Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1232 AM PST Mon Nov 20 2017

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

The latest model runs are indicating that the cold front 
currently across the pz5 waters will move inland later tonight 
and early Mon. Still expect gale force winds up to 40 kt tonight 
across portions of the pz5 waters ahead of the front. Another low
will then track west of the pz5 waters Mon night and Tue with 
more gales expected for the pz5 and northern pz6 waters. Yet 
another low is then expected to track west of the pz5 waters Wed 
and Wed night. Farther south, mainly light winds are expected 
across most of the southern pz6 waters Mon into Thu. The latest
runs of the gfs and ecmwf look to be in reasonable agreement
across the eastern Pacific through early Sat. By Sat the gfs
moves low pressure across the northern pz6 waters while the ecmwf
is weaker with the system. At this time will lean towards the
ecmwf with this system as it is supported by the ukmet. For wind
grids will use the gfs winds through early Sat, then transition
to the ecmwf. Current warnings look reasonable and few changes 
should be needed on the next offshore waters forecast.

For wave height grids will also use the ww3 through early Sat,
then transition to the ecmwf wam.
