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 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2100 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH... 

DISCONTINUOUS MONSOON TROUGH EXTENDS FROM 10N84W TO 07N88W THEN 
MAIN PORTION RESUMES FROM 1010MB LOW PRES CENTERED NEAR 16N110W 
TO 09N118W WHERE IT TRANSITIONS TO AN ITCZ...THAT EXTENDS TO 
08N128W TO 06N140W. NUMEROUS MODERATE CONVECTION FROM 05N TO 09N 
BETWEEN 80W AND 88W.

...DISCUSSION...

TROPICAL DEPRESSION BARBARA LOSING ITS ENERGY OVER THE ISTHMUS 
OF TEHUANTEPEC WITH THE REMNANT LOW HUGGING THE COAST OF MEXICO 
IN THE SOUTHERN BAY OF CAMPECHE. ENHANCED W-NW WINDS CONTINUE N 
OF 14N BETWEEN 95W AND 105W...WHILE HIGH SEAS GENERATED BY THE 
TROPICAL CYCLONE ARE SUBSIDING ACROSS THE AREA N OF 10N BETWEEN 
90W AND 100W. EXPECT WINDS AND SEAS TO RAPIDLY DIMINISH TONIGHT 
AND FRI AS THE DRIVING FORCE FOR THE HAZARDOUS MARINE CONDITIONS 
DISSIPATES OVER SOUTHERN MEXICO. 

SUBTROPICAL HIGH CENTERED NEAR 34N136W AND THERMAL TROUGH OVER 
THE MOJAVE DESERT AND NORTHERN BAJA CALIFORNIA IS SUPPORTING 
STRONG TO NEAR GALE N-NW WINDS ALONG THE COAST OF CENTRAL AND 
SOUTHERN CALIFORNIA...WHICH ARE GENERATING SEAS TO 12 FT N OF 
30N WHICH ARE SPREADING SOUTHWARD AS N-NW SWELL N OF 25N BETWEEN 
117W AND 124W. EXPECT VERY LITTLE CHANGE TO THE SYNOPTIC PATTERN 
DURING THE NEXT FEW DAYS...THE SUBTROPICAL HIGH WILL REMAIN 
NEARLY STATIONARY NEAR 35N135W WHILE THE THERMAL TROUGH OVER THE 
DESERT SOUTHWEST WEAKENS SLIGHTLY. THIS WILL ALLOW STRONG 25-30 
KT N-NW WINDS TO CONTINUE ALONG THE CALIFORNIA COAST AND ALLOW 
LARGE SWELL TO SWEEP S OF 30N INTO THE NE PORTION OF THE AREA.

MODERATE TO FRESH TRADE WINDS WILL PREVAIL N OF THE CONVERGENCE 
ZONE W OF 120W THROUGH THE WEEKEND WITH SEAS GENERALLY 6-7 FT 
ACROSS THE REGION. LONG PERIOD SOUTHERN HEMISPHERE SW SWELLS 
WILL DOMINATE THE EQUATORIAL WATERS E OF 120W THROUGH MON.
