TROPICAL STORM BORIS DISCUSSION NUMBER  11

THE CENTER IS A LITTLE MORE TUCKED IN THE CONVECTION BUT THE OVERALL
CLOUD PATTERN HAS NOT CHANGED SIGNIFICANTLY. DVORAK T-NUMBERS
CONTINUE TO SUPPORT AN INITIAL INTENSITY OF 45 KNOTS.  BORIS IS
HEADING TOWARD COOLER WATERS AND INTO MORE STABLE AIR.
THEREFORE...A GRADUAL WEAKENING SHOULD BEGIN AND THIS FORECAST
BASICALLY FOLLOWS THE SHIPS GUIDANCE.
 
BORIS HAS CONTINUED TO MOVE TOWARD THE WEST AT ABOUT 8 KNOTS. SOME
GLOBAL MODELS ARE CHANGING THEIR TUNE AND ARE NOW KEEPING BORIS
SEPARATED FROM THE DEVELOPING DISTURBANCE TO THE EAST.
CONSEQUENTLY...THESE MODELS KEEP BORIS MOVING WESTWARD.  NOW ONLY
THE GFS AND THE GFDL INSIST ON MERGING BORIS WITH THE NEW
DISTURBANCE. THE OFFICIAL FORECAST CONTINUES TO CALL FOR A SLOW
WESTWARD MOTION UNTIL BORIS BECOMES A REMNANT LOW IN 3 OR 4 DAYS.
