Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
138 AM PDT Wed Jun 28 2017

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

The 00Z model agreement continues to be good throughout the
forecast period. Will use the 10m GFS with some edits throughout
to adjust for minor differences in model solutions. Very little
will change with this forecast as models have been consistent
from run to run.

High pressure building to the west and a strong coastal trough
will continue to be the greatest impact of the forecast period.
Not expecting to see gales in the offshore waters; however, gales
are possible in the coastal areas late in the forecast.

Tropical Storm Dora remains to the south of the forecast waters
near 19.8N 113.1W at 09Z. It is expected to move west-northwest
while weakening. It will have no significant impact on the
offshore waters.

.SEAS...Wavewatch initialized only slightly better than the WAM
so will use the Wavewatch. Will need to decrease the seas late in
the period as the Wavewatch appears to be too high. Will edit
those grids toward the ECMWF WAM.



.PZ5 Washington/Oregon Waters...

.PZ6 California Waters...
