Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1223 AM PST Mon Dec 11 2017

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

The latest model guidance indicates that a cold front currently 
approaching the pz5 and northern pz6 waters will move across the 
northern pz5 waters by late Monday and Monday night. Still expect
minimal gales across the far northwest Washington offshore 
waters by Monday night in association with low pressure along the
front. Another weakening cold front will then approach the pz5 
waters by Wednesday night, then move into the offshore waters by 
Thursday and Thursday night. Farther south, mainly light winds 
will continue across most of the southern and central pz6 waters 
through Tuesday night, then begin to strengthen a bit. Northerly 
winds will then increase to near gale force by late Friday as 
strong high pressure builds west of the offshore waters. The
latest runs of the gfs and ecmwf look to be in reasonable
agreement across the offshore waters through Thursday.

By Friday the gfs moves low pressure north of the pz5 waters 
while the ukmet and ecmwf do not have this system. At this time 
will favor the ecmwf/ukmet solution across the offshore waters by
Friday. For wind grids will use the gfs winds through Thursday, 
then transition to the ecmwf winds. 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 Thursday,
then transition to the ecmwf wam.

Extratropical storm surge guidance...n/a. 


.WARNINGS...Preliminary.

.PZ5 Washington/Oregon Waters...
.PZZ900...Outer Waters from Cape Flattery to Cape Shoalwater...
     Gale tonight.

     None.
