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

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



NO CHANGES ARE PLANNED FOR THE MORNING UPDATE. THE 06Z GFS WAS

VERY CLOSE TO THE 00Z GFS THROUGHOUT THE FCST PERIOD...AND IS ALSO

IN AGREEMENT WITH THE OTHER 00Z MODELS. THE 12Z SEA STATE ANALYSIS

INDICATED THAT OBSERVED SEAS MATCHED UP WELL WITH THE MWW3 FCST

VALUES...SO WILL ALSO NOT NEED TO MAKE ANY ADJUSTMENTS TO WAVE

GRIDS. 



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

PREVIOUS DISCUSSION...



VERY SIMPLE AND FAMILIAR PATTERN WILL PERSIST TODAY AND THRUT THE

UPCOMING WEEK AS EPAC HIGH PRES COMBINES WITH COASTAL LOW PRES

TROFS TO CREATE PERSISTENT N TO NW FLOW ACROSS MOST OF THE OPC

AOR. NO WARNING HEADLINES WILL BE NEEDED AND THE STRONGEST

SUSTAINED WINDS TO 30 KT ARE EXPECTED TO OCCUR TODAY INTO TONIGHT

- AS IS USUALLY THE CASE - WITHIN THE COASTAL ZONES FROM SW OF

CAPE BLANCO TO NEAR POINT ST GEORGE. NOT SURPRISINGLY THE 00Z

MODEL SUITE REMAINS IN GREAT AGREEMENT ON THE BASIC PATTERN AND

SEE NO REASONS TO STRAY FAR FROM 00Z GFS OUTPUT THIS MORNING.



SEAS...SIMILARLY WILL USING THE 00Z ENP WW3 AS THE BASIS FOR THE

SIG WVHT GRIDS.



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





.WARNINGS...PRELIMINARY.
