Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1218 PM PST FRI DEC 2 2016

.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 the low pressure trof
along the California coast continues to combine with a high
pressure ridge west of the pz6 waters to produce north to
northwest winds up to 30 knots off the coast of central and
southern California with the strongest conditions west of Point
Reyes. Conditions will slowly diminish through Saturday. Farther front will move through the pz5 waters today followed
by another front Saturday night. Low pressure will then move
southeast towards the Washington coast by late Monday. The latest
runs of the gfs and ecmwf look to be in reasonable agreement
through early Tuesday. By Tuesday and Wednesday the gfs is faster
than the ecmwf with the front forecast to move towards the pz5
waters. At this time will lean more towards the slower ecmwf
solution as it is supported by the ukmet. For wind grids will use
the gfs 10m winds through 96 hours...then transition to the ecmwf
winds. Current warnings look reasonable and few changes should be
needed on the next offshore waters forecast.

For wave grids will also use the ww3 through 96 hours...then
transition to the ecmwf wam after 96 hours.

Extratropical storm surge guidance...n/a.
