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 
0315 UTC.

...TROPICAL WAVES...
TROPICAL WAVE ALONG 92.5W N OF 5N MOVING W 12 KT. SCATTERED 
MODERATE ISOLATED STRONG CONVECTION WITHIN 90 NM OF AXIS N OF 6N 
TO THE COAST OF CENTRAL AMERICA WITH CYCLONIC TURNING NOTED NEAR 
13N94W AT THE MOMENT.

TROPICAL WAVE ALONG 103W FROM 5N TO 15N MOVING W 12 KT.  
SCATTERED MODERATE ISOLATED STRONG CONVECTION WITHIN 90 NM OF 
WAVE AXIS BUT REMAINS WITHIN THE ITCZ.

TROPICAL WAVE ALONG 122W FROM 4N TO 14N MOVING W AT 10 KT. A 
CLUSTER OF TSTMS NEAR 6N122W SHOWS SOME SIGNS OF CYCLONIC 
ROTATION BUT THE AREA IS DEEPLY EMBEDDED IN THE ITCZ. 

TROPICAL WAVE ALONG 132W FROM 5N TO 17N MOVING W 10 KT. 
BROAD CYCLONIC TURNING NOTED WITH ONLY MINOR ENHANCEMENT OF ITCZ 
CONVECTION AT 8N DURING THE PAST FEW HOURS.

..ITCZ...
INTERTROPICAL CONVERGENCE ZONE ALONG 10N. SCATTERED MODERATE 
ISOLATED STRONG WITHIN 240 NM EITHER SIDE OF LINE 11N83W 8N130W.

...DISCUSSION...
AN UPPER CYCLONE CUT OFF AT 29N142W WITH A TROUGH S TO A BASE 
NEAR 10N143W WITH THIS SYSTEM EXPECTED TO MOVE LITTLE UNTIL 
BECOMING ABSORBED IN ABOUT 36 HOURS BY A LARGER SHORTWAVE TROUGH 
CURRENTLY W OF THE AREA ALONG 148W. AN UPPER ANTICYCLONE IS 
QUASI-STATIONARY NEAR 17N122W. A RIDGE AXIS EXTENDS SW TO NEAR 
9N134W ENHANCING ITCZ CONVECTION BETWEEN 123W AND 134W. THE 
RESULTANT DEBRIS MOISTURE SPREADS N ALONG THE W PERIPHERY OF THE 
ANTICYCLONE TO NEAR 22N125W WHERE IT EVAPORATES. A RIDGE ALSO
EXTENDS N TO BEYOND 32N127W MERGING WITH A LARGE RIDGE 
DOMINATING THE W COAST OF N AMERICA. THE ENVELOPE OF 
ANTICYCLONIC FLOW IS N OF THE ITCZ SQUEEZED BETWEEN 132W AND 
119W. AN UPPER CYCLONE IS NOTED NEAR 33N119W WITH AN UPPER 
TROUGH EXTENDING S ALONG 27N115W 20N113W 13N115W. AT THE SURFACE 
A HIGH PRES IS NEAR 25N125W 1019 MB AND IS EXPECTED TO WEAKEN AS 
A STRONGER RIDGE BUILDS FROM THE NW BY 24 HOURS. A WEAK TROUGH 
EXTENDS SW ALONG 32N127W TO 28N132W. BROKEN TO OVERCAST 
STRATOCUMULUS IS OBSERVED NW OF LINE 17N140W 25N118W.
  
A TROPICAL UPPER TROUGH... TUTT...EXTENDS ACROSS THE SW N ATLC 
ALONG 30N55W ACROSS THE NW BAHAMAS AND THE CENTRAL GULF OF 
MEXICO TO 22N99W. JUST TO S...AN UPPER ANTICYCLONE IS NEAR 
16N100W WITH ITS ENVELOPE OF ANTICYCLONIC FLOW ZONAL ALONG 22N 
JUST TO THE S OF THE UPPER TROUGH THEN SPILLING SE OVER THE 
CENTRAL CARIBBEAN AND RETURNING W ALONG THE TROPICAL E PAC 
WATERS N OF THE EQUATOR E OF 114W...WITH UPPER DIFFLUENCE 
ENHANCING CONVECTION ALONG THE E PAC ITCZ TO THE E OF 112W.
