THE STRONG COLD FRONT WHICH MOVED ACROSS THE NORTHERN WATERS

BECOME DIFFUSE. ALTIMETER DATA AND SHIP OBSERVATIONS INDICATE 
SEAS OF 8 TO 14 FT IN NW SWELL THAT WAS USHERED IN BY THE FRONT

SPREADS EASTWARD TO 100W.  

MODERATE TO FRESH SOUTHERLY WINDS ARE NOTED OVER THE FAR NW

DISCUSSION AREA N OF 28N AND W OF 135W TONIGHT INTO EARLY MON. 
THESE WINDS WILL DIMINISH LATER MON AS THE SUPPORTING UPPER

A SET OF NW SWELLS ASSOCIATED WITH THIS SYSTEM HAS PROPAGATED
