Synopsis
High pressure will prevail across the mid atlantic through
Tuesday. Meanwhile, maria will continue to track north well off
the coast while gradually weakening. Maria lingers off the outer
banks Wednesday, before pushing farther offshore Thursday ahead
of an approaching cold front late in the week.

Near term until 6 am Tuesday morning
High pressure remains anchored over the ERN great lakes and
northeast CONUS this afternoon. Hurricane maria (presently a
category 1) is situated ~300mi sse of CAPE hatteras. There are
varying amounts of cloud cover over the area this afternoon with
mostly sunny conditions north west... And low stratus stratocu
cover immediate coastal locations into SE va NE nc. There's no
pcpn to speak of at the moment as outermost bands from maria
remain off the outer banks. Based on current trends will hold
off on introducing low pops until after 00z across the
southeast. Increased low-level moisture along the immediate
coast this afternoon will quickly spread inland this evening
with overcast conditions becoming prominent most areas
overnight. Lows temps will range from the mid 60s inland to the
low 70s along the immediate coast.

Short term 6 am Tuesday morning through Thursday
Maria continues to push N Tuesday, and perhaps slightly W of
due N as an upper low drops sewd across fl. Increasing moisture
and some outer banded features will result in 20-35% pops along
and E of i-95 Tuesday. QPF will be minimal for most areas. Highs
in the upper 70s to low 80s Tuesday under a mostly cloudy sky.

Becoming breezy along the coast with a NE wind increasing to
15-25 mph, with gusts up to 30-35 mph possible.

Maria reaches about 160mi ese of CAPE hatteras by 00z
Wednesday, around 150mi E of CAPE hatteras by 12z Wednesday, and
then 140-180mi ene of CAPE hatteras by 00z Thursday as some
spread remains in the guidance. NHC has maria weakening to a
tropical storm during this time-frame. The offshore track will
result in minimal rainfall across SE va NE nc (and coastal md to
a lesser degree), generally 0.50" or less. There is still a
potential for modestly strong wind gusts south of CAPE charles
on the coastal waters, and along the immediate coast from orf va
beach to the currituck county beaches (including the currituck
sound). Tropical storm watches for these areas are currently in
effect which may be upgraded to warnings later this afternoon.

High seas and minor or localized moderate coastal flooding will
also occur along the coast. Will have pops of 20-40% east of
i-95 Wed (40-50% coastal NE nc Tue night), with slight chc pops
into the piedmont. Wind gusts could reach 30-45 mph from around
norfolk va beach southward into coastal NE nc. The biggest
impacts will likely be from tidal flooding and beach erosion
along near the coast. Highs Wed from the upr 70s coast to the
low mid 80s inland, after morning lows in the 60s and low 70s.

By 12z thu, maria is shown to move NE to around 200-260 miles
ene of CAPE hatteras, then pushing well offshore by late in the
day. Will carry lingering slight chc pops (~20%) along the
coast for primarily the morning hours. Otherwise, decreasing
clouds through the day. Highs from the upr 70 coast to low mid
80s inland.

Long term Thursday night through Monday
Very quiet weather expected in the extended as a positively tilted
upper trough swings across the great lakes and northeastern us
Friday and Saturday. This trough will serve to escort maria away
from the coast and at the same time push a weak cold front through
the region on Thursday night. This will allow drier and cooler air
to move back into the region. Expect overnight lows in the mid to
upper 50s thurs and Friday night with highs Friday in the mid 70s. A
secondary area of low pressure and a reinforcing cold front will
slide through the area on Saturday as the upper trough pivots off
the coast on Saturday. But moisture will be limited with the front
and the best chance for any showers will be over the delmarva. By
Sunday, a strong area of high pressure is building across new
england and down the eastern seaboard on Sunday and Monday. This
will provide dry and seasonable temperatures with highs in the
low. To mid 70s and overnight lows in the low to mid 50s.

Aviation 19z Monday through Saturday
MVFR to local ifr conditions are prominent along the immediate
coast and portions of SE va NE nc this afternoon. Elsewhere,VFR
conditions prevail with a clear mainly clear sky. MVFR cigs
will gradually push farther inland this evening, reaching kric
around 03z, and potentially falling to ifr overnight at all taf
sites. A NE wind of 10-15kt along the immediate coast this
afternoon tonight will increase to 15-20kt with gusts around 25
kt Tuesday morning.

Outlook: increasing moisture from maria will result in a 20-40%
chc for showers Tuesday Wednesday. Locally stronger wind
speeds gusts are expected at orf ecg Tuesday night Wednesday. A
cold front approaches from the NW Thursday Friday and pushes
maria farther offshore with conditions improving
Thursday Friday.

Marine
Hurricane maria is located about 380 miles sse of CAPE hatteras
nc as of 500 am. Meanwhile, high pressure remains centered
north of the area. The hurricane is forecast to track northward
well off the SE coast today into this evening, then moves to
well east of the nc outer banks by early Wed morning. The storm
will then start to track northeast Wed aftn and evening, then
accelerate ene out to sea late Wed night into Thu night. Ne
winds and waves seas will start to increase build over the
waters, esply SRN waters, this evening into Tue morning, as the
storm moves northward to well off the SE nc coast. NE winds will
increase to 10 to 20 kt with gusts to 25-30 kt by Tue morning,
with waves building to 2-5 ft (near 6 ft mouth of the bay), and
seas building to 6-10 ft.

Strongest NE winds and highest waves and seas will affect the
waters Tue night into Wed night with gusts to 35-45 kt a good
bet over the SRN ches bay, currituck sound, and va nc coastal
waters. A tropical storm watch remains in effect for the currituck
sound, and SRN waters from the va nc border to currituck beach
light until 12z 800 am Thu morning. Aforementioned areas above
may be added to the watch this aftn, since impacts farther
north of the watch area are not anticipated to begin until tue
evening. Elsewhere, strong solid SCA conditions (20-30kt) will
occur. Seas will build as high as 14-15 ft south and 10-14 ft
north. N winds will then diminish west to east late Wed night
thru thu.

Please monitor the NHC forecast for the official forecast
track of hurricane maria.

Tides coastal flooding
Minor to possibly moderate tidal flooding could occur at many
sites in the middle to lower bay, and SRN va and NE nc coastal
waters Wed into Thu morning. High surf advisories have been
issued for tue, and lasting into wed. The combination of storm
surge and large waves could result in some coastal erosion and
damage to dune structures later Tue into Wed night.

High risk for rip currents for all beaches adjacent to coastal
waters continues through today, as 4-5 ft nearshore waves and
13-15 second swell persists.

Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
