MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN

NWS OCEAN PREDICTION CENTER WASHINGTON DC

739 AM PDT FRI SEP 2 2016



.FORECAST DISCUSSION: MAJOR FEATURES/WINDS/SEAS/SIGNIFICANT

.WEATHER FOR THE NORTH PACIFIC N OF 30N AND E OF 150W.



ATTM I DONT PLAN ON MAKING ANY CHANGES TO THE CURRENT GRIDS OR

ASSOCIATED TEXT FCST. THE OVERALL PATTERN OVR THE EPAC REMAINS

VERY STABLE WITH ONLY VERY WEAK BNDRIES EFFECTING THE REGION...THE

DOMINATE FORCE ALONG THE CA CST WILL CONTINUE TO BE THE LOW PRES

TROF WHICH WILL REMAIN THE FOCAL POINT FOR ENHANCED WINDS..30 KT

KT ACROSS THE COASTAL ZONES.



-----------------------------------------------------------------

PREVIOUS DISCUSSION...



THE LATEST MODEL GUIDANCE INDICATES THAT HIGH PRES CENTERED W OF

THE PZ6 WATERS CONTINUES TO COMBINE WITH INLAND LOW PRES TO

PRODUCE NW WINDS UP TO 30 KT OFF THE COAST OF CALIFORNIA WITH THE

STRONGEST CONDITIONS W OF POINT CONCEPTION AND W OF POINT ARENA.

THE HIGHEST CONDITIONS W OF POINT ARENA ARE EXPECTED TO REMAIN IN

PLACE THROUGH TUE WITH HIGHEST WINDS OF 30 KT OR SO MAINLY IN THE

COASTAL WATERS. FARTHER N...ONE WEAK LOW IS STILL EXPECTED TO DROP

SE INTO THE PZ5 WATERS BY MON AND THEN DISSIPATE. ANOTHER WEAK LOW

WILL THEN MOVE INTO THE PZ5 WATERS BY TUE. THE LATEST RUNS OF THE

GFS AND ECMWF LOOK TO BE IN REASONABLE AGREEMENT. FOR WIND GRIDS

WILL CONTINUE TO USE THE GFS 10M WINDS THROUGHOUT. CURRENT

FORECAST LOOKS REASONABLE AND WILL CONTINUE TO CARRY NO WARNINGS

ACROSS THE OFFSHORE WATERS DURING THE FORECAST PERIOD.



THE NWW3 LOOKS REASONABLE WITH THE SEAS AND WILL BE FOLLOWED

FAIRLY CLOSELY DURING THE FORECAST PERIOD.



EXTRATROPICAL STORM SURGE GUIDANCE...N/A. 







.WARNINGS...PRELIMINARY.



.PZ5 WASHINGTON/OREGON WATERS...

     NONE.



.PZ6 CALIFORNIA WATERS...

     NONE.
