Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
724 PM PDT Sat Jun 23 2018

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

High pressure to the west of the region will slightly weaken and
inland trough along California coast will also start to weaken 
and that will allow pressure gradient to relax over the central 
waters in the short term. High pressure will strengthen again 
west of the region in the extended period and force a tight 
pressure gradient again over the central waters. Latest GOES16 
RGB geocolor satellite images show mostly clear of cold clouds 
but just a few warm low clouds over the region. Scatterometer 
pass at 1749Z had gale force winds over waters adjacent to 
Eureka, northern California. Latest NCEP map has high pressure 
center 1026 MB over outer Oregon waters which is part of the main
high center 1034 MB near 40N160W. inland low pressure 998 mb 
over southern California has a trough extending northwest along 
the California coast into southwestern Oregon. the combination to
both high and trough has caused a tight pressure gradient over 
the central waters where winds are in the gale force range. 
Farther northwest of the northern waters is low pressure 1003 Mb 
with gale force winds that has its warm front reaching the far 
western portion of the Washington waters while its associated 
cold front passes 180 NM west of the northern waters. This low 
pressure will move east in the short term and pass just north of 
the waters.

Seas have a peak at 13 ft near Cape Mendocino, northern 
california waters. Otherwise seas range between 5 and 12 ft over 
the California waters while they range between 3 and 6 ft over 
the Washington and Oregon offshore waters. Both wave models NWW3 
and ECMWFWAVE fit well the observed seas pattern and have been 
quite consistent and therefore will not deviate from the previous
model choice but will just stay with ENP for seas.

At 500 MB, an upper level ridge lies over the western portion of
the forecast waters. In the short term, some energy embedded a 
trough to the north will move east and pass just north of the 
region as the ridge weakens. the ridge will build again in the 
extended period. As such the current gales will diminish before 
another round of gales in the extended period. The global models 
have initialized well the latest surface observations and they 
are in a good agreement in the short term on weakening the high 
pressure over the north waters. Will stay with GFS for winds.

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

Have not had any recent satellite derived winds across the 
offshore waters since 06Z. There was a ship observation at 18Z 
over the inner waters of the central CA waters which showed 37 
kt. This may be slightly too high with QC history showing about 
22 observations in the database and a plus 2.7 kt plus wind bias.
Will have Gales in the waters along inner waters of the central 
and nrn CA through tonight with model guidance indicating 
strongest pressure gradient developing between the coastal trof 
and high pressure through at least early tonight. Later tonight a
cold front approaches the nrn and central areas of the offshore 
waters and crosses the area Sun. A broad area of high pressure
builds in across the N and central areas of the offshore waters
Sun through Tue. Will continue to have winds to 30 kt over the
inner waters of the central and nrn CA with the potential for
gales over this area late Mon night into Tue. GFS still shows a
cold front crossing into the nrn offshore waters late Wed and Wed
night while UKMET/ECMWF are slower with moving the front into the
waters. Will continue to favor the GFS guidance which remains
weak with the associated winds. GFS model shows a trof or weak 
cold front moving towards or into the waters late Thu and Thu 
night. 

Seas...At 18Z seas were analyzed a bit higher to 15 ft than 
guidance over the inner waters of CA. This could be a bit too
high, but have seen any jason data to indicate lower values. 
Otherwise seas were close to both the WWIII ENP and ECMWF wam. 
Both the WWIII and ECMWF wam are in close agreement throughout 
the forecast period and will use a blend of 50/50 for the seas 
after about 06Z tonight.

Washington and Oregon waters-
Inner waters from  60 nm to 150 nm offshore.
Outer waters from 150 nm to 250 nm offshore.

Seas given as significant wave height, which is the average
height of the highest 1/3 of the waves. Individual waves may be

828 PM PDT Sat Jun 23 2018

.SYNOPSIS FOR WASHINGTON AND OREGON WATERS...A high pressure
ridge over the waters will weaken tonight. A low pressure trough
along the Oregon coast will slowly strengthen tonight, then 
weaken and dissipate Sun. A weakening cold front will move E 
across the waters Sun and early Sun night. A trough will move E 
over the area Sun night into Mon. A strong high pressure ridge 
will build E across the waters Sun through Mon night, then stay W
and SW of the waters while gradually becoming weaker through Tue
night. A cold front will move E over the waters late Wed and Wed
night. High pressure will rebuild over the area Thu with a 
trough moving E into the waters Thu night.

.SYNOPSIS FOR CALIFORNIA WATERS...A high pressure ridge W of the
area will weaken tonight. A cold front will move SE over the N 
waters late Sun and Sun night. A low pressure trough along the 
California coast will slowly intensify across the northern and 
central areas tonight. Another area of high pressure will build 
in from the W and NW Sun through early Tue, then gradually weaken
through Tue night. The low pressure trough will weaken Sun and 
shift further inland Sun night into Mon, then redevelop near the 
N and central coast Tue and Tue night and persist through Thu 
night. The area of high pressure will remain W of the area while 
drifting W Wed and Wed night, then be W and NW of the waters Thu 
and Thu night.
