POST-TROPICAL CYCLONE MICHAEL DISCUSSION NUMBER  35
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL132012
500 PM AST TUE SEP 11 2012
 
MICHAEL CONSISTS OF A TIGHT SWIRL OF LOW CLOUDS THAT HAS BEEN DEVOID
OF DEEP CONVECTION FOR MOST OF THE DAY. GIVEN THE LACK OF
THUNDERSTORM ACTIVITY MICHAEL IS NO LONGER A TROPICAL CYCLONE.
SINCE THE CYCLONE IS ALREADY OVER COOL WATERS AND EMBEDDED WITHIN
STRONG SHEAR...ADDITIONAL WEAKENING IS ANTICIPATED. MICHAEL IS
FORECAST TO BECOME ABSORBED BY A COLD FRONT IN ABOUT 24 HOURS.
 
THE INITIAL MOTION IS 025 DEGREES AT 27 KNOTS.  MICHAEL IS BEING
STEERED BY THE SOUTHERLY FLOW BETWEEN A WEAK SUBTROPICAL HIGH TO THE
EAST AND A STRONG TROUGH APPROACHING FROM THE WEST. THIS WILL RESULT
IN AN INCREASE IN FORWARD SPEED UNTIL THE SYSTEM BECOMES ABSORBED
BY A FRONT.
 
THIS IS THE LAST ADVISORY ON MICHAEL ISSUED BY THE NATIONAL
HURRICANE CENTER.
