Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
113 AM PST Mon Feb 19 2018

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

The ASCAT pass from 05Z shows winds to 40 kt across much of the
offshore waters N of Point Arena, while an altimeter pass from
03Z indicates seas to 27 ft in the Oregon waters. The overall
forecast pattern hasn`t changed much over the past several days.
The main driving forces controlling the conditions across the
offshore waters will continue being a stable ridge axis W of the
waters in combination with a low pressure trough along the
California waters. Occasional short waves digging SE across the
region will occasionally disrupt the flow and weaken the trough.
the 00Z global models remain in very good agreement throughout
the forecast period and in order to maintain continuity I will
populate the wind grids using the 10/30M GFS throughout the
forecast period.

Seas...Both the ENP and WAM initialized well and match up with
the current grids. I don`t see a need to make many radical
changes to the previous forecast and will populate the wave grids
using the ENP during the entire week.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A.
