NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
0405 UTC SAT JUN 10 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 0000 UTC SURFACE ANALYSIS AND SATELLITE IMAGERY THROUGH 
UTC.
 
...TROPICAL WAVES...
TROPICAL WAVE N OF 3N ALONG 82W IS MOVING W AT 10 KT. SCATTERED 
MODERATE ISOLATED STRONG CONVECTION LIES ALONG THE WAVE AXIS AND 
EXTENDS NORTHWARD TO THE COASTS OF PANAMA AND COSTA RICA BETWEEN 
81W AND 86W. ACTIVITY HAS NOT CHANGED MUCH DURING THE PAST 12 
HOURS. THERE IS NO ORGANIZATION AT THIS TIME.
 
TROPICAL WAVE N OF 3N ALONG 96W HAS BEEN MOVING W AT 10 KT. 
THERE IS AN AREA OF SCATTERED MODERATE ISOLATED STRONG  
CONVECTION CENTERED NEAR 13N93W IN ASSOCIATION WITH A 1010 MB 
LOW PRESSURE. SATELLITE IMAGERY INDICATES WELL DEFINED CYCLONIC 
TURNING IN THE LOW AND MID LEVEL CLOUDS. 

TROPICAL WAVE ALONG 115W FROM 5N TO 14N IS MOVING W AT 10 KT. 
ONLY WIDELY SCATTERED MODERATE CONVECTION IS NOTED NEAR THE 
INTERSECTION OF THE WAVE AND THE ITCZ.

..ITCZ...
THE INTERTROPICAL CONVERGENCE ZONE AXIS ALONG 10N86W 12N90W 
9N110W 8N120W 9N140W. SCATTERED MODERATE ISOLATED STRONG WITHIN 
120 NM OF THE AXIS BETWEEN 95W AND 102W...AND W OF 136W...AND N 
OF 4N TO THE COAST OF PANAMA AND COSTA RICA BETWEEN 81W AND 86W. 

...DISCUSSION...

W OF 110W...
SHARP UPPER LEVEL TROUGH EXTENDS FROM SRN CALIFORNIA SWWD 
THROUGH 30N124W 22N133W TO 16N140W AND WAS ACCOMPANIED BY STRONG 
UPPER LEVEL SUBSIDENCE AT THE BASE OF THE TROUGH AND E OF THE 
TROUGH AXIS TO 110W INCLUDING THE BAJA PENINSULA AND NW MEXICO. 
NARROW UPPER LEVEL RIDGE AXIS WAS INDICATED TO THE W OF THE 
TROUGH AXIS OVER THE FAR NW CORNER OF THE DISCUSSION AREA. THE 
RIDGE WAS MOVING SEWD AT 10-15 KT. MODERATE ELY FLOW WAS NOTED 
OVER THE TROPICS S OF 18N AND E OF 120W. THIS FLOW WAS ADVECTING 
SOME MID TO UPPER LEVEL MOISTURE WWD TO ALONG 120W. AT THE 
SURFACE...RIDGE OF HIGH PRESSURE DOMINATED THE AREA N OF 12N AND 
W OF 110W. 

E OF 110W...
FAIRLY LARGE MID TO UPPER LEVEL ANTICYCLONE NEAR 22N105W 
DOMINATED THE FLOW OVER MEXICO AND THE E PACIFIC BETWEEN 90W AND 
110W. MODERATE NE FLOW ALOFT WAS ADVECTING COPIOUS AMOUNTS OF 
MID TO UPPER LEVEL MOISTURE WWD ACROSS THE TROPICAL E PACIFIC W 
OF 80W. A SHARP DELINEATION EXISTED BETWEEN THIS AREA OF DEEP 
MOISTURE AND AN AREA OF STRONG UPPER LEVEL SUBSIDENCE OVER THE 
GULF OF MEXICO...BAY OF CAMPECHE AND THE ISTHMUS OF TEHUANTEPEC.
THE AREA OF SUBSIDENCE WAS PRESSING SWD ACROSS THE AREA. AT
THE SURFACE...1008 MB LOW NEAR 15N101W WAS DRIFTING WWD AND WAS 
ACCOMPANIED BY A PATCH OF SCATTERED MODERATE CONVECTION. 
ELSEWHERE CROSS EQUATORIAL SLY WINDS CONTINUE TO ACCELERATE 
TOWARD LOWER PRESSURE S OF 12N BETWEEN 90W AND 110W.
