POST-TROPICAL CYCLONE CINDY DISCUSSION NUMBER  10
NWS NATIONAL HURRICANE CENTER MIAMI FL       AL032011
1100 PM AST FRI JUL 22 2011
 
DEEP CONVECTION ASSOCIATED WITH CINDY HAS EVAPORATED AND THE
CIRCULATION IS BECOMING ILL DEFINED. AN EARLIER 1950 UTC NRL
WINDSAT OVERPASS INDICATED A FEW BELIEVABLE 35 KT WINDS BUT DID NOT
SHOW A CLOSED CIRCULATION...INDICATING ONLY A SHARP TROUGH. THE
METEOSAT 9 SHORT WAVE INFRARED IMAGERY...HOWEVER...SUGGESTS THAT A
SMALL CLOSED CIRCULATION MAY STILL EXIST. IN ANY EVENT...CINDY
LACKS THE CONVECTION REQUIRED OF A TROPICAL CYCLONE AND THIS WILL
BE THE LAST ADVISORY. THE INITIAL INTENSITY IS LOWERED TO 35 KT
BASED ON THE DVORAK SATELLITE INTENSITY ESTIMATES AND THE
SCATTEROMETER PASS. STRONG NORTHERLY SHEAR AND COLD SEA SURFACE
TEMPERATURES SHOULD PREVENT THE POST-TROPICAL CYCLONE FROM
REDEVELOPING ORGANIZED CONVECTION...AND ULTIMATELY SHOULD CAUSE
DISSIPATION IN 24 HOURS OR LESS.
 
THE INITIAL MOTION IS ESTIMATED TO BE 050/29...AND THE SYSTEM IS
EXPECTED TO FURTHER ACCELERATE TOWARD THE NORTHEAST UNTIL
DISSIPATION. FOR ADDITIONAL INFORMATION ON THE POST-TROPICAL
CYCLONE PLEASE SEE HIGH SEAS FORECASTS ISSUED BY THE METEO FRANCE
MET OFFICE...UNDER WMO HEADER FQNT50 LFPW.
