MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN

NWS OCEAN PREDICTION CENTER WASHINGTON DC

125 AM PDT WED SEP 7 2016



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

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



THE LATEST MODEL GUIDANCE INDICATES THAT HIGH PRES W OF THE NRN

PZ6 WATERS CONTINUES TO COMBINE WITH A LOW PRES TROF OVER

CALIFORNIA TO PRODUCE N TO NW WINDS UP TO 30 KT OR SO OFF THE

COAST OF NRN AND CENTRAL CALIFORNIA WITH THE STRONGEST CONDITIONS

W OF POINT ARENA. MINIMAL GALES ARE LIKELY TONIGHT W OF POINT

ARENA AND POINT REYES. BY LATE WED THE STRONGEST CONDITIONS WILL

SHIFT N TO OFF OF CAPE MENDOCINO WITH MINIMAL GALES AGAIN A

POSSIBILITY. A BETTER CHANCE OF GALES WILL OCCUR BY THU NIGHT W OF

POINT SAINT GEORGE AS THE THERMAL TROF STRENGTHENS OVER NRN

CALIFORNIA. THESE GALE CONDITIONS WILL THEN CONTINUE INTO FRI

BEFORE DIMINISHING SOMEWHAT. HURRICANE NEWTON IS STILL EXPECTED TO

REMAIN S AND E OF THE SRN PZ6 WATERS TONIGHT AND WED. THE LATEST

RUNS OF THE GFS AND ECMWF LOOK TO BE IN REASONABLE AGREEMENT

THROUGH SUN. FOR WIND GRIDS WILL USE THE GFS 30M WINDS THROUGHOUT

THE FORECAST PERIOD WITH SOME EDITS. ONLY CHANGE TO WARNINGS WILL

BE TO ADD SOME MINIMAL GALES W OF CAPE MENDOCINO FOR WED NIGHT.

OTHERWISE CURRENT WARNINGS LOOK REASONABLE AND FEW CHANGES SHOULD

BE NEEDED ON THE NEXT OFFSHORE FORECAST.



THE NWW3 LOOKS REASONABLE WITH THE SEAS AND WILL BE FOLLOWED

FAIRLY CLOSELY DURING THE FORECAST PERIOD.
