0405 UTC TUE SEP 03 2013

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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0230 UTC.
                
...SPECIAL FEATURES... 

LOW PRESSURE IS EMBEDDED WITHIN THE MONSOON TROUGH NEAR 
15.5N102W. ENVIRONMENTAL CONDITIONS ARE FAVORABLE FOR SLOW 
DEVELOPMENT OF THE SYSTEM AND THE LATEST NHC TROPICAL WEATHER 
OUTLOOK GIVES THIS LOW PRESSURE AREA A MEDIUM CHANCE OF 
DEVELOPING INTO A TROPICAL CYCLONE WITHIN THE NEXT 48 HOURS. 

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...              
 
THE MONSOON TROUGH EXTENDS FROM 10N85W TO 11N95W TO LOW PRES 
NEAR 15.5N102W 1008 MB AND RESUMES FROM 13N119W TO LOW PRES NEAR 
14.5N124W 1009 MB TO 13N130W TO LOW PRES NEAR 14N136W 1010 MB TO 
11N140W. SCATTERED MODERATE ISOLATED STRONG CONVECTION WAS NOTED 
WITHIN 180 NM N OF TROUGH BETWEEN 96W AND 100W. SCATTERED 
MODERATE CONVECTION WAS NOTED WITHIN 240 NM S OF TROUGH BETWEEN 
119W AND 140W. 

...DISCUSSION...

POST TROPICAL CYCLONE KIKO IS CENTERED NEAR 23N 116.5W. THERE 
REMAINS NO SIGNIFICANT CONVECTION ASSOCIATED WITH KIKO. KIKO 
WILL CONTINUE TO WEAKEN AND IS EXPECTED TO DISSIPATE COMPLETELY 
BY WED. THERE ARE A PAIR OF WEAK LOW PRES SYSTEMS EMBEDDED 
WITHIN THE MONSOON TROUGH W OF 120W...ONE NEAR 14.5N124W AND THE 
OTHER NEAR 14N136W. NEITHER OF THESE LOW PRESSURE CENTERS ARE 
EXPECTED TO DEVELOP INTO A TROPICAL SYSTEM. ASIDE FROM KIKO 
MARINE CONDITIONS ACROSS THE ENTIRE FORECAST AREA ARE QUITE 
BENIGN DUE A VERY WEAK PRES GRADIENT. THIS PERIOD OF UNUSUALLY 
LIGHT WINDS AND SEAS IS EXPECTED FOR AT LEAST THE NEXT 24 HOURS.
