HURRICANE ILEANA DISCUSSION NUMBER  15
NWS NATIONAL HURRICANE CENTER MIAMI FL       EP092012
200 AM PDT FRI AUG 31 2012
 
A LARGE PORTION OF THE NORTHERN SEMICIRCLE OF ILEANA IS ALREADY OVER
COOLER WATERS...AND CONSEQUENTLY MOST OF THE CONVECTION IS OCCURRING
IN THE SOUTHERN SEMICIRCLE. DVORAK T-NUMBERS ARE DECREASING...AND
THE INITIAL INTENSITY HAS BEEN LOWERED TO 65 KNOTS. GIVEN THAT
ILEANA WILL CONTINUE TO MOVE TOWARD LOWER SEA SURFACE TEMPERATURES
AND BECOME INVOLVED WITH STABLE AIR...THE NHC FORECAST CALLS FOR
WEAKENING.

ILEANA IS MOVING TOWARD THE NORTHWEST OR 320 DEGREES AT 10 KNOTS. 
TRACK MODELS ARE NOT IN AGREEMENT AT ALL...WITH SOME MOVING ILEANA
NORTHWARD AND OTHERS KEEPING THE CYCLONE WESTWARD. SINCE ILEANA IS
FORECAST TO WEAKEN AND BECOME A SHALLOW CYCLONE...THERE IS A STRONG
LIKELIHOOD THAT IT WILL TURN WESTWARD STEERED BY THE LOW-LEVEL
FLOW UNTIL DISSIPATION.
