THE NEW GUIDANCE RUNS SHOW A SLIGHT LEFT TURN AFTER 12 HR WITH A LEFTWARD SHIFT IN THE LANDFALL POINT ON THE LOUISIANA COAST. THE NEW FORECAST TRACK WILL NOT FOLLOW THIS SHIFT YET...AND THUS LIES NEAR THE EASTERN EDGE OF THE GUIDANCE ENVELOPE AND THE PREVIOUS FORECAST TRACK THROUGH 48 HR. AFTER 48-72 HR...THERE IS MAJOR DISAGREEMENT BETWEEN THE DYNAMICAL MODELS ON WHETHER GUSTAV WILL RECURVE INTO THE WESTERLIES...STALL OVER LOUISIANA OR TEXAS...OR TURN SOUTHWESTWARD. SINCE THIS KIND OF SPREAD FREQUENTLY PRECEDES SLOW MOTION...THE FORECAST TRACK WILL CALL FOR A SLOW WESTWARD MOTION AFTER 72 HR.
