MARINE WEATHER DISCUSSION FOR N PACIFIC OCEAN
NWS OCEAN PREDICTION CENTER WASHINGTON DC
725 PM PDT TUE SEP 27 2016

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

THE LATEST MODEL GUIDANCE INDICATES THAT AN INLAND LOW PRES TROF
CONTINUES TO COMBINE WITH A HIGH PRES RIDGE W OF THE PZ5 WATERS TO
PRODUCE NRLY WINDS UP TO 30 KT OR SO W OF POINT ST GEORGE. THESE
CONDITIONS WILL THEN SLOWLY DIMINISH TONIGHT AND WED. BY THU NIGHT
MAINLY LIGHT WINDS ARE EXPECTED ACROSS MOST OF THE OFFSHORE
WATERS. BY THU NIGHT WEAK LOW PRES WILL MOVE SE INTO THE PZ5
WATERS...THEN DISSIPATE BY SAT AS ANOTHER LOW MOVES SE INTO THE
WASHINGTON OFFSHORE WATERS. A FRONTAL SYSTEM WILL THEN APPROACH
THE PZ5 WATERS BY LATE SUN. FARTHER S...NW WINDS ARE STILL
EXPECTED TO INCREASE TO 30 KT W OF POINT CONCEPTION BY LATE
SAT...THEN CONTINUE INTO MON. FOR WIND GRIDS WILL CONTINUE TO USE
THE PREVIOUS GRIDS THROUGHOUT THE FORECAST PERIOD. CURRENT
FORECAST LOOKS REASONABLE AND WILL CONTINUE TO CARRY NO WARNINGS
ACROSS THE OFFSHORE WATERS DURING THE FORECAST PERIOD.

FOR WAVE GRIDS WILL ALSO CONTINUE TO USE THE PREVIOUS GRIDS
THROUGHOUT THE FORECAST PERIOD.

EXTRATROPICAL STORM SURGE GUIDANCE...N/A.

-----------------------------------------------------------------
PREVIOUS DISCUSSION...

THE ONLY MAJOR MODEL GUIDANCE DIFFERENCE IS SUN WHERE THE GFS
BRINGS A STRONG LOW ACROSS THE PZ5 WATERS. THE UKMET AND ECMWF
KEEP THIS WEAKER AND FURTHER S. AS SUCH...CHOICE TO GO WITH THE
ECMWF FROM SUN AND BEYOND...BUT KEPT WINDS SLIGHTLY HIGHER THAN
THE ECMWF WINDS. EXPECT WINDS WILL REACH 30 KT AND MAY NEED THIS
TO REVISIT IN LATER FORECAST PACKAGES TO MAKE SURE THAT NO
WARNINGS ARE NECESSARY. CURRENTLY NOT ADDING ANY WARNINGS TO THE
FORECAST AS THE GFS SEEMS TO BE TOO STRONG WITH THIS LOW. WILL USE THE
GFS THROUGH SAT NIGHT AS THE MODEL AGREEMENT WAS STRONG...THEN USE THE
ECMWF BEYOND THAT.

.SEAS...WILL USE WW3 UNTIL SAT NIGHT...THEN SWITCH TO THE ECMWF
WAVE MODEL.


.EXTRATROPICAL STORM SURGE GUIDANCE...N/A



.WARNINGS...PRELIMINARY.

.PZ5 WASHINGTON/OREGON WATERS...
     NONE.

.PZ6 CALIFORNIA WATERS...
     NONE.
