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 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2100 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...           
THE MONSOON TROUGH IS ALONG 07N78W TO 13N98W TO 1007 MB LOW PRES 
NEAR 12N100W TO 09N113W TO 11N125W TO 1009 MB LOW PRES NEAR 
11N128W. THE INTERTROPICAL CONVERGENCE ZONE AXIS EXTENDS FROM 
1009 MB LOW PRES NEAR 11N128W TO 05N140W. SCATTERED MODERATE 
CONVECTION IS FROM 04N TO 07N BETWEEN 78W AND 83W...AND FROM 07N 
TO 09N BETWEEN 93W AND 98W. ISOLATED MODERATE CONVECTION IS 
ELSEWHERE FROM 03N TO 16N BETWEEN 89W AND 103W. WIDELY SCATTERED 
MODERATE CONVECTION IS FROM 07N TO 12N BETWEEN 106W AND 114W... 
AND FROM 08N TO 11N BETWEEN 116W AND 125W.

...DISCUSSION...                                                
FAIRLY TRANQUIL CONDITIONS EXIST NORTH OF THE ITCZ REGION WEST 
OF 106W AS WATER VAPOR IMAGERY SHOWS A FAIRLY BROAD MIDDLE TO 
UPPER LEVEL ANTICYCLONIC CIRCULATION CENTERED NEAR 23N120W. 
OVERALL...THE UPPER LEVEL RIDGING REMAINS IN VERY DRY AND STABLE 
AIR PROVIDING GENERAL STABILITY TO CONDITIONS AT THE SURFACE 
WITH TRADES REMAINING 20 KT OR LESS AT THIS TIME. MODERATE TO 
FRESH TRADES ARE EXPECTED TO PERSIST ACROSS THE NORTHERN 
FORECAST WATERS THROUGH THE 48 HOUR PERIOD WITH ONLY A SMALL 
AREA OF NW WINDS OCCURRING IN THE RANGE OF 20 TO 25 KT OFF THE 
COAST OF CENTRAL BAJA CALIFORNIA DUE TO A STRENGTHENED PRESSURE 
GRADIENT THAT IS FORECAST TO RELAX BY SATURDAY. THE OTHER AREA 
OF SIGNIFICANT MARINE CONDITIONS IS NORTHERLY SWELL ASSOCIATED 
WITH STRONG WINDS OFF THE NORTHERN CALIFORNIA COAST REMAINING N 
OF 27N BETWEEN 122W AND 134W ON SATURDAY BUILDING SEAS TO 9 FT. 
OTHERWISE...A SURFACE RIDGE IS EXPECTED TO MAINTAIN HOLD OVER 
THE WATERS ANCHORED BY A 1030 MB HIGH CENTERED N-NW OF THE AREA 
NEAR 40N140W.

FARTHER EAST...ANOTHER UPPER LEVEL ANTICYCLONIC CIRCULATION IS 
NOTED ON WATER VAPOR IMAGERY NEAR 15N99W THAT INVOLVES ITSELF 
WITH MORE MOISTURE THAN ITS COUNTERPART TO THE WEST MENTIONED 
ABOVE. IN GENERAL...CONDITIONS ARE MOSTLY TRANQUIL ACROSS THE 
AREA E OF 106W AS WELL...HOWEVER A MORE DIFFLUENT ENVIRONMENT IS 
IN PLACE GENERATING AREAS OF ISOLATED AND SCATTERED CONVECTION N 
OF 02N E OF 106W THAT INCLUDE THE MONSOON TROUGH REGION AND 
AREAS ALONG THE SOUTHERN MEXICO COASTLINE. OTHERWISE...NO 
SIGNIFICANT AREAS OF TROPICAL DEVELOPMENT APPEAR LIKELY DURING 
THE NEXT SEVERAL DAYS. 

FINALLY...CROSS-EQUATORIAL SW SWELL HAS MOVED INTO THE SW CORNER 
OF THE FORECAST AREA WITH PERIODS IN THE 18-21 SECOND RANGE. THE 
LEADING EDGE OF THIS SWELL WILL REACH THE GALAPAGOS ISLANDS 
SATURDAY MORNING AND MUCH OF THE MAINLAND COASTLINE FROM BAJA 
NORTE SOUTHWARD BY EARLY SUNDAY.
