Marine Weather for HS 102


marine weather discussion for N Pacific Ocean NWS ocean prediction center Washington DC 104 PM PDT Tue Aug 21 2018

.Forecast discussion...Major features/winds/seas/significant .Weather for the North Pacific N of 30n and E of 150w.

A high pressure ridge west of the offshore waters is currently combining with a low pressure trof near the coast to produce north to northwest winds up to 20 knots across portions of the pz5 and northern pz6 waters. By late Wednesday northwest winds will increase to 30 knots across the northeast portion of the Washington offshore waters as the high west of the pz5 waters strengthens. Winds will then remain near 30 knots across the northeast Washington waters into Thursday night. By late Friday the strongest winds will shift south to a position off of northern California with winds up to 30 knots. These conditions will then continue to the end of the forecast period. 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 10m 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 continue to use the nww3 throughout the forecast period.

Extratropical storm surge guidance...N/A.


.Pz5 Washington/Oregon waters... None.

.Pz6 California waters... None.
