Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
654 AM PST Wed Dec 13 2017

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

Model guidance is in fairly good agreement throughout the
forecast period. Will make some edits, but nothing significant.
Will keep the gales in indicated by previous forecast.

-----------------------------------------------------------------
PREVIOUS DISCUSSION...

The latest model guidance indicates that a high pressure ridge 
is currently causing mainly light winds across most of the 
offshore waters. A weak cold front will move into the pz5 waters 
by Thursday, then dissipate Thursday night. Another front will 
then move into the pz5 waters by Saturday. Farther south, 
northerly winds will increase to 30 knots off of northern 
California by late Friday as strong high pressure builds west of 
the offshore waters. Minimal gales are then expected from late
Saturday into Sunday across portions of the northern pz6 waters. 
These conditions will then diminish somewhat by late Sunday. The
latest runs of the gfs and ecmwf look to be in reasonable 
agreement across the eastern Pacific through Sunday. For wind 
grids will use the gfs winds throughout. Only change to warnings
will be to add minimal gales across portions of the northern pz6
waters late Saturday into Sunday.

For wave height grids will also continue to use the ww3
throughout the forecast period.

Extratropical storm surge guidance...n/a.



.WARNINGS...Preliminary.

.PZ5 Washington/Oregon Waters...
     None.

.PZ6 California Waters...
.PZZ820...Inner Waters from Point St. George to Point Arena...
     Gale Possible Saturday into Sunday.
