This is the only prediction I will make on this storms future, but I think the cone will move quite a bit west in the next 24hrs. I am stating this only by looking at past (last 24-48hr) loops and watching environment variables changing. I stand by my thoughts that the easternly shift in models was due to the GulfstreamIV data, but, hey, we shall see.


Totally agreed. I think ridge will show up and put it back on a more WNW track in 24 hours or less.

HURRICANE DENNIS DISCUSSION NUMBER 13
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT THU JUL 07 2005

LATEST DATA FROM THE AIR FORCE HURRICANE HUNTERS SHOW THAT THE
CENTRAL PRESSURE HAS BEEN FALLING AT SLIGHTLY OVER 1 MB PER HOUR
SINCE EARLY THIS MORNING. THE EYE HAS SHRUNK TO ABOUT 9 N MI
DIAMETER AND THE EYEWALL IS NOW CLOSED. ENVIRONMENTAL CONDITIONS
REMAIN QUITE FAVORABLE FOR STRENGTHENING AND THE OFFICIAL FORECAST
SHOWS A BORDERLINE CATEGORY 4 HURRICANE IN 12 HOURS. DENNIS IS
EXPECTED TO WEAKEN SOMEWHAT OVER CUBA...BUT IT SHOULD REGAIN
STRENGTH WHEN IT EMERGES OVER THE SOUTHEASTERN GULF OF MEXICO.
ALTHOUGH THE WIND SHEAR MAY BECOME LESS FAVORABLE FOR
INTENSIFICATION OVER THE NORTHEAST GULF OF MEXICO...THE OFFICIAL
FORECAST MAINTAINS DENNIS AS A MAJOR HURRICANE UP TO LANDFALL IN
THAT AREA.

THE MOTION CONTINUES TOWARD THE NORTHWEST...310/13. THIS MOTION
SHOULD TAKE THE CENTER OF THIS DANGEROUS HURRICANE OVER CENTRAL
CUBA WITHIN 24 HOURS. DENNIS IS THEN EXPECTED TO MOVE AROUND THE
WESTERN PERIPHERY OF A SUBTROPICAL RIDGE. ALTHOUGH THIS SOUNDS
SIMPLE ENOUGH...THE DETAILS OF THE TURN AROUND THE RIDGE ARE
IMPORTANT FOR RESIDENTS OF FLORIDA. IN THE LATEST MODEL RUNS...THE
GFS HAS SHIFTED A LITTLE FARTHER EAST AND IS NOW VERY CLOSE TO THE
GFDL TRACK. THESE TWO MODELS ARE THE EASTERNMOST OF THE DYNAMICAL
SUITE. THE U.K. MET. OFFICE MODEL REMAINS WELL WEST OF ALMOST ALL
OTHER GUIDANCE. OUR FORECAST IS ADJUSTED ONLY SLIGHTLY TO THE EAST
AND IS VERY CLOSE TO BOTH THE SIMPLE DYNAMICAL CONSENSUS TRACK...
CONU...AND TO THE FSU SUPERENSEMBLE.

A HURRICANE WARNING IS NOW POSTED FOR THE LOWER FLORIDA KEYS SINCE
TROPICAL STORM FORCE WINDS COULD REACH THOSE ISLANDS BY TOMORROW
AFTERNOON.

That's category 2 after landfall in Cuba. Dennis crossing Cuba is what brings the winds down from the 115 kt at landfall. The are projecting landfall there as a minimal category 4 storm.
