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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
0215 UTC.

...INTERTROPICAL CONVERGENCE ZONE/MONSOON TROUGH...           
THE MONSOON TROUGH IS ALONG 09N79W TO 10N86W TO 13N96W RESUMING 
NEAR 11N102W TO 10N113W TO 10N126W. THE INTERTROPICAL 
CONVERGENCE ZONE AXIS EXTENDS FROM 10N126W TO 06N140W. WIDELY 
SCATTERED MODERATE AND ISOLATED STRONG CONVECTION IS FROM 04N TO 
10N BETWEEN 78W AND 85W...AND FROM 04N TO 15N BETWEEN 95W AND 
102W. ISOLATED MODERATE CONVECTION IS FROM 07N TO 12N BETWEEN 
108W AND 131W.

...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 24N119W. 
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 1032 MB HIGH CENTERED N-NW OF THE AREA 
NEAR 39N144W.

FARTHER EAST...ANOTHER UPPER LEVEL ANTICYCLONIC CIRCULATION IS 
NOTED ON WATER VAPOR IMAGERY NEAR 15N100W 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 03N 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.
