Hurricane Dean

NEAR 0500 UTC…AN AIR FORCE RESERVE HURRICANE HUNTER AIRCRAFT REPORTED 154 KT FLIGHT-LEVEL WINDS IN THE NORTHERN EYEWALL OF DEAN…AND ALSO REPORTED THAT THE CENTRAL PRESSURE FELL TO 930 MB.

THE FLIGHT-LEVEL WINDS COULD HAVE JUSTIFIED CALLING DEAN A CATEGORY FIVE HURRICANE.  HOWEVER…DATA FROM DROPSONDES…THE STEPPED-FREQUENCY MICROWAVE RADIOMETER…AND SATELLITE INTENSITY ESTIMATES DID NOT SUPPORT THAT STATUS.  THE INTENSITY WAS THUS SET TO A SLIGHTLY MORE CONSERVATIVE 130 KT.  THERE HAS BEEN LITTLE CHANGE IN THE SATELLITE APPEARANCE OF DEAN SINCE THE AIRCRAFT LEFT…SO 130 KT IS THE INITIAL INTENSITY FOR THIS ADVISORY.
