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 
0830 UTC.

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

THE MONSOON TROUGH AXIS EXTENDS FROM 07N78W TO A 1007 MB LOW 
PRES NEAR 10N100W THEN ON TO 10N120W. THE ITCZ EXTENDS FROM 
10N100W TO BEYOND 05N140W. SCATTERED MODERATE CONVECTION 
IS NOTED WITHIN 120 NM EITHER SIDE OF TROUGH AXIS E OF 90W. 

...DISCUSSION...     

A 1032 MB HIGH PRESSURE LOCATED WELL NORTH OF THE DISCUSSION 
AREA EXTENDS A RIDGE SOUTH-SOUTHEASTWARD INTO THE REGION THROUGH 
30N130W TO THE COAST OF BAJA CALIFORNIA NORTE NEAR 27N115W. THE 
PRESSURE GRADIENT BETWEEN THIS SURFACE RIDGE AND THE LOWER 
PRESSURE ALONG THE ITCZ IS PRODUCING MODERATE TO FRESH BREEZE 
TRADE WINDS ALONG THE SOUTHERN PERIPHERY OF THE RIDGE. THESE 
SHOULD CONTINUE FOR THE NEXT SEVERAL DAYS...INCREASING SLIGHT BY 
SATURDAY TO 20 TO 25 KT. LOOKING AHEAD...THE WINDS WILL DIMINISH 
THROUGH SATURDAY BUT WILL BE FOLLOWED BY NORTHERLY 10 SECOND 
PERIOD SWELL TO 9 FT PUSHING SOUTH OF 30N AND COVERING THE AREA 
N OF 26N BETWEEN 120W AND 135W.

AN ASCAT SATELLITE PASS FROM 0348 UTC INDICATED A WEAK 
CIRCULATION CENTERED NEAR 12N101W. THIS WAS SAMPLED BY AN 
EARLIER ASCAT PASS YESTERDAY AND APPEARS TO HAVE WEAKENED 
CONSIDERABLY SINCE THAT TIME. GLOBAL MODELS SHOW IT 
MOVING LITTLE AND DISSIPATING THROUGH THE NEXT 48 TO 72 HOURS.

A 0530 UTC ASCAT SATELLITE PASS INDICATED A SURFACE TROUGH ALONG 
THE ITCZ FROM 06N TO 12N BETWEEN 125W AND 130W. THIS TROUGH 
STACKS WELL WITH A LOWER TO MID LEVEL TROUGH NOTED IN GOES 
DERIVED HIGH DENSITY WIND DATA AND IS ASSOCIATED WITH A BROAD 
UPPER TROUGH TO THE NW OF THE AREA. NO SIGNIFICANT CONVECTION OR 
WINDS ARE NOTED WITH THIS FEATURE.

WITH THE DEMISE OF BORIS...NO SIGNIFICANT TROPICAL DEVELOPMENT 
APPEARS LIKELY OVER THE NEXT SEVERAL DAYS.

THE FORECAST WIND GRIDS...THROUGH 48 HOURS...ARE A BLEND OF THE 
00Z GFS ALONG WITH THE PREVIOUS OFFICIAL FORECAST. THE WAVE 
GRIDS THROUGH 48 HOURS ARE A BLEND OF THE 00Z WAVE WATCH III 
ALONG WITH THE PREVIOUS OFFICIAL FORECAST.
