TROPICAL WEATHER DISCUSSION
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2205 UTC THU JUN 01 2006

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 1800 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
2130 UTC.

...TROPICAL WAVES...
TROPICAL WAVE ALONG 82W MOVING W 10 KT. CLUSTERS OF MODERATE TO 
STRONG CONVECTION NEAR WAVE AXIS N OF 5N TO THE GULF OF PANAMA 
BETWEEN 79W AND 85W. 

TROPICAL WAVE ALONG 108W FROM 3N TO 12N MOVING W 10 KT. 
SCATTERED MODERATE CONVECTION WITHIN 120 NM W OF WAVE AXIS FROM 
7N TO 10N SHOW NO SIGNS OF ORGANIZATION. SCATTERED MODERATE TO 
STRONG CONVECTION IS INDICATED WELL E OF THE WAVE AXIS WITHIN 
90-120 NM OF THE ITCZ GENERALLY BETWEEN 98W AND 106W.

..ITCZ...
ITCZ AXIS ALONG....7N81W 13N98W 8N120W 5N140W.
SCATTERED MODERATE TO STRONG N OF 5N BETWEEN 79W AND 85W 
INCLUDING THE GULF OF PANAMA...AND 90-120 NM OF THE AXIS BETWEEN 
98W AND 106W. SCATTERED MODERATE ISOLATED STRONG WITHIN 90-120 
NM OF THE AXIS W OF 132W...AND BETWEEN 110W AND 117W.

...DISCUSSION...
UPPER LEVEL SHEAR AXIS EXTENDS 32N120W SWD THROUGH 22N126W TO 
19N140W AND WAS ACCOMPANIED BY STRONG SUBSIDENCE WITHIN 60-90 NM 
EITHER SIDE OF THE AXIS. WELL DEFINED ANTICYCLONE NEAR 23N141W
DOMINATED THE AREA N AND W OF THE SHEAR AXIS. BROAD ANTICYCLONIC 
FLOW COVERED THE DEEP TROPICS S OF 19N WITH A LARGE ANTICYCLONE 
CENTERED NEAR 14N104W WITH ANOTHER WEAKER CENTER NEAR 12N131W. 
ANTICYCLONE UPPER LEVEL FLOW BECAME DIFFLUENT TIN NATURE AND WAS 
AIDING IN MAINTAINING STRONG CONVECTION ALONG THE ITCZ BETWEEN 
98W AND 106W IN ASSOCIATION WITH LOW PRES CENTERED NEAR 11N102W 
1008 MB...AND ALSO N OF 5N TO THE COAST OF PANAMA BETWEEN 79W 
AND 85W. 

AT THE SURFACE...WEAKENING HIGH PRES CENTER NEAR 27N132W 1022 MB 
WITH A RIDGE COVERING THE AREA N OF ITCZ W OF 110W. THIS FEATURE 
IS PRODUCING TRADE WINDS OF 20 KT BETWEEN FROM 7N AND 15N W OF 
125W.
