Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
156 AM PDT Sat Mar 24 2018

.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 an area of gale winds associated
with a low center W of the offshore waters. The low is expected
to track SE across the region over the next 24 hours while
gradually weakening. The most recent satellite picture from 0830Z
indicates the low is approximately 50 miles W of the Oregon
offshore waters. Buoy 46002 reported 14 ft at 08Z and this is
right in good agreement with the wave grids and right in line
with the latest ENP guidance. The 00Z global models remain in
very good agreement and show excellent consistency over the past
several days. Once the low dissipates inland and a weak cold
front crosses the Washington and Oregon waters a very stable
pattern will take shape. The typical ridge/trough combination
will develop as high pressure builds N and NE over the NW
offshore waters while a low pressure trough develops and
intensifies along the California coast. I will populate the wind
grids using the 30M GFS through 03Z Sun, in order to better
indicate the maximum winds associated with the low center. I will
transition to a 50/50 blend of the 10M/30M GFS from 06Z
throughout the remainder of the forecast period.

Seas...Both the ENP and WAM were initialized well at 00Z and
remain in very good agreement over the next 7 days. I will
continue to populate the wave grids using the ENP during the
upcoming week.
