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.

...TROPICAL WAVES...                                            
A TROPICAL WAVE WITH AXIS APPROACHING 100W IS MOVING WEST AROUND 
10 KT. THERE IS LIMITED CONVECTION ASSOCIATED TO THIS WAVE. 

A TROPICAL WAVE IS JUST ENTERING THE FAR EASTERN WATERS. 
SCATTERED MODERATE ISOLATED STRONG CONVECTION IS NOTED FROM 10N 
TO 12N E OF 90W ASSOCIATED TO THE WAVE. AS IS TYPICAL WHEN 
TROPICAL WAVES MOVE ACROSS CENTRAL AMERICA INTO THE EASTERN 
NORTH PACIFIC...GAP WINDS ARE FUNNELING THROUGH THE GULF OF 
PAPAGAYO WITH RECENT SCATTEROMETER PASS DEPICTING WINDS IN THE 
20 TO 25 KT RANGE. 
 
...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...              
THE MONSOON TROUGH EXTENDS FROM 09N84W TO 09N104W WHERE LOW 
LEVEL WINDS SUGGEST A TRANSITION TO ITCZ WHICH EXTENDS TO BEYOND 
04N140W. ISOLATED MODERATE CONVECTION WAS NOTED WITHIN 90 NM OF 
ITCZ BETWEEN 124W AND 130W.

...DISCUSSION...                                                 
THE REMNANT LOW OF CRISTINA CONTINUES TO SPIN WITH LATEST 
SCATTEROMETER PASS CAPTURING THE CIRCULATION CENTER NEAR 
23N117W. THE CIRCULATION WILL CONTINUE TO SPIN DOWN OVER THE 
NEXT COUPLE OF DAYS AND IS EXPECTED TO DISSIPATE BY WED NIGHT. 

HIGH PRESSURE OF 1031 MB CENTERED WELL NW OF THE AREA NEAR 
38N148W EXTENDS A RIDGE SE TO NEAR 29N129W. THE PRESSURE 
GRADIENT BETWEEN THE RIDGE AND LOWER PRESSURE IN THE VICINITY OF 
THE ITCZ IS SUPPORTING MAINLY GENTLE TO MODERATE WINDS BASED ON 
THE LATEST SCATTEROMETER DATA. A SMALL AREA OF 8 FT SEAS PERSIST 
FROM 08N TO 10N W OF 137W WITH RESIDUAL SE SWELL. THIS AREA OF 
SEAS WILL SUBSIDE BELOW 8 FT BY THIS EVENING.

SW SWELL ASSOCIATED WITH A FRONT IN THE SOUTHERN HEMISPHERE WILL 
APPROACH THE EQUATOR BETWEEN 110W AND 125W THU MORNING. COMBINED 
SEAS TO 8 FT WILL PUSH NORTH OF THE EQUATOR AND COVER THE AREA 
ROUGHLY S OF 02N BETWEEN 110W AND 125W BY THU NIGHT.
