MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
1252 AM PDT FRI MAY 29 2015

.FORECAST DISCUSSION: MAJOR FEATURES/WINDS/SEAS/SIGNIFICANT
.WEATHER FOR THE NORTH PACIFIC N OF 30N AND E OF 150W.

THE 06Z SFC ANALYSIS INDICATED A HIGH PRES RIDGE EXTENDING FROM
GULF OF AK SE TO THE FAR WRN PORTION OF OFFSHORE WATERS. AN ASCAT
PASS FROM LATE THU EVENING INDICATED WINDS AROUND 20 KT OVER THE
ERN PORTION OF THE N/CENTRAL CA WATERS AND OVER THE WA WATERS.
OTHERWISE...WINDS WERE LESS THAN 20 KT.

THE 00Z MODELS CONTINUE TO BE IN DECENT AGREEMENT DURING THE
UPCOMING FCST PERIOD. THE MOST SIGNIFICANT FEATURE TO AFFECT THE
AREA WILL BE A WEAK LOW PRES WHICH IS FCST TO PASS ACROSS THE NRN
CA WATERS SUN NIGHT BEFORE DISSIPATING EARLY MON. OTHERWISE...HIGH
HIGH PRES RIDGE WILL DOMINATE TODAY INTO SAT BEFORE WEAKENING SAT
NIGHT...THEN REBUILD AGAIN LATER MON INTO TUE. IT LOOKS LIKE
TROUGH WILL STRENGTHEN ALONG THE CENTRAL CA COAST BY NEXT
TUE...AND ESPECIALLY TUE NIGHT...HOWEVER WINDS WILL CONTINUE TO
REMAIN BELOW GALE. WILL POPULATE WIND GRIDS USING THE 10M GFS
WINDS THROUGH TUE NIGHT AND BEYOND.

.SEAS...THE 06Z SEA STATE ANALYSIS INDICATED THAT OBSERVED SEAS
CONTINUE TO MATCH UP WELL WITH THE MWW3 FCST VALUES. WILL POPULATE
GRIDS USING THE 00Z MWW3 THROUGH THE PERIOD. BY LATER SUN EXPECT
SLIGHTLY HIGHER SEAS OVER CENTRAL/S CA WATERS AS S TO SW SWELL
FROM TROPICAL STORM ANDRES CURRENTLY WELL S OF AREA EXPANDS N.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A.

.WARNINGS...PRELIMINARY.

.PZ5 WASHINGTON/OREGON WATERS...
     NONE.

.PZ6 CALIFORNIA WATERS...
     NONE.
