LATEST INFRARED IMAGERY DEPICT IRWIN AS DEVOID OF DEEP CONVECTION
AND IT IS MAINLY A SWIRL OF LOW CLOUDS. TAFB AND SAB BOTH FOUND THE

THE INITIAL MOTION IS ESTIMATED AT 270/6. THE REMNANT LOW OF IRWIN
IS EXPECTED TO MOVE IN A GENERALLY WESTWARD MOTION WITHIN THE
LOW-LEVEL ENVIRONMENTAL FLOW DURING THE NEXT 36 HOURS BEFORE

WILL BE THE LAST ADVISORY ISSUED ON IRWIN...UNLESS REGENERATION
OCCURS.
