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...            

THE MONSOON TROUGH EXTENDS FROM 10N85W TO LOW PRES NEAR 08N104W 
TO LOW PRES NEAR 08N117W TO 06N125W. THE ITCZ EXTENDS FROM 
06N125W TO 04N132W TO 07N140W. NUMEROUS MODERATE SCATTERED 
STRONG CONVECTION WAS NOTED WITHIN 120 NM N OF THE MONSOON 
TROUGH BETWEEN 86W AND 89W. SCATTERED MODERATE CONVECTION WAS 
NOTED WITHIN 90 NM S OF THE MONSOON TROUGH BETWEEN 95W AND 99W. 
SCATTERED MODERATE CONVECTION WAS NOTED FROM 04N TO 12N BETWEEN 
116W AND 123W. 

...DISCUSSION...

A COLD FRONT EXTENDS FROM BAJA CALIFORNIA NORTE TO 25N125W THEN 
DISSIPATING TO 24N140W. STRONG HIGH PRESSURE IS BUILDING IN THE 
WAKE OF THE FRONT. THE PRESSURE GRADIENT BETWEEN BUILDING HIGH 
PRESSURE AND LOWER PRESSURE IN THE VICINITY OF THE ITCZ IS 
MAINTAINING AN AREA OF FRESH TO STRONG WINDS FROM FROM 13N TO 
21N W OF 132W. MODERATE TO FRESH WINDS PREVAIL ELSEWHERE N OF 
10N AND W OF 120W. SEAS ARE IN THE 8-11 FT RANGE OVER THIS 
AREA...A COMBINATION OF NW SWELL WITH NE WIND WAVES. THE COLD 
FRONT WILL DISSIPATE TODAY WITH HIGH PRESSURE BUILDING IN. THE 
STRONG HIGH PRESSURE WILL MAINTAIN A LARGE AREA OF FRESH TO 
STRONG WINDS OVER THE WESTERN WATERS N OF THE ITCZ THROUGH THE 
NEXT COUPLE OF DAYS. 
 
GULF OF CALIFORNIA...HIGH PRESSURE WILL BUILD INTO THE GREAT 
BASIN REGION WEDNESDAY. THIS WILL HELP TIGHTEN THE PRESSURE 
GRADIENT OVER THE GULF OF CALIFORNIA WITH WINDS EXPECTED TO 
STRENGTHEN BY WED AFTERNOON. 

GULF OF TEHUANTEPEC...NEAR GALE FORCE WINDS PREVAIL OVER THE 
GULF OF TEHUANTEPEC DUE TO THE PRESSURE GRADIENT BETWEEN A 
WEAKENING HIGH PRESSURE RIDGE OVER EASTERN MEXICO AND THE 
EASTERN NORTH PACIFIC MONSOON TROUGH. THE RIDGE WILL WEAKEN OVER 
THE NEXT 24-36 HOURS WITH WINDS VEERING OVER THE SW GULF OF 
MEXICO. THIS WILL DECREASE WINDS FUNNELING THROUGH THE CHIVELA 
PASS INTO THE GULF OF TEHUANTEPEC WITH WINDS AND SEAS FALLING 
BELOW ADVISORY CRITERIA WED.
