Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1203 PM PST SAT JAN 21 2017

.FORECAST DISCUSSION...Major features/winds/seas/significant
.weather for the North Pacific N of 30N and E of 150W.

12Z model agreement has improved throughout the forecast period.
All models indicate a strong low moving through the central waters
tonight and tomorrow. Chose to cap the winds just below hurricane
force in keeping with the weaker ECMWF and UKMET...but gusts will
reach to hurricane force. The low will weaken and turn southeast
Mon and Monday night...winds will weaken as the low moves south
along the coast before dissipated on Wednesday.

The offshore waters will finally quiet a bit as high pressure
builds in for Tueday night through Thursday, but this will be
short lived as a more progressive pattern begins again. Will use
the 30m GFS through 12Z Tuesday and then use the 10m GFS through
the rest of the forecast period.

.SEAS...Plan on using the WaveWatch III through 12Z Tuesday to
keep in the higher seas expected with the strong low. Will use a
50/50 WWIII/WAM blend for the rest of the forecast.
