FERNANDA HAS BEEN UNABLE TO MAINTAIN PERSISTENT DEEP CONVECTION FOR
OVER 18 HOURS AND ITS LOW LEVEL CIRCULATION CENTER...LLCC...HAS
BEEN FULLY EXPOSED ALL DAY.  GIVEN THE LACK OF ORGANIZED DEEP
CONVECTION...THIS SYSTEM IS NOW CONSIDERED TO BE POST-TROPICAL.

TEMPERATURES BETWEEN 25C AND 26C MEAN THAT REGENERATION IS NOT
LIKELY. THUS...THIS IS THE LAST ADVISORY ON FERNANDA.

WITHIN THE LOW LEVEL TRADE WINDS BEFORE DISSIPATING WITHIN A COUPLE
OF DAYS. FOR FUTURE INFORMATION ON THE REMNANT LOW PLEASE SEE HIGH
