HURRICANE WILMA DISCUSSION NUMBER  42
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT TUE OCT 25 2005
 
MORNING SATELLITE IMAGERY SHOWS THAT WILMA IS WEAKENING AND
BEGINNING TO LOSE TROPICAL CHARACTERSTICS.  AN SSM/I OVERPASS AT
1117Z SHOWS THAT THE CENTER IS NORTHWEST OF THE PRIMARY
CONVECTION...WHILE VISIBLE IMAGERY SHOWS COLD AIR CLOUDS SOUTH OF
THE CENTER AND A DEVELOPING COLD FRONT IN THE SOUTHEASTERN
QUADRANT.  WILMA SHOULD MOVE NORTH OF THE GULF STREAM IN THE NEXT
12-24 HR...WHICH SHOULD FINISH OFF THE REMAINING CENTRAL CONVECTION
AND THE REMAINING TROPICAL CHARACTERISTICS.  THE LARGE-SCALE MODELS
LIKE TO LOSE WILMA IN THE WARM FRONT OF A BAROCLINIC LOW CENTERED
NEAR THE NORTHEASTERN COAST OF THE UNITED STATES IN LESS THAN 72
HR.  GIVE THE STRENGTH OF THE SYSTEM...IT WILL PROBABLY LAST A BIT
LONGER THAN THAT.

THE INITIAL MOTION IS A VERY RAPID 045/046.  ASSUMING WILMA IS NOT
ABSORBED BY THE BAROCLINIC LOW...THE FORECAST TRACK WILL TURN THE
CYCLONE EASTWARD OVER THE TOP OF A DEEP-LAYER RIDGE IN THE CENTRAL
ATLANTIC THROUGH 72 HR...FOLLOWED BY AN EAST-NORTHEASTWARD MOTION
BEFORE DISSIPATION.
