0845 UTC.

...TROPICAL WAVES...
TROPICAL WAVE ALONG 94W/95W N OF 5N MOVING W 15 KT BASED ON A 24 
HOUR MOTION. ONLY LOCALLY SCATTERED MODERATE CONVECTION IS 
INDICATED WITHIN 5 DEGREES W OF AXIS ALONG THE ITCZ. 

TROPICAL WAVE ALONG 105W FROM 5N TO 15N MOVING W 10 KT BASED ON 
A 24 HOUR MOTION. A WEAK LOW PRES CENTER NEAR 12N108W MAY BE 
ASSOCIATED WITH THIS WAVE. SCATTERED MODERATE TO STRONG 
CONVECTION IS ASSOCIATED MORE WITH THE LOW PRESSURE AREA THAN 
THE WAVE ITSELF. MODERATE NE WINDS ALOFT ARE PRECLUDING ANY 
DEVELOPMENT OF THIS FEATURE AT THIS TIME. 

TROPICAL WAVE ALONG 124W FROM 6N TO 15N MOVING W 15 KT BASED ON 
A 24 HOUR MOTION. ITCZ IS PULLED NWD ALONG AND E AST OF THE WAVE 
AXIS. NO SIGNIFICANT CONVECTION NOTED WITH THIS WAVE.
 
TROPICAL WAVE ALONG 135W FROM 5N TO 14N MOVING W 15 KT BASED ON 
A 24 HOUR MOTION. WIDELY SCATTERED MODERATE CONVECTION ALONG THE 
ITCZ W OF 133W. CIRRUS CLOUDS INDICATE 40 KT WLY WINDS AT 200 MB

...DISCUSSION...

NARROW UPPER LEVEL TROUGH EXTENDS FROM 32N128W SWD TO A 5-7 DEG 
WIDE CYCLONIC CIRCULATION NEAR 18.5N127W. THE CYCLONIC 
CIRCULATION IS MOVING NWWD 10 KT. MODERATE TO STRONG SUBSIDENCE

E OF 130W. FURTHER E...A RATHER LARGE ELONGATED RIDGE AXIS WITH 
EMBEDDED ANTICYCLONES NEAR 29N109W AND 21N105W. MODERATE 
EASTERLY FLOW S OF THE RIDGE IS ADVECTING MID TO UPPER LEVEL 
MOISTURE WWD OVER THE DEEP TROPICS BETWEEN 95W AND 120W. LIGHT 
TO MODERATE NLY FLOW PREVAILS ELSEWHERE OVER THE TROPICAL 
PACIFIC E OF 95W. AT THE SURFACE....RIDGE OF HIGH PRESSURE 
DOMINATED THE AREA N OF 12N W OF 110W.
