Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
1222 PM PST SAT DEC 3 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 a low pressure trof
along the California coast continues to combine with a high
pressure ridge centered west of the pz6 waters to produce
northerly winds up to 25 knots off the coast of central and
southern California with the strongest conditions west of Pigeon
Point. Conditions will slowly diminish today and tonight and then
begin to increase again by Sunday and Sunday night. Farther
north...a cold front is still expected to move southeast across
the pz5 waters Saturday night followed by low pressure dropping
southeast by Monday. The models have been fairly consistent the
past few runs in showing minimal gales across the western pz5
waters by late Mon...so will go ahead and add them on the next
forecast. The latest runs of the gfs and ecmwf look to be in
reasonable agreement across the eastern Pacific through late
Tuesday.

Another cold front will then move into the pz5 waters by
Wednesday night with gale conditions possible. The latest run of
the gfs continues to be faster with the front than the ecmwf...but
at this time will continue to favor the slower ecmwf solution. For
wind grids will use the gfs 10m winds through late Tuesday...then
transition to the ecmwf winds through late Thursday. Only change
to warnings will be to add gales to the western pz5 waters by late
Monday and Monday night.

For wave grids will also use the ww3 through late Tuesday...then
transition to the ecmwf wam through late Thursday.

Extratropical storm surge guidance...n/a.
