1 PM EDT SUN SEP 05 2004
...CORRECT TO SHOW INLAND AT 120HR ONLY...
THE PURPOSE OF THIS SPECIAL ADVISORY IS TO REPORT THE RAPID
INTENSIFICATION OF IVAN OVER THE LAST FEW HOURS.  A SPECIAL DVORAK
CLASSIFICATION FROM TAFB AND DATA T-NUMBERS GAVE AN INTENSITY OF
ABOUT 100 KT.  OBJECTIVE DVORAK T-NUMBERS SUGGEST THAT EVEN THIS
ESTIMATE MAY BE CONSERVATIVE.  SOME ADDITIONAL STRENGTHENING IS
LIKELY BUT WE SHOW THE INTENSITY LEVELLING OFF WITHIN THE NEXT DAY
OR TWO TO REFLECT UNCERTAINTIES.

NO CHANGES TO THE TRACK OR WIND RADII FORECASTS HAVE BEEN MADE.
