It's looking quite potent -

CONDITIONS ARE EXPECTED TO REMAIN FAVORABLE FOR
INTENSIFICATION TO...AND THEN SUSTAINING...MAJOR HURRICANE STATUS.
IN FACT...THE LATEST GFDL MODEL OUTPUT FORECASTS 127 KT AND 931 MB
BY 48 HOURS...WHILE THE SHIPS GUIDANCE SHOWS ABOUT 100 KT IN 72
HOURS. THE OFFICIAL FORECAST MORE CLOSELY FOLLOWS THE SHIPS
GUIDANCE AND IS SIMILAR TO THE PREVIOUS ADVISORY...MAKING DENNIS A
MAJOR HURRICANE IN 48 HOURS.
