2100 UTC.     
  
...INTERTROPICAL CONVERGENCE ZONE...

THE MONSOON TROUGH EXTENDS FROM 09N84W 11N94W TO 09N118W TO
07N125W TO 07N130W. THE ITCZ EXTENDS FROM 07N130W TO 07N136W TO

AND 116W.

...DISCUSSION...

HIGH PRESSURE OF 1031 MB CENTERED N OF THE AREA NEAR 40N139W
EXTENDS A RIDGE SE TO NEAR 17N111W. THE PRESSURE GRADIENT
BETWEEN THE AREA OF HIGH PRESSURE AND LOWER PRESSURE IN THE
VICINITY OF THE ITCZ IS SUPPORTING MODERATE TO FRESH TRADES OVER
THE WESTERN WATERS N OF THE ITCZ. SW SWELL IS MIXING WITH
TRADEWIND SWELL OVER THE WESTERN WATERS WITH SEAS GREATER THAN 8
FT COVERING THE AREA FROM 08N TO 18N W OF 135W AND FROM 08N TO
11N BETWEEN 125W AND135W. THE RIDGE WILL PREVAIL OVER THE AREA
WITH MODERATE TO FRESH TRADES PREVAILING OVER THE WESTERN
WATERS. NW TO N SWELL CONTINUES TO AFFECT THE NORTHERN WATERS

FUNNELING ACROSS THE GULF OF PAPAGAYO. THIS WILL COMBINE WITH
NOCTURNAL DRAINAGE FLOW DURING THE OVERNIGHT HOURS AND WINDS
WILL INCREASE TO 25 KT OVER THE GULF OF PAPAGAYO. THE HIGH
PRESSURE CENTERED OVER THE GULF OF MEXICO WILL RETREAT EASTWARD
