uncertainty conts
regarding the track of maria as it approaches the region as
latest model guidance conts a westward trend closer the the nc
coast as well as conts to slow it down. Mariners and interested
parties should cont to monitor the latest official forecasts
from nhc. SCA cont for all coastal waters thru the period.

Based on the latest forecast, N NE winds increase to 15-25 kt
Sunday night thru Tue as maria lifts northward, increasing to
25 to 30 kt on the cusp of trop storm force Tue night thru wed.

The GFS showed significantly stronger winds, but did not buy
off on that at this time. Winds will begin to decrease slowly as
maria pulls away from the coast Wed night into thu. There will
be a long period of very dangerous boating conditions tue
through wed, with seas peaking close to 20 ft in our coastal
waters, and could be possibly higher depending on how maria
behaves.

Dangerous high surf, at least minor overwash, and dangerous rip
currents are almost a certainty.
