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 
0215 UTC.

...SPECIAL FEATURES...

A 1007 MB BROAD LOW PRES AREA LOCATED NEAR 12N94W OR ABOUT 300 
MILES S-SE OF PUERTO ANGEL, MEXICO HAS BECOME BETTER DEFINED 
TODAY. SCATTERED MODERATE AND ISOLATED STRONG CONVECTION IS 
WITHIN 390 NM IN THE SW SEMICIRCLE. FRESH TO STRONG WINDS AND 8-
9 FT SEAS ARE LOCATED AROUND THE LOW IN THE SOUTHERN PORTION. 
THE LOW IS FORECAST TO MOVE LITTLE DURING THE NEXT 24 HOURS... 
THEN MAY DRIFT TO THE N. MEANWHILE FRESH TO STRONG WINDS WILL 
PERSIST WITH SEAS BUILDING TO 10 FT BY 24-48 HOURS. THE LOW HAS 
A HIGH CHANCE OF TROPICAL CYCLONE FORMATION THROUGH THE NEXT 48 
HOURS.

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

THE MONSOON TROUGH AXIS EXTENDS FROM 09N78W TO 14N92W...THEN 
RESUMES FROM 12N110W TO 08N119W. THE ITCZ AXIS EXTENDS FROM 
08N119W TO 06N126W TO LOW PRES NEAR 08N139W TO BEYOND 06N140W. 
SCATTERED MODERATE AND ISOLATED STRONG CONVECTION IS FROM 03N TO 
10N BETWEEN 85W AND 89W. 

...DISCUSSION...     

POST-TROPICAL REMNANT LOW AMANDA AT 1007 MB IS CENTERED NEAR 
17N110W. NO ASSOCIATED DEEP CONVECTION REMAINS NEAR THE CENTER 
AND WINDS AND SEAS ARE BELOW A STRONG BREEZE AND 8 FT 
RESPECTIVELY. THE CIRCULATION AROUND THE SYSTEM IS EXPECTED TO 
ELONGATE OVER THE NEXT 12-18 HOURS. 
 
1034 MB SUBTROPICAL HIGH PRES IS WELL NORTHWEST OF THE 
DISCUSSION AREA NEAR 40N142W WITH A RIDGE AXIS EXTENDING 
SOUTHEASTWARD INTO THE REGION THROUGH 32N132W TO 22N111W. THE 
SUBTROPICAL HIGH IS FORECAST TO STRENGTHEN THROUGH THE REMAINDER 
OF THE WEEKEND. THE PRESSURE GRADIENT ACROSS THE W CENTRAL 
WATERS BETWEEN THE SUBTROPICAL RIDGE AND LOWER PRES ASSOCIATED 
WITH THE ITCZ IS SUPPORTING FRESH BREEZE AND RESULTANT SEAS TO 8 
FT FROM 14N TO 17N W OF 136W...WHICH WILL PERSIST THROUGH 48 
HOURS.

CROSS EQUATORIAL SW SWELL AT 8-9 FT CONTINUES TO IMPACT THE 
WATERS ALONG AND TO THE S OF EQUATOR W OF 81W. THESE SEAS WILL 
DECAY DURING THE NEXT 24 HOURS WHILE SHRINKING TO THE S...THEN 
WILL BE REINFORCED BY A NEW SET OF SOUTHERLY SWELL ON MON 
PUSHING THE EDGE OF SEAS AT 8 FT TO 03N.
