BASED ON SATELLITE IMAGERY...WEATHER OBSERVATIONS...RADAR...AND 
METEOROLOGICAL ANALYSIS.

BASED ON 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
1530 UTC.

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

MONSOON TROUGH EXTENDS FROM 13N88W TO 09N110W TO 07N115W. THE

THE ITCZ FROM 06N TO 11N BETWEEN 106W AND 114W...AND FROM 04N TO 
11N BETWEEN 120W AND 130W.

...DISCUSSION...

AT THE SURFACE...
A 1030 MB HIGH IS CENTERED JUST N OF THE AREA AT 33N136W. A WEAK 
GALE IS ALSO FURTHER E OFF THE COAST OF S CALIFORNIA. 20-25 KT N 
WINDS ARE OVER THE NW AREA N OF 24N E OF 123W TO COAST OF BAJA 
CALIFORNIA PENINSULA. OVER THE NEXT 24-48 HOURS NE TO N SWELL 
WILL PUSH SW.    

IN THE TROPICS...
A 1010 MB LOW IS CENTERED NEAR 10N128W. WINDS ARE 20 KT WITH
