...DISCUSSION... 

THE STRONG COLD FRONT WHICH MOVED ACROSS THE NORTHERN WATERS 
THAT BROUGHT GALE FORCE WINDS AND LARGE NW SWELL TO THE AREA HAS 
DISSIPATED. ALTIMETER DATA AND SHIP OBSERVATIONS INDICATE SEAS 
OF 8 TO 12 FT IN NW SWELL THAT WAS USHERED IN BY THE FRONT 
PERSISTS OVER MUCH OF THE WATERS W OF 110W. SEAS OF 8 FT OR 
GREATER REACH AS FAR E AS 105W. THE NW SWELL IN EXCESS OF 8 FT 
WILL GRADUALLY DECAY OVER THE NEXT 48 HOURS AS IT SPREADS 
EASTWARD TO 95W.  

FRESH TO STRONG SOUTHERLY WINDS ARE NOTED OVER THE FAR NW WATERS 
N OF 28N W OF 138W. THESE WINDS ARE ASSOCIATED WITH A COMPLEX 
LOW PRESSURE SYSTEM CENTERED WELL N OF HAWAII NEAR 45N158W. THE 
S TO SW FLOW WILL DIMINISH LATE MON AS THE SUPPORTING UPPER 
TROUGH PIVOTS TO THE NE. A SECOND UPPER LEVEL IMPULSE WILL MOVE 
TO THE NW OF THE AREA MON INTO TUE BRINGING ANOTHER ROUND OF 20 
TO 25 KT WINDS TO THE AREA N OF 26N W OF 135W BY TUE AFTERNOON. 
A SET OF NW SWELLS ASSOCIATED WITH THIS SYSTEM HAS PROPAGATED 
INTO THE NW WATERS WITH SEAS 8 TO 11 FT COVERING THE WATERS NW 
OF A LINE FROM 30N133W TO 24N140W. THE SEAS WILL CONTINUE TO 
BUILD OVER THE FAR NW WATERS AND PEAK NEAR 16 TO 17 FT EARLY MON
