Marine Weather for HS 102


marine weather discussion for N Pacific Ocean NWS ocean prediction center Washington DC 134 am PDT Sat Mar 25 2017

.Forecast discussion...Major features/winds/seas/significant .Weather for the North Pacific N of 30n and E of 150w.

At 06z a high pressure ridge extended across the pz5 waters down into the northern and southern parts of the pz6 waters. A cold front extended northeast to southwest across the central pz6 waters. Ascat high resolution pass from near 0555z revealed 10-20 kt winds over the pz5...most of the pz6 waters W of 121w...except for the inner central pz6 waters were winds as low as 5 kt were noted.

Continued good agreement through Mon morning when viewing the 00z model package...hence populated through Mon morning with the 00z GFS which still results in current warning headlines remaining in place. Good confidence in pre-frontal gales ahead of the cold front progged to move through the waters Sat night into sun. Beyond that period there are some differences in regards to exact location and timing of low pressure expected to slide somewhere north of the pz5 waters Mon night into Tue with the 00z UKMET having the strongest solution at the moment. However...despite the differences to the north...further south of the pz6 waters guidance remains in good agreement in terms of strengthening north to northwesterly winds across parts of the central and southern pz6 waters as the pressure gradient tightens in response to inland troughing and a high pressure ridge to the west. That said because of the differences noted over the pz5 waters feel it's reasonable to not make adjustments to the grids at all beyond Mon morning at this point. Hence winds will continue to remain below warning criteria over parts of the central and southern pz6 waters for now...though again possibility of gales will continue to be monitored.

.Seas...Populated using 00z nww3 through about sun 06z then from sun 12z on continued with ongoing grids which consisted of blend of the 12z nww3/ECMWF wam with additional adjustment to the seas in the pre-frontal gales.

.Extratropical storm surge guidance...N/A.


.Pz5 Washington/Oregon waters... .pzz800...inner waters from Cape Flattery to Cape Shoalwater... gale Sunday. .Pzz900...Outer waters from Cape Flattery to Cape Shoalwater... gale tonight into Sunday. .Pzz805...Inner waters from Cape Shoalwater to Cape Lookout... gale Sunday. .Pzz810...Inner waters from Cape Lookout to Florence or... gale Sunday. .Pzz815...Inner waters from Florence or to point St. George... gale Sunday.
