MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN 
NWS OCEAN PREDICTION CENTER WASHINGTON DC
1155 PM PDT FRI 3 JUL 2009 

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

THERE APPEARS TO BE NO NEED FOR MAJOR CHANGES TO THE ONGOING OPC 
OFF FCST AGAIN TONITE. THE 00Z GLBL MDLS ARE IN DECENT AGREEMENT 
ACROSS THE REGION WITH THE 00Z GFS REMAINING FAIRLY CONSISTENT 
OVR ITS PAST COUPLE OF RUNS...AND HAS DECENT AGREEMENT WITH THE
00Z ECMWF...00Z UKMET AND 00Z CANADIAN GLBL MDLS THRU TUE OVR THE
AREA. WE STILL BELIEVE THAT THE 00Z GFS CONTINUES TO BE TOO QUICK
IN MOVG THE UPR LOW E AWAY FROM THE AREA BY THE MIDDLE OF NEXT 
WK. WE ALSO BELIEVE THAT THE GFS IS REMAINING A LITTLE TO STRONG
WITH ITS PRES GRAD OFF THE SOCAL AND SE CENTRAL CAL COAST BY
EARLY NEXT WK...AS THE MAJORITY OF THE NON-GFS MDLS DO NOT 
TIGHTEN THE PRES GRAD ENUF TO WARRANT GALES FOR NE SOCAL AND SE
CENTRAL CAL OFF WTRS BY TUE AND WED. THEREFORE...WE WILL KEEP MAX
WINDS AT 30 KT FOR NOW OVR THESE WTRS...OR SOMETHING VRY SIMILIAR
TO WHAT WAS INDICATED BY THE PAST OPC FCSTS.

SEAS...FOR THE MOST PART WE WILL ONCE AGAIN STAY CLOSE TO THE 
00Z WAVE WATCH III MDL OUTPUT FOR THIS FCST PACKAGE. WE WILL 
CONT TO TRIM ITS OUTPUT BY A FT OR SO EARLY NEXT WK OVR SE 
CENTRAL AND NE SOCAL OFF WTRS AS WE ARE NOT GOING QUITE AS HIGH 
AS THE 00Z GFS BL WINDS OVR THESE WTRS EARLY NEXT WK.
