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 78W N OF 8N IS MOVING W AT AN ESTIMATED 15 
KT. THE WAVE MAY BE ENHANCING SCATTERED MODERATE CONVECTION 
OVER W PANAMA. 

TROPICAL WAVE ALONG 91W FROM 4N TO 12N IS MOVING W AT AN 
ESTIMATED 15 KT. THE WAVE IS WEAK AND DIFFICULT TO LOCATE ON THE 
LATEST SATELLITE IMAGERY.

TROPICAL WAVE ALONG 110W FROM 5N TO 16N IS MOVING W AT AN 
ESTIMATED 12 KT. THE WAVE IS ILL-DEFINED BUT IS ENHANCING 
CONVECTION EITHER SIDE OF THE AXIS FROM 8N TO 12N.

TROPICAL WAVE ALONG 133W FROM 6N TO 14N IS MOVING W AT AN 
ESTIMATED 15 KT. THE WAVE IS CURRENTLY DEVOID OF ANY SIGNIFICANT 
CONVECTION.

INTERTROPICAL CONVERGENCE ZONE...AXIS 9N78W 9N100W 9N117W 
10N130W 8N140W. SCATTERED MODERATE ISOLATED STRONG CONVECTION IS 
LOCATED WITHIN A 60 NM RADIUS OF 5N85W...WITHIN A 60 NM RADIUS 
OF 7.5N91.5W...WITHIN 60 NM EITHER SIDE OF A 6N99W 12N104W 
10N110W LINE...AND WITHIN A 45 NM RADIUS OF 9N120W.

...DISCUSSION...

A MIDDLE/UPPER LEVEL TROUGH HAS BEEN ANCHORED OFF THE W COAST OF 
THE UNTIED STATES FOR SEVERAL DAYS WITH ITS SOUTHERN EXTENSION 
COVERING THE NW PART OF THE DISCUSSION AREA ROUGHLY N OF 25N W 
OF 125W. A JET LOCATED THROUGH 21N140W TO 30N125W HAS WEAKENED 
OVER THE PAST 24 TO 36 HOURS BUT IS STILL EASILY IDENTIFIABLE ON 
GOES-11 WATER VAPOR IMAGERY. A FAIRLY STRONG WESTERLY JET IS 
ENTERING THE AREA AT 20N140W. 

MOVING DOWNSTREAM THE NEXT FEATURE OF NOTE IS A RIDGE ALOFT WITH 
ITS AXIS EXTENDING FROM 30N122W TO 15N128W. AN ELONGATED MIDDLE/ 
UPPER LEVEL CYCLONIC CIRCULATION IS CENTERED OVER SOUTHERN BAJA 
CALIFORNIA NEAR 25N112W AND IS NEARLY STATIONARY. A TROUGH AXIS 
EXTENDS FROM THE CIRCULATION CENTER TO NEAR 12N118W. THIS 
FEATURE IS AIDING AN AREA OF LAYERED CLOUDS WITH SCATTERED 
SHOWERS AND A FEW THUNDERSTORMS LOCATED N OF 13N INTO MEXICO 
BETWEEN 102W AND 107W. RIDGING ALOFT COVERS THE DEEP TROPICS 
BETWEEN 90W AND 102W. A CYCLONIC CIRCULATION APPEARS TO BE 
FORMING IN THE VICINITY OF 12N88W.
