Daniel we always here talk of them creating their own environment as Cat 5... maybe that's what Ivan is doing.. he'll go where he wants to...

interesting comment on this subject on the NO AFD this afternoon

ANOTHER CONCERN IS HISTORICAL TRACKS OF
CATEGORY 4 AND 5 HURRICANES IN SEPTEMBER IN THE NORTHWEST CARRIBEAN SEA ARE MOSTLY WEST-NORTHWEST ACROSS YUCATAN...THEN MAINLAND MEXICO...LIKE GILBERT. LARGER STORMS TEND TO CREATE THEIR OWN ENVIRONMENT AND HAVE LESS INFLUENCE FROM SURROUNDING FEATURES.
HOWEVER...AS WE HAVE SEEN THE LAST SEVERAL YEARS...THERE HAVE BEEN NUMEROUS STORMS THAT HAVE GONE AGAINST CLIMATOLOGY...SO THERE WILL
BE A LOT OF UNCERTAINTY ON THE TRACK AND FUTURE STRENGTH OF IVAN. MODEL TRENDS CONTINUE TO TAKE IVAN A BIT FARTHER WEST WITH EACH
MODEL RUN...BUT MOST ARE WELL CLUSTERED NOW AND SUGGESTING A U.S. LANDFALL NEAR PANAMA CITY FL WEDNESDAY AFTERNOON. THE BREAK IN THE
UPPER RIDGE JUST TO OUR EAST AND THE SOUTHWEST UPPER LEVEL WINDS TO
THE EAST OF THE TROUGH AXIS SHOULD CAUSE IVAN TO TURN NORTH AND POSSIBLY NORTH-NORTHEAST AS HE NEARS THE NORTH GULF COAST. IT IS STRONGLY ADVISED THAT EVERYONE WATCH FUTURE DEVELOPMENTS OF THIS HURRICANE.
