marine weather discussion for N Pacific Ocean NWS ocean prediction center Washington DC 739 PM PDT sun may 24 2015
.Forecast discussion: major features/winds/seas/significant .Weather for the North Pacific N of 30n and E of 150w.
Sat img has mostly cldy skies but no ligtng strikes assctd with it ovr the frcst wtrs. The radar has no indc of tstms cells acrs the region. At 0000z hgh pres 1029 mb cntrd 300 nm W of the nrn wtrs still controls ridges ovr the nrnn wtrs and just W of the srn wtrs. Inland low pres 1008 mb ovr nrn CA has trof strcng S alng the coast. The ptre sgrdnt is just tight ovr the cntrl wtrs where Max obsvd winds are 25 kt. The seas are equally small with 9 ft peak ovr the cntrl wtrs.
An upprlvl high pres ridge with its axis just W of the region has kept all the enrgy either E of the region or W of the region. This senario will continue thru the fcst prd and so the grdnt will remain slck and no wrngs in the fcst.
The glbl mdls hv initialized well and they cntnue to be in gud agrmnt on the hgh pres and inland trof. Will still stay with GFS and nww3 for the seas. In the short term hgh pres will remain anchored to the W of the region while the inland low pres will persist but weak. The hgh pres will weaken in the xtndd prd but that wil still keep frntl sysm to the W of the region.

12z global models in good agrmt thru the fcst period. Will populate wind grids with 10m winds from the 12z GFS thru the period...which has support from both the ECMWF and the UKMET.
High pres W of the area will persist thru the fcst period...as a series of low pres troughs line up off the nrn and cntrl calif coast...as well as off the nrn coast of wash. Models showing Max winds over the offshr waters to be in the 20 to 25 kt range thru the period...with some winds to 30 kt and gusts to gale force psbl in the cstl waters off Pt St George tonight into Mon night.
.Seas...Enp version of wwiii within a ft or two of current obs. Will populate wave grids from 12z enp...with a few minor adjustments closer to the coast thru the fcst period.
.Extratropical storm surge guidance...N/A
