HURRICANE CINDY DISCUSSION NUMBER  40
NATIONAL WEATHER SERVICE MIAMI FL
5 PM EDT SAT AUG 28 1999
 
OBJECTIVE DVORAK ESTIMATES USING THE UW-CIMSS ALGORITHM SHOW THAT
THE INTENSITY OF CINDY PEAKED THIS MORNING.  A RECENT 3-HR AVERAGE
OF 5.9 SUPPORTS ABOUT 115 KT.  CI NUMBERS FROM TAFB AND SAB ARE 127
AND 115 KT...RESPECTIVELY.  THE OFFICIAL INTENSITY WILL REMAIN AT
120 KT FOR THIS PACKAGE BUT WILL PROBABLY BE LOWERED TONIGHT.
 
THE INITIAL MOTION ESTIMATE IS STILL 335/8.  THERE IS LITTLE CHANGE
IN EITHER THE TRACK FORECAST PHILOSOPHY AND THE OFFICIAL FORECAST
MERELY UPDATES THE PREVIOUS PACKAGE.  ALL GUIDANCE INDICATES THAT
CINDY WILL RECURVE INTO THE WESTERLIES WITHIN 24 HOURS AND
ACCELERATE THEREAFTER.  THE FORECAST CALLS FOR CINDY TO BECOME
EXTRATROPICAL AT 72 HOURS.

THE RADII OF THE 12 FOOT SEAS HAVE BEEN EXPANDED BASED ON NUMEROUS
SHIP OBSERVATIONS THIS AFTERNOON.
