TROPICAL STORM KRISTY DISCUSSION NUMBER  15 CORRECTED
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP122006
800 AM PDT SAT SEP 02 2006

...CORRECTION TO REFLECT THE STATUS OF KRISTY IN THE FORECAST...  

TROPICAL STORM KRISTY IS WEAKENING...AS THE LOW-LEVEL CIRCULATION IS
NOW EXPOSED UNDER STRONG NORTHEASTERLY SHEAR.  THE CONVECTION
PREVIOUSLY CONCENTRATED SOUTHWEST OF THE CENTER HAS ROTATED
CYCLONICALLY TOWARD THE EAST AND WHILE SOME SLIGHT INWARD WRAPPING
HAS BEEN OBSERVED...WE EXPECT CONTINUED WEAKENING AND FORECAST
DISSIPATION AT 24 HOURS.
 
KRISTY IS DRIFTING VERY SLOWLY TO THE SOUTH/SOUTHWEST AND OUR
FORECAST CALLS FOR A FASTER AND MORE OPEN U TURN THAN IN THE
PREVIOUS ADVISORY...WITH DISSIPATION SOUTHEAST OF THE STORM'S
CURRENT POSITION.  THE DYNAMICAL MODELS...SHALLOW BAM AND CONSENSUS
ALL PREDICT A FASTER U TURN IN RESPONSE TO LOW-LEVEL RIDGING TO THE
SOUTHEAST AND INCREASED WESTERLIES.  OUR SLOWER MOTION IS BASED ON
FASTER DISSIPATION THAN IN THE MODELS...BUT IS MORE CONSISTENT WITH
THE GFS SOLUTION.
