NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 AM EDT FRI AUG 05 2005
 
STRONG UPPER-LEVEL WIND SHEAR HAS BECOME ESTABLISHED OVER HARVEY AND
THE LOW-LEVEL CENTER HAS BECOME FULLY EXPOSED. THE CENTER IS
LOCATED TO THE SOUTHWEST OF THE AREA OF DEEP CONVECTION...BUT THE
CYCLONE STILL HAS A VERY TIGHT AND WELL-DEFINED CIRCULATION AS
INDICATED BY CONVENTIONAL VISIBLE SATELLITE IMAGES AND HIGH
RESOLUTION QUICKSCAT. INITIAL INTENSITY HAS BEEN LOWERED TO 50
KNOTS. THE SHEAR IS NOT EXPECTED TO RELAX...SO A GRADUAL WEAKENING
IS INDICATED.
 
AS ANTICIPATED...STEERING CURRENTS ARE WEAKENING AND HARVEY IS
MEANDERING EASTWARD ABOUT 4 KNOTS.  WITH A LITTLE RIDGING DEVELOPING
TO THE EAST...THE CYCLONE IS EXPECTED TO DRIFT TOWARD THE NORTHEAST
FOR THE NEXT DAY OR TWO UNTIL AN APPROACHING SHORTWAVE ACCELERATES
THE WESTERLY FLOW BY 48 HOURS OR SO. HARVEY SHOULD THEN INCREASE
ITS FORWARD SPEED AND GRADUALLY BECOME EXTRATROPICAL OVER THE
COOLER WATERS OF THE NORTH ATLANTIC.
