NWS NATIONAL HURRICANE CENTER MIAMI FL
1005 UTC FRI AUG 30 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 ON 0600 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0900 UTC.
                                
..INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...               

THE MONSOON TROUGH EXTENDS FROM 08N78W TO 07N98W TO 11N109W... 
THEN RESUMES AT 1009 MB LOW PRES NEAR 16N115W TO 13N120W TO 1009 
MB LOW PRES NEAR 12N130W TO 10N140W. SCATTERED MODERATE ISOLATED 
STRONG CONVECTION WITHIN 180 NM NE SEMICIRCLE OF LOW PRES NEAR 
16N115W. SCATTERED MODERATE ISOLATED STRONG CONVECTION WITHIN 
180 NM SW SEMICIRCLE OF LOW NEAR 12N130W.

...DISCUSSION...

REMNANT LOW FORMERLY JULIETTE IS RAPIDLY WEAKENING OVER COLD 
WATER W OF BAJA CALIFORNIA. 

A WEAK RIDGE EXTENDS SE FROM 1020 MB HIGH NEAR 31N130W. TWO LOW 
PRESSURE CENTERS ARE EMBEDDED WITHIN THE MONSOON TROUGH...ONE 
NEAR 16N115W AND THE OTHER NEAR 12N130W. SATELLITE IMAGERY SHOWS 
THE MONSOON TROUGH BREAKING DOWN...WITH A WESTERN PORTION THAT 
INCLUDES THE EMBEDDED LOWS LIFTING NORTHWARD WHILE AN EASTERN 
PORTION IS REFORMING ROUGHLY ALONG 09N E OF 110W. THE BREAKDOWN 
OF THE MONSOON TROUGH WILL CONTINUE OVER THE NEXT COUPLE DAYS. 
THE EASTERN LOW IS THE LARGER OF THE TWO...BUT THE WESTERN LOW 
IS THE STRONGER FEATURE. THE EARLIER ASCAT PASS DEPICTED 30 KT 
WINDS IN THE SOUTH SEMICIRCLE AND 25 KT IN THE N SEMICIRCLE OF 
THE WESTERNMOST LOW. MODEL GUIDANCE SHOWS NEITHER LOW IS LIKELY 
TO INTENSIFY SIGNIFICANTLY DURING THE NEXT 12-24 HOURS...AND 
BOTH LOWS HAVE A LOW CHANCE OF BECOMING A TROPICAL CYCLONE.
