TROPICAL DEPRESSION KRISTY DISCUSSION NUMBER  24

THERE WAS ANOTHER SMALL PUFF OF CONVECTION...SINCE DISSIPATED...
EARLIER THIS AFTERNOON.  A QUIKSCAT PASS FROM 14Z HAD A FEW
BELIEVABLE 30 KT VECTORS...AND THAT WILL BE THE ADVISORY INTENSITY. 
OVERALL...KRISTY'S CIRCULATION LOOKS LESS VIGOROUS THAN 24 HOURS
AGO...AND IT IS SLOWLY SPINNING DOWN.  HOWEVER...THE RECENT
CONVECTION MEANS WE WILL NEED TO WAIT A BIT LONGER BEFORE
TERMINATING ADVISORIES.  

THE INITIAL MOTION IS 225/5.  TRACK GUIDANCE CONTINUES TO SHOW AN
INCREASING WESTWARD MOTION...IN RESPONSE TO THE MID AND UPPER-LEVEL
EASTERLIES...THAT KRISTY WITH ITS ANEMIC CONVECTION CONTINUES TO
IGNORE.  THE OFFICIAL FORECAST PRESUMES THAT KRISTY WILL REMAIN
MOSTLY NON-CONVECTIVE AND INTERACT MINIMALLY WITH THE EASTERLIES. 
AS A RESULT...IT IS CONSIDERABLY SLOWER THAN JUST ABOUT ALL OF THE
TRACK GUIDANCE.

BOTH THE SHIPS AND GFDL GUIDANCE RE-INTENSIFY THE CYCLONE TO A
STRONG TROPICAL STORM.  HOWEVER...EASTERLY SHEAR AND UNFAVORABLE
ATMOSPHERIC THERMODYNAMICS HAVE BEEN LIMITING CONVECTION...AND I
SEE NO REASON WHY THIS SHOULD NOT CONTINUE.  GLOBAL MODELS PREDICT
A DECREASE IN EASTERLY SHEAR...BUT WATER VAPOR IMAGERY SHOWS STRONG
EASTERLIES UPSTREAM AND HEADED KRISTY'S WAY.  THE MOST LIKELY
SCENARIO IS THAT KRISTY WILL DEGENERATE TO A REMNANT LOW DURING THE
NEXT 12 TO 24 HOURS.
