Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
908 PM EST Sun Dec 9 2018

.FORECAST DISCUSSION...Major features/winds/seas/significant 
.weather for the North Atlantic Ocean W of 50W from 30N to 50N.

The latest NCEP surface analysis and current surface observations
show a developing low pressure system across the NT2 offshore
waters this evening, and the cyclonic turning in the winds along
the coast indicates the low center just offshore between Cape
Hatteras and Cape Lookout. The analysis also indicates that the
pressure gradient has tightened between the strengthening low and
a high pressure ridge to the NE, with strong easterly flow over
the Gulf Stream across central and northern NT2. The current
reports indicate winds up to 35 kt to the E and N of the low,
though none are in the vicinity of where the 18Z GFS and 12Z
ECMWF showed the highest winds which are indicated in zones to
the W of the nrn Outer Banks. The previous forecast had storm
force winds over several of the central NT2 offshore zones, and
this seems reasonable when considering the deep mixing indicated
by the convective activity in the GOES infrared satellite imagery
and the lightning density product which shows the front acting 
as a focus for convection mainly in the unstable environment over
the Gulf Stream. Confidence remains high on the storm force 
headlines as a result of the strong satellite signature, and very
high with the large area of surrounding gales which covers a 
large portion of NT2. The models are in fairly good agreement on 
the track and intensity of the low, and all indicate a second low
will form and move quickly off the E tonight and Mon in response
to a quickly moving shortwave trough passing through area 
coincident with the right entrance region of a strong upper level
jet streak moving quickly to the E. The models then indicate the
initial low moving slowly E across central NT2 as another 
shortwaves slides offshore, then shows the low passing E of the 
offshore waters by Tue night. The GFS is slightly faster than the
bulk of the 12Z guidance, and as such was determined to be too 
fast. The previous forecast opted for a slower solution most 
similar to the ECMWF, while boosting winds in the vicinity of the
Gulf Stream to account for its low wind bias. This keeps gales 
in the NT2 waters into Tue, before a small area of storm force 
winds redevelop near the low in the outer waters over the Gulf 
Stream. This again coincides with the right entrance region of a 
secondary jet streak, and also with a potent shortwave moving 
offshore to help the mixing with forcing some development. Since 
the 18Z GFS continues to run a little faster than the rest of the
guidance, am planning on staying near the slower ECMWF solution 
until the low eventually passes off to the E on Tue night. Will 
only be making minor edits to the previous grids to incorporate 
current conditions.

The models then remain in fairly good agreement Wed with a ridge
moving across the waters, before a weaker shortwave tough moves
across the nrn zones late Thu. There are some differences on the
trough, with the GFS a weak outlier when compared with the rest
of the guidance. The models then indicate a stronger system
approaching the coast from the W on Fri, and there is a fair
amount of model spread in the 12Z and 18Z guidance. The 12Z ECMWF
trended faster from its previous run, and is now a fast outlier
when compared with the rest of the models. There are also tack
differences, with the GFS/GEM taking a more northerly track from
the UKMET and ECMWF. The 18Z GEFS do not show a strong signal for
any particular solution, so at this point am planning on staying
near continuity as would prefer to see a stronger trend in the
guidance before making any major changes in the medium range
period.

-----------------------------------------------------------------
PREVIOUS DISCUSSION...

Over the short term, ASCAT overpasses from this morning indicated 
widespread gales occurring from near Hatteras Canyon south and
southwestward over the central and southern NT2 offshore waters.
These winds aligned quite well with the ongoing OPC forecast. Low
pressure located about 60 NM S of Charleston, S.C. according to
the 18Z preliminary OPC-NCEP surface analysis will move NE
tonight with storm force winds likely developing within the next
3-6 hours especially near the west wall of the gulf stream E and
NE of Cape Hatteras. As the low tracks further NE overnight the
stronger winds will shift E with a second low forming E of Cape
Fear, N.C. early Mon. This low will track generally eastward Mon
into Mon night, before turning NE and intensifying as it moves
away from the offshore waters Tue into Tue night. Another area of
storm force winds will likely develop with this second low as it
pulls E and NE away from the area Tue. Slowly improving
conditions can be expected Tue night as this low moves further NE
away from the waters with some potential for hurricane force
winds at that time, well E of the offshore waters. Forecast
confidence levels are above average for gales over portions of
the waters into Tue, and near average for storm force winds over
the zones indicated below. Scattered strong thunderstorms may
also accompany each low pressure area and associated frontal
boundaries as the cross the region tonight into Tue. Currently
the latest GOES-visible imagery and lightning density data show a
few scattered thunderstorms off the Georgia and Carolina coasts
moving generally toward the NE. Caution is advised for very gusty
winds and very rough seas in and near any of the heavier 
thunderstorms that cross mainly southern and central NT2 
offshore waters over the next 24-48 hours, with winds exceeding 
gale force likely. For the late afternoon package, we will remain
close to the previous grids into Mon, then transition more toward
the consistent 12Z ECMWF guidance later Mon into Tue night over
the waters and use the smart tool which will boost the ECMWF
winds up to 15 percent or so over and E of the gulf stream. The
ECMWF remains just about in the middle of the guidance envelope
into Tue night over the waters, with the 12Z GFS appearing to be
a little too far N with the second low as described above.

Over the medium range, we will continue to populate grids with
the 12Z ECMWF winds for Wed through Fri night over the waters,
and use the boost tool into Thu as noted above. For Fri night we
will boost winds 5-10 percent over the warmer waters of the 
southern and central NT2 waters, but cap winds at 40 kt, until
better model agreement develops over the next few days.
Intensifying low pressure will be moving NE away from the region
Wed as high pressure builds SE from eastern Canada. The high will
then build SE over the region later Wed night into Thu. The high
will begin to move SE from the New England waters Thu night as a
coastal trough or front forms just off the SE U.S. coast. The
high will then shift E of the region Fri into Fri night as low 
pressure moves from the SE states to the South and North 
Carolina coasts. As there remains a good deal of spread in the
12Z model guidance regarding both the location and the intensity
of the low impacting the waters Fri and Fri night we have decided
to cap winds as noted previously, but we feel confident enough
to add lower end gales to the offshore forecast for Fri night as
noted below. Additional adjustments to the hazards and forecast
are likely over the next few days. Please closely monitor the 
latest OPC forecast.

.Seas: For the afternoon package, we will blend in about 20
percent of the 12Z WAM wave guidance for tonight into Mon and
adjust grids to fit current conditions and nearby coastal WFO and
TAFB grids, with a continued boost of up to 10-15 percent in the
gulf stream into Mon night, with as noted previously, the wave
and current interactions within these counterflow scenarios over
the gulf stream will produce locally higher wave heights with an
locally enhanced steepening of the waves and a large gradient in
wave heights across short distances, all resulting in a 
dangerous sea state for the next 36 to 48 hours over the NT2 
waters. For Mon night into Fri night we will rely on the 12Z WAM
guidance with continued enhancements in the gulf stream to match
the wind forecast.

.Extratropical Storm Surge Guidance: As the onshore winds 
continue to increase and shift northward off the southeast US 
coast through tonight, surge should also steadily increase and 
shift N. Water level anomalies seem to be generally running 
about + 1,0-2.0 ft along the Georgia, South Carolina, and parts 
of the North Carolina early this afternoon. The 12Z ETSS, and to 
a somewhat lesser extent, the 12Z ESTOFS both still appear 
underdone at the moment and are likely too low through the near 
term. Interests along the mid-Atlantic and Southeast U.S. coasts 
should monitor the latest advisories or warnings, and forecasts 
from coastal National Weather Service offices.
