TROPICAL STORM ILEANA DISCUSSION NUMBER  21
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP092012
200 PM PDT SAT SEP 01 2012
 
ILEANA IS NOW VOID OF DEEP CONVECTION EXCEPT FOR A FEW SMALL CELLS
NEAR THE CENTER. THE 35-KT INITIAL INTENSITY IS BASED ON A BLEND OF
THE LATEST DVORAK FINAL-T AND CI NUMBERS FROM TAFB AND SAB. ILEANA
SHOULD CONTINUE TO SPIN DOWN AS IT MOVES OVER COOL WATERS...AND THE
CYCLONE IS EXPECTED TO BECOME A REMNANT LOW IN 24 HOURS. HOWEVER...
THIS COULD OCCUR SOONER IF DEEP CONVECTION DOES NOT REDEVELOP. 

THE INITIAL MOTION ESTIMATE IS 275/09. ILEANA SHOULD TURN SOUTH OF
DUE WEST IN A DAY OR SO AS THE CYCLONE BECOMES STEERED BY THE
NORTHEAST PACIFIC LOW-LEVEL RIDGE. THE NEW NHC FORECAST HAS BEEN
SHIFTED TO THE LEFT OF THE PREVIOUS ONE AS THE GLOBAL MODELS ARE
SHOWING A MORE SOUTHERLY COMPONENT OF MOTION AFTER 24 HOURS.
