Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
349 PM EST Mon Feb 18 2019

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

This morning's ASCAT passes confirmed the presence of SW gales
along the cold front associated with developing low pressure 
crossing the far northern NT2 waters, mainly along and S of the
Gulf Stream in ANZ910 and 920 and also increasing winds behind
the cold front. The low itself about to pass east of the 
northern NT2 waters as per 18Z surface analysis, with the cold 
front now crossing the southern NT2 waters. The latest surface 
observations and ASCAT are showing some winds stronger than 20 
kt west and N of the Gulf Stream, such as at buoy 44025 and in
Georges Bank with 25 kt. The synoptic pattern appears to be
consolidating as the offshore low rapidly deepens E of the area
and low pressure weakens near New England. The 12Z models were 
still consistent that the departing low will produce a period of 
NW gale winds into early tonight and in fact GFS and high 
resolution guidance such as ARW and NMM support briefly 
extending NW gales into southern NT1 zone such as ANZ815. We 
continue to have well above average confidence with the gale 
warnings in the moderate cold air advection in the wake of the 
cold front and low tonight. We populated near term grids through 
00Z Wed with the 12Z GFS first sigma level winds except blended 
in the 12Z WRF-ARW for tonight. The cold front will stall later 
tonight just south of the area, with high pressure ridge 
building into the area early Tue and persisting early Wed. The 
aforementioned departing low is expected to rapidly deepen into 
a hurricane-force low as it tracks about 350 to 400 nm southeast 
of Cape Race Newfoundland Tue morning. The models are also 
consistent in developing a coastal front from near Cape Hatteras 
southward to the Georgia coast Tue night into Wed. We used the 
12Z WRF/ARW Tue night and early Wed which shows the coastal 
front best. 

Then for Wed and beyond, another low will develop near the SE 
coast early Wed, likely along the coastal front, then move 
northeast along the coast while lifting a warm front north. The 
12Z models then remained relatively consistent with this coastal 
low development Wed into Thu, which will likely result in more 
gale force winds developing at least again across the northern 
outer NT2 zones Thu into Thu evening. The latest GFS has 
departed a bit N of the model consensus by Thu and showing a 
less defined coastal low while the ECMWF/CMC/UKMET are well 
clustered. Starting Wed favored the 12Z ECMWF and boosted its 
winds by 10 percent along the Gulf Stream and then later Thu and 
Thu night throughout in NW flow and cold advection. Made no 
changes after Thu night using the previous grids which match up 
with the new WPC medium range guidance. The next low pressure 
arrives beyond day 5.

.Seas: The 12Z Wavewatch and 12Z ECMWF WAM were equally well 
initialized with the coastal and offshore wave heights at 18Z. 
However as the cold advection increases into tonight we will 
favor the somewhat higher 12Z WAM for the wave heights through 
Thu night also reflecting choice of 12Z ECMWF for winds. After 
Thu night used the previous grids as was done for winds.

.EXTRATROPICAL STORM SURGE GUIDANCE...No significant positive 
storm surge events are expected through tonight. As was noted 
above with the coastal front setting up off the Georgia and 
Carolina coasts, and generating some enhanced east to northeast 
winds, there is potential for some minor to potentially moderate 
surge from Charleston to northeast Florida. The ESTOFS is once 
again showing values around 1 to 1.5 ft Tue night, with the ETSS 
1 ft and below. For more details please monitor the latest 
forecast and information from your local National Weather 
Service office.

.SYNOPSIS FOR NEW ENGLAND WATERS...Low pressure will rapidly
intensify as it passes E of the southern waters by early 
tonight. A strong high pressure ridge will build SE over the 
region late tonight and persist into Wed night. Another 
developing low will approach the waters from the SW late Wed 
night, then move E across the area Thu. High pressure will slowly
build E toward the coast Thu night into early Sat, then pass E of
the area later Sat and Sat night.
