TROPICAL WEATHER DISCUSSION    
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
2205 UTC WED NOV 08 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 
2100 UTC.

...SPECIAL FEATURE...
TROPICAL DEPRESSION NINETEEN E NEAR 14.3N 104.3W 1005 MB AT 2100 
UTC NOV 08 MOVING N-NW OR 335 DEG AT 6 KT.  MAXIMUM SUSTAINED 
WIND 30 GUSTS 40 KT.  SEE LATEST NHC FORECAST/ADVISORY UNDER 
AWIPS/WMO HEADERS MIATCMEP4/WTPZ24 KNHC FOR MORE DETAILS. 
NUMEROUS STRONG CONVECTION WITHIN 120 NM OF DEPRESSION CENTER.

...TROPICAL WAVES...
NONE.

...ITCZ...
ITCZ AXIS ALONG 9N79W  8N91W  13N105W  6N132W 6N140W. 
ISOLATED MODERATE WITHIN 90 NM OF AXIS E OF 98W. 

...DISCUSSION...
WEIRD LAID BACK UPPER LEVEL TROUGH RUNS E-W ALONG 26N WITH 
CYCLONIC VORTEX AT 26N124W.  VERY DRY AIR MASS N OF 22N PREVENTS 
ANY CONVECTION DEVELOPMENT.  SECOND CYCLONIC VORTEX AT 16N143W 
COMBINES WITH BROAD MID/UPPER LEVEL RIDGE TO ADVECT TROPICAL 
MOISTURE NWD W OF 129N S OF 22N.  LARGE ANTICYCLONIC CIRCULATION
CENTERED AT 11N98W DOMINATES FLOW S OF 22N E OF 124W ALLOWING 
TROPICAL MOISTURE FROM CARIBBEAN BASIN TO CROSS INTO E PAC AT 
ITCZ LEVEL.  OTHERWISE AREA REMAINS PRETTY DRY AND LACKING 
UPLIFTING MECHANISM TO ENHANCE ITCZ CONVECTION.  ONLY FEATURES 
NOTED ARE TROPICAL DEPRESSION DISCUSSED ABOVE AND WEAK LOW PRES 
SYSTEM NEAR 10N113W BEING MONITORED FOR DEVELOPMENT...BUT ITS 
CLOSENESS TO THE DEPRESSION CURTAILS ITS POSSIBILITIES. 

AT THE SURFACE...HIGH PRES CENTER 1032 MB WELL N OF AREA HAS 
RIDGE EXTEND 15N115W KEEPING MODERATE TRADES N OF 10N W OF 120W.
