Marine Weather Discussion for N Pacific Ocean
NWS Ocean Prediction Center Washington DC
719 PM PST WED DEC 7 2016

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

I do not plan on making any changes to the current grids or
assocated text forecasts in the update package. the global models
continue to offer widely different solutions with various low
centers indicated by ECMWF. The GFS is more offers a more
consolidated soln and has been the model of choice for some time.

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

The latest model guidance continues to indicate that low pressure
currently near 40n138w will move ne through Thursday and then
slide east across the northern pz5 waters Friday and Friday night.
Still expect gales across portions of the pz5 and northern pz6
waters by late today...with storm conditions possible to the south
of the low track across portions of the pz5 waters by late Friday.
The gfs is more progressive with the low than the ecmwf. At this
time will lean more towards the faster gfs solution as the latest
ukmet looks to be in somewhat better agreement with the gfs. Another
low will then approach the pz5 waters by Sunday.

Farther south...a low pressure trof along the southern California
coast continues to combine with a high pressure ridge centered
west of the southern pz6 waters to produce northwest winds up to
25 knots off the coast of southern California with the strongest
conditions southwest of of Point Conception. These conditions will
diminish by later today and mainly light winds are expected across
most of the southern pz6 waters tonight into Saturday. For wind
grids will use the gfs 30m winds through Friday night...then
transition to the gfs 10m winds. Current warnings look reasonable
and few changes should be needed on the next offshore waters
forecast.

The ww3 looks reasonable with the seas and will be followed fairly
closely during the forecast period.

Extratropical storm surge guidance...The surge guidance continues
to show values of 0.5 to 1 foot along portions of the Washington
and Oregon coasts late Thursday into Thursday night and this looks
reasonable.
