TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN FROM
THE EQUATOR TO 32N...EAST OF 140W. THE FOLLOWING INFORMATION IS
BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND
METEOROLOGICAL ANALYSIS.

BASED ON 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH
0230 UTC.     
  
...INTERTROPICAL CONVERGENCE ZONE...

THE MONSOON TROUGH EXTENDS FROM 09N84W TO 11N101W TO 10N110W TO
10N115W TO 08N130W. THE ITCZ EXTENDS FROM 08N130W TO 08N137W TO
BEYOND 06N140W. SCATTERED MODERATE ISOLATED STRONG CONVECTION
WAS NOTED WITHIN 270 NM S OF THE MONSOON TROUGH BETWEEN 84W AND
90W. SCATTERED MODERATE ISOLATED STRONG CONVECTION WAS NOTED
WITHIN 180 NM S AND 150 NM N OF THE MONSOON TROUGH BETWEEN 107W
AND 115W. 

...DISCUSSION...

HIGH PRESSURE OF 1031 MB CENTERED N OF THE AREA NEAR 41N139W
EXTENDS A RIDGE SE TO NEAR 18N111W. 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 136W AND FROM 09N TO
11N BETWEEN 122W AND 132W. THE RIDGE WILL REMAIN OVER THE AREA
WITH MODERATE TO FRESH TRADES PREVAILING OVER THE WESTERN
WATERS. NW TO N SWELL CONTINUES TO AFFECT THE NORTHERN WATERS
WITH SEAS GREATER THAN 8 FT COVERING THE AREA N OF 27N BETWEEN
122W AND 131W. THIS SWELL CONTINUES TO SUBSIDE AND SEAS WILL
FALL BELOW 8 FT BY SUN AFTERNOON. 

GAP WINDS...

GULF OF TEHUANTEPEC...WINDS HAVE VEERED OVER THE GULF OF MEXICO
DECREASING WINDS FUNNELING INTO THE GULF OF TEHUANTEPEC. WINDS
HAVE DIMINISHED TO 20 KT OR LESS WITH SEAS LESS THAN 8 FT. 
   
GULF OF PAPAGAYO...THE PRESSURE GRADIENT BETWEEN HIGH PRESSURE
OVER THE GULF OF MEXICO AND LOW PRESSURE ASSOCIATED WITH THE
MONSOON TROUGH OVER THE EASTERN NORTH PACIFIC IS SUPPORTING
FRESH WINDS 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 SUNDAY DIMINISHING THE PRESSURE GRADIENT AND GAP WINDS
OVER THE GULF OF PAPAGAYO.
