From the last Ivan discussion:
THE INITIAL MOTION IS 025/12. NHC MODEL GUIDANCE HAS CONTINUED TO COME INTO BETTER AGREEMENT THAT IVAN WILL GRADUALLY CURVE NORTHEASTWARD AND THEN EASTWARD...AND DECELERATE THROUGH 48 HR. AFTER THAT... A HIGH AMPLITUDE SURFACE TO MID-LEVEL RIDGE IS FORECAST TO BUILD OVER THE NORTHEASTERN U.S....WHICH WILL ACT TO BLOCK IVAN AND TURN THE REMNANT CIRCULATION SLOWLY SOUTHWESTWARD OVER SOUTH CAROLINA AND GEORGIA.

SINCE THE REMNANT IVAN CIRCULATION WILL REMAIN INTACT...AT LEAST IN THE MID-LEVELS OF THE TROPOSPHERE THROUGHOUT THE FORECAST PERIOD...
A MAJOR RAINFALL EVENT APPEARS LIKELY THE NEXT SEVERAL DAYS OVER MUCH OF THE SOUTHEASTERN U.S. THERE IS ALSO A CONTINUED TORNADO THREAT ACROSS A LARGE PORTION OF THE SOUTHEASTERN UNITED STATES TONIGHT AND FRIDAY.
