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.
