VISIBLE SATELLITE PICTURES STRONGLY SUGGEST THAT THE CIRCULATION
CENTER HAS MOVED UNDER THE CLUSTER OF DEEP CONVECTION.  THIS
REQUIRES A RELOCATION OF THE ESTIMATED CENTER POSITION...AHEAD AND
TO THE NORTH OF THE PREVIOUS ADVISORY LOCATION.  EVEN WITH THE
RELOCATION...THE SYSTEM APPEARS TO STILL BE ACCELERATING AND IS NOW
MOVING AT ABOUT  050/20 KT.  THIS STRUCTURE HAS BEEN INTERPRETED AS
A DVORAK 2.5+ AND 2.5 RESPECTIVELY BY TSAF AND SAB.  HENCE...THE
SYSTEM IS UPGRADED TO TROPICAL STORM HARVEY.
 
THE TRACK MODELS INDICATE A CONTINUE RAPID FORWARD MOTION AND
SHEARING CONDITIONS.  THE OFFICIAL FORECAST GENERALLY ALSO SHOWS AN
EXTENSTION OF THE CURRENT MOTION.  THE SYSTEM WILL HAVE SPENT
CONSIDERABLE TIME OVER COLDER WATERS AT HIGH LATITUDES BY 72
HOURS...AND IS FORECAST TO BECOME EXTRATROPICAL BY THAT TIME.
