DVORAK T-NUMBERS SUPPORT AN INITIAL INTENSITY OF 75 KNOTS. A SLIGHT WEAKENING IS EXPECTED DURING THE NEXT DAY OR SO. THERAFTER...NATE SHOULD BEGIN TO ACQUIRE EXTRATROPICAL CHARACTERISTICS IN ABOUT 72 HOURS AS IT MOVES OVER COOLER WATER AND HIGHER SHEAR AND THEN BECOME ABSORBED BY A MUCH LARGER EXTRATROPICAL CYCLONE. NATE HAS BEEN ACCELERATINGLY AND IS NOW MOVING TOWARD THE NORTHEAST ABOUT 14 KNOTS....WELL EMBEDDED WITHIN THE SOUTHWESTERLY MID-LATITUDE FLOW.
