.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 low pressure northwest 
of the pz5 waters will continue to move north tonight while 
weakening. A cold front will then approach the pz5 waters by 
Thursday then weaken Thursday night. Another front will then 
approach the pz5 waters by Friday night. Farther south, mainly 
light winds will continue across most of the pz6 waters through 
Tuesday night. By late Friday, northerly winds will increase to 
30 knots across central portions of the pz6 waters as high 
pressure builds west of the area. These conditions will then 
continue into Sunday before weakening. The latest runs of the gfs
and ecmwf look to be in reasonable agreement across the offshore
waters through Sunday. For wind grids will use the gfs winds
throughout. Current forecast looks reasonable and will carry no 
warnings across the offshore waters during the forecast period.

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