Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
157 AM PDT Wed May 24 2017

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

The ASCAT pass from 06Z shows mainly 20-30 kt stretching from
the northern portion of the central California waters through the
PZ5 waters. A small area of gales are located along the boundary
of the Oregon and California region, across the far inner waters.
Further S, light winds associated with a trough axis are
indicated across the central California waters. A NW flow will
persist across the offshore waters during the upcoming week.
Strong High pressure W of the offshore waters coupled with a
trough along the Northern California coast will produce gale
conditions over the inner offshore waters along the northern
California coast. Another trough across Vancouver island will
also help to increase the winds briefly to gale across the NE
portion of the Washington waters. After 24 hours or so the ridge
to the west of the area will begin to weaken and winds will
diminish across the offshore waters. The weak gradient will
persist for the remainder of the week producing light wind over
the area. The 00Z global models are all in pretty good agreement
over the region with only minor differences indicated. I will
populate the wind grids using a 50/50 blend of the 10M and 30M
GFS throughout the forecast period.

seas...Both the ENP and WAM initialized well across the region
with only slight differences indicated during the forecast
period. I will populate the wave grids using the ENP throughout
the week.
