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

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



ASCAT PASS FROM 06Z INDICATES A SWATH OF 25-30 KT WINDS ACROSS THE

WRN PTNS OF THE WASHINGTON AND OREGON WATERS. WINDS ACROSS THE CA

WATERS ARE 20 KT OR LESS WITH MAX WINDS ACROSS THE FAR NW PORTION.

AN ALTIMETER PASS FROM 03Z SHOWS SEAS TO 13 FT OVR THE SW OREGON

WATERS.



THE OVERALL FORECAST HASNT CHANGED MUCH OVER THE PAST FEW MODEL RUNS.

THE MAX WINDS AND SEAS WILL BE DETERMINED BY THE LOCATION OF THE

STRONGEST PRESSURE GRADIENT. THE AREA OF HIGH PRES THAT HAS BEEN

SITUATED W OF THE WA/OR WATERS WILL SLOWLY SHIFT W DURING THE NEXT

COUPLE OF DAYS BEFORE BUILDING BACK E LATER IN THE PERIOD. THE

WINDS ACROSS THE SRN AND CENTRAL CA WATERS WILL REMAIN RELATIVELY

LIGHT DURING THE UPCOMING WEEK...GENERALLY 15 KT OR LESS. THE 00Z

GLOBAL MODELS ARE IN VERY GOOD AGREEMENT WITH ONLY MINOR

DIFFERENCES INDICATED. I WILL POP THE WIND GRIDS USING A 50/50

BLEND OF THE 10M AND 30M GFS THROUGHOUT THE FORECAST.



SEAS...BOTH THE ENP AND WAM INITIALIZED WELL ACROSS THE REGION

WITH VERY LITTLE DIFFERENCES INDICATED...ESPECIALLY DURING THE

FIRST SEVERAL DAYS. WILL POP THE WAVE GRIDS USING A 50/50 BLEND OF

THE 2 WAVE MODLES IN ORDER TO GAIN A GOOD CONSENSUS.
