MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
1247 AM PDT TUE MAY 24 2016

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

00Z GLOBAL MODELS IN GOOD AGREEMENT THROUGH THE FORECAST PERIOD.
WILL POPULATE WIND GRIDS WITH 10M WINDS FROM THE 00Z GFS THROUGH
MOST OF THE FORECAST PERIOD...WITH THE EXCEPTION FROM 00Z FRI
THROUGH 00Z SUN WILL LEAVE PREVIOUS GRIDS IN WITH A FEW MINOR
ADJUSTMENTS.

MAIN FORECAST FEATURES IN PLAY THROUGH THE FORECAST PERIOD WILL BE
THE EPAC HIGH AND THE COASTAL TROUGH ALONG CALIFORNIA. GLOBAL
MODELS STILL IN AGREEMENT WITH THE GRADIENT SLOWLY STRENGTHENING
BETWEEN THE TWO SYSTEMS BEGINNING WED NIGHT...AND PEAKING AROUND
THU NIGHT AND CONTINUING INTO SAT. GFS 30M WINDS STILL INDICATES
GALES EXTENDING INTO THE OFFSHORE WATERS FROM NEAR CAPE MENDOCINO
TO PIGEON POINT THU NIGHT INTO SAT...AND CLOSELY MATCHES GALES
FROM PREVIOUS FORECAST. SO WILL KEEP PREVIOUS GRIDS FROM 00Z FRI
THROUGH 00Z SUN IN ORDER TO MAINTAIN CONSISTENCY FROM PREVIOUS
FORECAST...BUT WILL MAKE SOME MINOR MODIFICATIONS TO THE GALES TO
REFLECT LATEST MODEL GUIDANCE. GREATEST CHANCE FOR GALES IS IN THE
COASTAL WATERS...WITH A POSSIBILITY OF GALES EXTENDING INTO THE
ADJACENT OFFSHORE WATERS. BOTH THE ECMWF AND UKMET DID HAVE 10M
GALES EXTENDING INTO THE NE PORTION OF THE CENTRAL PZ6 WATERS
AROUND 12Z SAT...WHICH LOOKS TO BE THE BEST CHANCE OF GALES IN THE
OFFSHORE WATERS. PATTERN BEGINS TO WEAKEN LATE SAT...WITH GALES
ENDING. FOR THE REMAINDER OF THE FORECAST PERIOD POPULATED WITH
10M WINDS FROM 00Z GFS.


.SEAS...ENP VERSION OF WWII WITHIN A FT OR TWO OF CURRENT OBS.
