TROPICAL STORM GIL DISCUSSION NUMBER  19
NATIONAL WEATHER SERVICE MIAMI FL
8 AM PDT SAT SEP 08 2001
 
GIL HAS BECOME BADLY SHEARED...AS THE LOW-LEVEL CENTERS OF GIL AND 
HENRIETTE REVOLVE RAPIDLY AROUND EACH OTHER...AND THE LIMITED 
CONVECTION WITH GIL HAS BEEN LEFT BEHIND.  A QUIKSCAT PASS AT 0300Z 
SHOWED A RAIN-FLAGGED 60 KT VECTOR...AND DVORAK ESTIMATES ARE IN THE 
45 TO 55 KT RANGE.  THE INITIAL INTENSITY IS REDUCED TO 50 KT FOR 
THIS ADVISORY.  WATER TEMPERATURES ARE NEAR 23C AND CONTINUED 
WEAKENING IS INDICATED.    

WITH THE RAPID CO-REVOLUTION OF GIL AND HENRIETTE...THE CURRENTLY
CLOSED CIRCULATION OF GIL MAY OPEN UP AND TECHNICALLY DISSIPATE
WITHIN 12 TO 24 HOURS...AS HAS ALREADY OCCURRED WITH HENRIETTE.
AFTER BOTH CIRCULATIONS DISSIPATE...THE BROAD AREA OF LOW PRESSURE
THAT REMAINS IS EXPECTED TO MOVE SLOWLY TO THE WEST-SOUTHWEST.

THE WIND RADII FOR GIL HAVE BEEN SIGNIFICANTLY ADJUSTED TO INCLUDE 
THE WIND FIELD ASSOCIATED WITH HENRIETTE.
