Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
206 AM PDT Sat Jun 24 2017

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

Altimeter passes from 03Z and 06Z indicate seas to 9 ft across
the offshore waters, with maximum waves over the northern and
central California area. The ASCAT pass from 06Z continues to
show a weakening pressure gradient across the Oregon and northern
California waters, with maximum winds to 25 kt. A weak low
center has formed West of the California waters near 33N 132W.
The 00Z global models continue to be in amazing agreement during
the upcoming week. The overall pattern will become weak as the NE
gradient continues its weakening trend, while a high pressure
ridge across the NW PZ5 waters weakens as well. The low center
west of the California waters will gradually weaken over the next
several days. Once that occurs a NW flow will take hold across
the entire region as strong high pressure begins to build W of
the area. Late in the week the winds along the California coast
will intensify to 30 kt, with 35 kt possible in the coastal zones
as the California trough begins to strengthen. I will populate
the wind grids using the 10M GFS throughout the period.

Seas...both the ENP and WAM are in good agreement for the next 7
days and were initialized well. I will populate the wave grids
using the ENP throughout the forecast period.

Extratropical Storm Surge Guidance: n/a.

.WARNINGS...Preliminary.

.PZ5 Washington/Oregon Waters...
     None.

.PZ6 California Waters...
     None.
