2205 UTC SAT JUN 14 2008

TROPICAL WEATHER DISCUSSION FOR THE EASTERN PACIFIC OCEAN
FROM THE EQUATOR TO 32N...EAST OF 140W. 

BASED ON 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2100 UTC.

...ITCZ...

INTERTROPICAL CONVERGENCE ZONE (ITCZ) IS CENTERED ALONG 07N77W 
06N85W 08N98W 05N111W 06N124W 06N140W. SCATTERED MODERATE STRONG 
CONVECTION IS N OF THE ITCZ WITHIN 120 NM W OF A SURFACE TROUGH 
THAT EXTENDS FROM 03N103W TO 11N102W WITH CLUSTERS INLAND OVER W 
PANAMA AND COSTA RICA FROM 80W TO 84W. SCATTERED MODERATE TO 
ISOLATED STRONG CONVECTION IS WITHIN 120 NM S OF THE ITCZ E OF 
83W TO INLAND OVER COLOMBIA. CLUSTERS OF SIMILAR CONVECTION ARE 
WITHIN 150 NM EITHER SIDE OF THE ITCZ BETWEEN 86W TO 109W WHICH 
EXHIBITS SOME MID LEVEL ROTATION. 

...DISCUSSION...
E OF 110W...
FRESH TO STRONG EASTERLY WINDS ACROSS THE CARIBBEAN ARE 
GENERATING GAP WINDS OF UP TO 20 KNOTS IN THE GULF OF PAPAGAYO 
REGION. UPPER RIDGE ANCHORED OVER COSTA RICA WITH THE RIDGE AXIS 
EXTENDING NW TO 14N110W IS PROVIDING DIFFLUENCE ALOFT TO ENHANCE 
THE CONVECTION WITHIN THE ITCZ AND THE SURFACE TROUGH. AN UPPER 
HIGH IS OVER N/CENTRAL WITH THE RIDGE EXTENDING S INTO THE E 
PACIFIC REGION NEAR THE ABOVE SURFACE TROUGH ENHANCING THE 
CONVECTION. 

W OF 110W...
AN UPPER RIDGE ANCHORED SW OF THE AREA COVERS THE AREA S OF 15N 
W OF 120W PROVIDING DIFFLUENCE ALOFT TO ENHANCE THE CLOUDS AND 
POSSIBLE SHOWERS WITHIN 180 NM OF THE ITCZ BETWEEN 120W AND 
140W. A SURFACE TROUGH IS EMBEDDED WITHIN THIS AREA AND THE ITCZ 
FROM 10N126W TO 05N128W BUT IS RAPIDLY LOSING ITS IDENTITY. A 
SURFACE RIDGE EXTENDS FROM A 1034 MB HIGH NW OF THE REGION NEAR 
42N144W WITH THE RIDGE AXIS EXTENDING SE TO 26N127W. FRESH TO 
STRONG WINDS ARE N OF THE REGION CONTINUE TO PUSH SWELLS S 
OVER THE NW PORTION OF THE REGION. 

FRESH TO STRONG WINDS ARE OVER THE SE PORTION OF THE REGION TO  
S OF THE EQUATOR ALSO PRODUCING LARGE SWELLS.
