THE AVERAGE MOTION OVER THE PAST 6 HOURS IS 290/07...ALTHOUGH THE
MOTION OVER THE PAST 3 HOURS HAS BEEN ALMOST DUE WEST. THE PRIMARY
STEERING MECHANISM FOR THE NEXT 5 DAYS WILL BE THE LARGE MID- TO
UPPER-LEVEL ANTICYCLONE CENTERED OVER THE FLORIDA STRAITS...WHICH
IS FORECAST TO AMPLIFY NORTHWARD OVER THE SOUTHEASTERN U.S. AND AN
UPPER-LEVEL TROUGH OVER THE NORTHWESTERN GULF IS ALSO EXPECTED TO
BE A PLAYER AND ACT TO SLOW DOWN GUSTAV BY DAY 5. THE EXCEPTIONS
ARE THE GFDL AND ECMWF MODELS...WHICH BLAST GUSTAV NORTHWESTWARD
THROUGH THE UPPER-TROUGH TO THE TEXAS COAST. THIS SEEMS PHYSICALLY
UNLIKELY AT THIS JUNCTURE.
