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 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0900 UTC. 

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...
            
MONSOON TROUGH EXTENDS FROM 14N110W TO 07N127W. ITCZ EXTENDS 
FROM 07N127W TO 06N140W. NO SIGNIFICANT CONVECTION.

...DISCUSSION... 

1026 MB HIGH PRESSURE N OF THE AREA NEAR 33N132W EXTENDS A RIDGE 
SE TO NEAR 21N114W. WEAK PRESSURE GRADIENT BETWEEN THE HIGH AND 
LOWER PRESSURE IN THE VICINITY OF THE ITCZ IS SUPPORTING GENTLE 
TO MODERATE TRADES IN WESTERN WATERS N OF THE CONVERGENCE ZONE. 
MUCH OF THE AREA IS BELOW ADVISORY CRITERIA EXCEPT FOR A SMALL 
AREA OF NORTHERLY SWELLS N OF 28N BETWEEN 120W AND 128W. THIS 
SMALL AREA OF NORTHERLY SWELLS IS WILL CONTINUE ANOTHER 18-24 
HOURS BEFORE SUBSIDING BELOW 8 FT BY FRI MORNING. 
 
THERE ARE NO ONGOING GAP WIND EVENTS THAT EXCEED 20 KT WINDS OR 
SEAS TO 8 FT...AND NONE ARE EXPECTED TO DEVELOP DURING THE NEXT 
3-4 DAYS. THIS IS AN INDICATION THAT WINTER SEASON IS WINDING 
DOWN AS WE MOVE INTO THE TRANSITIONAL SPRING SEASON. THIS MEANS 
FEWER STRONG COLD FRONTS PUSHING FAR SOUTH INTO THE TROPICS WITH 
AREAS OF STRONG HIGH PRESSURE IN THE WESTERN CARIBBEAN AND SW 
GULF OF MEXICO HELPING INDUCE STRONG DIURNAL WINDS THROUGH USUAL 
GAP WIND LOCATIONS SUCH AS GULFS OF TEHUANTEPEC AND PAPAGAYO.
