TROPICAL STORM KENNETH DISCUSSION NUMBER  30
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 PM PDT WED SEP 21 2005
 
VISIBLE AND INFRARED IMAGERY DEPICTS A NEW BURST OF DEEP CONVECTION
NEAR THE CIRCULATION CENTER. AN EARLIER AMSU-B MICROWAVE OVERPASS
SUGGESTS THAT THE CIRCULATION CENTER REMAINS PARTIAL EXPOSED TO THE
NORTH OF THE BANDING. APPARENTLY...SOME NORTHEASTERLY SHEAR IS
CAUSING THIS CLOUD PATTERN. INITIAL INTENSITY REMAINS AT 45
KT...BASED ON THE DVORAK T- NUMBERS FROM AFWA AND TAFB. THE UW-CIMSS
SHEAR PRODUCT INDICATES 10 TO 20 KT OF NORTHEASTERLY SHEAR OVER THE
SYSTEM..AND THE UPPER-LEVEL OUTFLOW HAS BECOME A LITTLE BETTER
DEFINED.  HOWEVER... THE TROPICAL CYCLONE WILL BE MOVING WITHIN A
MORE STABLE AIR MASS...SO GRADUAL WEAKENING IS FORECAST...WITH THE
TROPICAL STORM FORECAST TO BECOME A DEPRESSION OVER THE NEXT 3
DAYS.

THE INITIAL MOTION IS 295/6. KENNETH SHOULD SLOWLY MOVE GENERALLY
WEST-NORTHWESTWARD WITHIN THE MID- LEVEL FLOW OF A RIDGE EXTENDING
WESTWARD OVER THE EASTERN PACIFIC FROM TEXAS/MEXICO THROUGH THE
FORECAST PERIOD. THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS
PACKAGE AND IS BASED OFF OF A BLEND OF THE UKMET/NOGAPS/FSU
SUPERENSEMBLE AND GFDN.
