Marine Weather Discussion for N Atlantic Ocean
NWS Ocean Prediction Center Washington DC
338 AM EDT Fri Jun 23 2017

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

Summary...The 00z ncep surface analysis shows a warm front
extending roughly se to nw across the nrn nt2 and srn nt1 waters,
with high pres ridges over most of the nt1 waters and across the
srn and central nt2 waters. Latest available ascat hi-res and
ascat passes from a few hours ago indicate 5 to 15 kt winds over
the offshore waters.

Models...00z medium range models are in good overall agreement
across the offshore waters through the forecast period, although
there are some minor timing differences evident for Tue and Tue
Night. However, the 00z gfs 10m solution has good support from
the latest wpc medium range forecaster guidance and appears to be
representative enough to be used for the wind grids over the
entire forecast period.

Seas...The 00z wna wavewatch and 00z ecmwf wam both initialized
reasonably well over the coastal/offshore waters. The models are
in good overall agreement across the offshore waters over the
entire forecast period, with only minor differences noted. A
representative 50/50 blend of the 00z wna wavewatch/ecmwf wam
will be used for the sea height grids for the entire forecast
period, in order to smooth out the model differences.

.Extratropical Storm Surge Guidance...N/A.

.WARNINGS...Preliminary.

.NT1 New England Waters...
     None.

.NT2 Mid-Atlantic Waters...
     None.
