MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
207 AM PDT MON SEP 22 2014

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

LATEST SAT PIX AND CURRENT OBS INDICATE COLD FRONT MOVING ACROSS
PZ5 WATERS WITH SEAS RUNNING 4-7 FT ACROSS ENTIRE REGION.
ALTIMETER PASSES FROM 05 AND 03Z ALSO MATCH UP WELL WITH CURRENT
OB REPORTS. SCAT PASS FROM 05Z SHOWS MAINLY WINDS 10-15 KT WINDS
ACROSS OFFSHORE WATERS...WITH EMBEDDED WINDS TO 20 KT...MAX WINDS
TO 25 KT CURRENTLY INDICATED NR PT CONCEPTION. THE GLOBAL MODELS
ARE ALL IN VERY GOOD AGREEMENT THROUGHOUT THE PERIOD...BUT
ESPECIALLY OVR THE FIRST 3 DAYS. AFTER 72 HRS SOME DIFFERENCES
BEGIN TO EMERGE...THE GFS/CMC TAKE THE MAIN LOW CENTER NW OF THE
WASHINGTON WATERS...WHILE THE ECMWF DIGS THE LOW SE INTO THE
WATERS...ALBEIT IN A WEAKENED STATE BY THAT POINT. THE ULMET IS
PROBABLY A GOOD COMPROMISE SOLN AND DIPS THE LOW SE INTO THE
WASHINGTON WATERS...BUT NOT AS FAR SE A THE ECMWF INDICATES. WHEN
POP THE GRIDS WILL USE THE 10M GFS THROUGHOUT THE PERIOD...EXCEPT
FOR THE STRETCH FROM 00Z WED THROUGH 21Z WED WHERE I DECIDED TO
USE THE ECMWF...WHICH IS A LITTLE QUICKER IN BRINGING GALES TO THE
PZ5 WATERS BEHIND THE INITIAL FRONTAL BOUNDARY...AS THE STRONG
LOW PRESSES E. AS FAR AS THE SEAS GO...THE WW3 LOOKS REASONABLE
THROUGHOUT. WILL POP WAVE GRIDS WITH CORRESPONDING MODEL GUID TO
MATCH THE WINDS. WILL MAKE SOME ADJUSTMENTS TO GRIDS ALONG THE
COASTAL BORDER IN ORDER TO SHOW SOME CONSISTANCY./
