Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
702 PM PDT Wed Sep 19 2018

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

High pressure centered west of the pz6 waters continues to
combine with inland low pressure to produce northwest winds up to
30 knots across portions of the pz6 waters with the strongest
conditions west of Point Arena. Winds up to 30 knots will
continue across portions of the pz6 waters into Thursday night
and then begin to diminish. Winds up to 20 knots are still
possible west of Point Arena by early Saturday. Winds will
then increase again to minimal gales by Monday with the strongest
conditions west of Point St George. Farther north, low pressure
will move just north of the pz5 waters Friday and Friday night
with gale conditions associated with this low. The latest gfs is
now a bit farther north and slower with the low than some of its
previous runs. For wind grids will continue to use the current 
grids throughout the forecast period. Current warnings look 
reasonable and few changes should be needed on the next offshore 
waters forecast.

For wave height grids will also continue to use the current grids
throughout the forecast period.

Extratropical storm surge guidance...n/a. 

-----------------------------------------------------------------
PREVIOUS DISCUSSION...

A cold front was dissipating across the central offshore waters
early this afternoon. High pressure was to the W of the central 
offshore waters while a trof was near the California coast.
Models maintain this pattern through about Thu night and early
Fri with the high pressure area becoming weaker Thu and Thu 
night. Have not received any recent ASCAT data, but earlier and 
recent ship observations continue to show strongest winds were 
along the inner waters of the central CA waters where winds were 
to 25 kt or 30 kt. GFS/UKMET/ECMWF do show low pressure moving E 
near the nrn WA waters late Thu and Thu night while moving a 
warm front over the WA/OR waters later tonight into Thu. Another
stronger low pressure approaches the WA waters Thu night and 
moves NE passing N of the waters with an associated cold front 
moving E across WA/OR waters Fri and Fri night. The UKMET/ECMWF 
are weaker with the surface low. Preference is for the GFS/GEM 
with a stronger solution seeming more likely with all models 
similar with upper support. By late Sat into Sun night high 
pressure builds E across the nrn offshore waters with an area of 
high pressure moving E towards the waters, then stalling. The 
GFS/UKMET are both supporting gales along the coastal trof along 
the inner waters of the nrn CA and OR while the ECMWF is weaker 
with winds. Prefer the GFS/UKMET which have high pressure further
E than the ECMWF and all are similar with the high retrograding 
to the W late in period. 

Seas...Preference is with the WWIII ENP with the ECMWF wam
looking underdone with seas associated with the low pressure that
approaches the WA waters Fri and also seeming to underdone late
Mon and Mon night with coastal trof along CA/OR.

.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A high pressure 
ridge will move SE across the area tonight through Thu night. A 
warm front will move E over the waters later tonight and Thu. Low
pressure will move near the far northern portion late Thu and 
Thu night, followed by a stronger low Fri and Fri night. The 
stronger low will pass near the NW waters Fri and then move NE 
near Vancouver island Fri night. An associated cold front will 
cross the waters Fri into Fri night. High pressure will build E 
towards the area Sat through Mon night, while a low pressure 
trough develops along the coast of southern Oregon Sun and 
persists through Mon night.
