THE LITTLE REMAINING DEEP CONVECTION HAS BEEN SHEARED NORTHEAST AWAY
FROM THE LOW-LEVEL CENTER OF LANE. THE INITIAL INTENSITY IS
DECREASED TO 35 KT BASED ON THE LATEST DVORAK FINAL-T NUMBERS FROM
TAFB AND SAB. A QUICK DEMISE TO REMNANT LOW STATUS IS EXPECTED BY
24 HOURS AS LANE MOVES OVER SSTS LESS THAN 22C. THE REMNANT LOW
SHOULD DISSIPATE IN 2 TO 3 DAYS AS INDICATED BY THE GLOBAL MODELS.

THE INITIAL MOTION ESTIMATE IS 300/08...A LITTLE TO THE LEFT OF AND
FASTER THAN THE PREVIOUS FORECAST. THE DECAYING VORTEX WILL BE
STEERED GENERALLY WESTWARD OR EVEN A LITTLE SOUTH OF DUE WEST BY
THE LOW-LEVEL SUBTROPICAL RIDGE THROUGH DISSIPATION. THE NEW NHC
TRACK FORECAST IS A LITTLE TO THE SOUTH OF AND FASTER THAN THE
PREVIOUS ONE...TRENDING TOWARD A CONSENSUS OF THE LATEST GFS AND
ECMWF MODELS.
