Marine Weather for HS 102


marine weather discussion for N Pacific Ocean NWS ocean prediction center Washington DC 113 PM PDT Tue Mar 19 2019

.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 cold front currently approaching the pz6 waters will move across the waters today through Wednesday. Another cold front will then move into the pz5 and northern pz6 waters by Friday. The strongest winds will be in the southerly flow ahead of the front with winds as high as 30 knots. Some minimal gale conditions are possible, but for now will keep the strongest winds over the offshore waters at 30 knots and see what the later model runs show. Yet another low and associated cold front will approach the pz6 waters by Sunday. The latest runs of the GFS and ECMWF look to be in reasonable agreement across the eastern Pacific through Sunday.

By Monday the GFS swings low pressure northward to a position just west of the Oregon offshore waters while the ECMWF is not really showing this system. Most of the other guidance is in better agreement with the GFS so at this time will favor the GFS across the offshore waters after Sunday. For wind grids will use the GFS winds throughout. Current forecast looks reasonable and will continue to carry no warnings across the offshore waters during the forecast period.

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

Extratropical storm surge guidance...N/A.


.Pz5 Washington/Oregon waters... None.

.Pz6 California waters... None.
