THIS SYSTEM BARELY FITS THE DEFINITION OF A TROPICAL CYCLONE SO ADVISORIES WILL BE CONTINUED SIX MORE HOURS. SATELLITE INTENSITY ESTIMATES ARE UNCHANGED AND SO IS THE INITIAL INTENSITY OF 25 KT. THIS SYSTEM COULD DISSIPATE AT ANY TIME WITH THE CONTINUATION OF STRONG SOUTHERLY SHEAR. LITTLE CHANGE IN INTENSITY LIKELY UNTIL THE SYSTEM BECOMES EXTRATROPICAL. THE CURRENT MOTION OF 320/11 SHOULD CHANGE TO DUE NORTH SOON AHEAD OF AN APPROACHING FRONTAL SYSTEM. THIS FRONT SHOULD ABSORB DEBBY IN THE 24-36 HOUR TIMEFRAME. THE FORECAST TRACK IS SHIFTED LEFTWARD AT FIRST TO ACCOUNT FOR THE NORTHWESTWARD INITIAL MOTION THEN COMES IN LINE WITH THE MODEL CONSENSUS BY THE END OF THE PERIOD.
