MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
1238 AM PST FRI NOV 28 2014

.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 COLD FRONT EXTENDING SW FROM THE
OREGON CST ACROSS THE OFFSHORE WATERS. INADV OF BNDRY IS A VERY
SMALL AREA OF GALE WINDS ALONG THE SW OREGON CST. THE MAIN LOW
CENTER IS WELL W OF THE NRN CA WATERS. A HIGH PRES RIDGE DOMINATES
MUCH OF THE SE CA WATERS. THE 00Z GLOBAL MODELS ARE ALL PRETTY
CONSISTANT WITH THEIR PRIOR RUNS. THE ECMWF/UKMET SOLN REMAIN THE
FARTHEST W OF THE MODELS WITH THE PSN OF THE LOW CENTER AFTER DAY
2. THE GFS IS STILL SOMEWHAT OF AN OUTLIER AND REMAINS STRONGER
AND CLOSER TO THE OFFSHORE WATERS. WILL AIM TO KEEP AS MUCH
CONTINUITY AS POSS WITH THE PRV FCST AND POP THE GRIDS USING THE
ECMWF AFTER 00Z SAT. I STILL EXPECT A SMALL AREA OF GALES TO OCCUR
FRI NIGHT OVER THE NW PTN OF THE WASHINGTON OFFSHORE WATERS.
LATEST RUN BACKED OFF A BIT ON THE SRN EXTENT OF THE GALES...AND
THEREFOR ONLY EXPECT GALE CONDITIONS TO REACH NW ZONE.

SEAS...WILL USE A 50/50 BLEND OF WW3 AND ECMWF THROUGH SAT NIGHT
IN ORDER TO TAMP DOWN THE ROBUST ECMWF WAVE OUTPUT ACROSS THE
WA/OR WATERS. ONCE CONDITIONS SUBSIDE A BIT WILL POP REMAINING
GRIDS WITH ECMWF WAVE GUID.

.EXTRATROPICAL STORM SURGE GUIDANCE...N/A

.WARNINGS...PRELIMINARY.

.PZ5 WASHINGTON/OREGON WATERS...
.PZZ900...OUTER WATERS FROM CAPE FLATTERY TO CAPE SHOALWATER...
     GALE TONIGHT.

.PZ6 CALIFORNIA WATERS...
     NONE.
