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 1200 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
1500 UTC.

...TROPICAL WAVES...

TROPICAL WAVE ALONG 90W IS MOVING W 10 TO 15 KT. THIS FEATURE IS 
VERY WEAK AND BARELY IDENTIFIABLE ON VISIBLE SATELLITE IMAGERY.

TROPICAL WAVE ALONG 106W IS MOVING W ABOUT 15 KT. TWO DISTINCT 
AREAS OF ACTIVE CONVECTION ARE ASSOCIATED WITH THIS FEATURE. THE 
FIRST IS WITHIN 3 TO 4 DEGREES EITHER SIDE OF THE AXIS FROM 8N 
TO 11N AND THE SECOND WITHIN 3 TO 4 DEGREES EITHER SIDE OF THE 
AXIS FROM 14N TO 17N.

TROPICAL WAVE ALONG 123W IS MOVING W ABOUT 15 KT. SCATTERED 
MODERATE TO STRONG CONVECTION...MAINLY ASSOCIATED WITH THE 
ITCZ...IS LOCATED 3 TO 4 DEGREES EITHER SIDE OF THE AXIS FROM 8N 
TO 12N.

TROPICAL WAVE ALONG 137W IS MOVING W 10 TO 15 KT. THIS WAVE IS 
VERY WEAK AND ONLY ISOLATED CONVECTION IS ASSOCIATED WITH IT.

...ITCZ...

A MIDDLE/UPPER LEVEL RIDGE OVER THE NW PART OF THE DISCUSSION 
AREA HAS ITS AXIS ALONG 135W FROM 15N TO 32N WITH ANTICYCLONIC 
FLOW NOTED ABOUT 5 DEGREES EITHER SIDE OF THE AXIS. MOVING 
DOWNSTREAM A MIDDLE/UPPER LEVEL TROUGH HAS ITS AXIS ALONG 126W N 
OF 18N. THIS FEATURE IS NEARLY STATIONARY WITH CYCLONIC FLOW 
NOTED 6 TO 7 DEGREES EITHER SIDE OF THE AXIS. A WEAK CYCLONIC 
CIRCULATION IS DEVELOPING ALONG THE TROUGH AXIS NEAR 24N125W. 
ALONG THE W COAST OF MEXICO AND CONTINUING OFFSHORE ABOUT 300 
MILES WEAK RIDGING ALOFT IS NOTED IN WATER VAPOR IMAGERY.

S OF 15N...
LIGHT TO OCCASIONAL MODERATE FLOW ALOFT COVERS THE TROPICS WITH
