HURRICANE IVAN DISCUSSION NUMBER  56
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 AM EDT THU SEP 16 2004
 
THE EYE OF IVAN CROSSED THE COAST AROUND 0700Z JUST WEST OF GULF
SHORES ALABAMA AS A CATEGORY THREE HURRICANE ON THE SAFFIR/SIMPSON
HURRICANE SCALE. BEST ESTIMATE OF THE INITIAL INTENSITY NOW IS 100
KNOTS AND BECAUSE IVAN IS ALREADY INLAND...FURTHER WEAKENING IS
ANTICIPATED. HOWEVER...SINCE IVAN IS SO LARGE AND INTENSE...IT IS
EXPECTED TO BRING HURRICANE FORCE WINDS WELL INLAND...UP TO ABOUT
150 MILES ALONG ITS TRACK.
 
THE HURRICANE IS MOVING TOWARD THE NORTH OR 010 DEGREES AT 12 KNOTS.
THIS GENERAL TRACK IS EXPECTED DURING THE NEXT DAY OR TWO.
THEREAFTER....IVAN IS EXPECTED TO BE BLOCKED BY A DEVELOPING HIGH
PRESSURE SYSTEM. THEREFORE...THE OFFICIAL FORECAST SHOWS IVAN
STALLING NEAR THE SOUTHERN APPALACHIANS AND SLOWLY DISSIPATING IN
THAT AREA.  OBVIOUSLY THIS COULD BE A MAJOR FLOOD EVENT OVER
PORTIONS OF THE SOUTHEASTERN U.S. IN THE COMING DAYS.
