 HURRICANE ILEANA DISCUSSION NUMBER  14
 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP102006
 200 PM PDT THU AUG 24 2006
  
 THE SATELLITE PRESENTATION SUGGESTS THAT ILEANA HAS MADE A BIT OF A
 COMEBACK TODAY...AS CLOUD TOPS HAVE COOLED NEAR THE CENTER. THE
 CURRENT INTENSITY IS HELD AT 85 KT BASED ON A BLEND OF CI AND T
 NUMBERS FROM TAFB AND SAB AND AODT NUMBERS THAT HAVE INCREASED DUE
 TO THE IMPROVED SATELLITE REPRESENTATION. THE INTENSITY FORECAST IS
 HELD A LITTLE HIGHER THAN THE PREVIOUS ADVISORY FOR THE FIRST 12
 HOURS DUE TO THE...PRESUMABLY TEMPORARY ...INCREASE IN DEEP
 CONVECTION. HOWEVER...STEADY WEAKENING IS FORECAST BEYOND 24 HOURS
 AS THE CYCLONE WILL BE CROSSING THE 26C ISOTHERM. ILEANA SHOULD
 BECOME A REMNANT LOW BY DAY 4 WITH DISSIPATION SOON TO FOLLOW.
 
 THE INITIAL MOTION HAS CONTINUED TO SLOW AND IS NOW 300/7. THE
 FORECAST REASONING REMAINS UNCHANGED...WITH ILEANA FEELING THE
 EFFECTS OF THE BREAK IN THE MID-LEVEL RIDGE WHILE IT REMAINS A DEEP
 SYSTEM AND THEN TURNING WESTWARD WITH THE LOW-LEVEL FLOW AS THE
 CYCLONE WEAKENS. THE FORECAST IS CLOSE TO THE PREVIOUS TRACK AND
 THE DYNAMICAL MODEL CONSENSUS...CONU...THROUGH 24 HOURS AND
 REFLECTS A BLEND OF THE PREVIOUS FORECAST AND CONU FOR DAY 2. BY
 DAY 3 A MOTION SOUTH OF DUE WEST WAS INTRODUCED...SLIGHTLY SOUTH OF
 THE PREVIOUS FORECAST AND REFLECTING THE SOUTHWARD TRENDS OF THE
 CONU AND GUNA CONSENSUS TRACKS...THE GFDL AND SHALLOW BAM.
 
 THE 34-KT WIND RADII WERE ADJUSTED BASED ON A 1351 UTC QUIKSCAT PASS
 AND A 1800 UTC OBSERVATION OF 40 KT FROM SHIP A8HR7 NORTHEAST OF
 THE CENTER.
