CURRENT INTENSITY IS NOW ESTIMATED TO BE ABOUT 30 KT. THE CYCLONE SHOULD CONTINUE TO SPIN DOWN BUT AT A MORE GRADUAL RATE..IN GENERAL ACCORDANCE WITH THE EXPONENTIAL INLAND DECAY MODEL. GLOBAL MODELS SUGGEST THAT GUSTAV OR ITS REMNANTS WILL INTERACT WITH A BAROCLINIC ZONE AND MERGE WITH THAT FEATURE IN 3 TO 4 DAYS. THEREFORE THE FORECAST SHOWS DISSIPATION BY DAY 5. INITIAL MOTION IS AROUND 315/9. ADDITIONAL DECELERATION IS LIKELY AS THE STEERING CURRENT WEAKENS FURTHER DURING THE NEXT DAY OR SO. THEREAFTER...THE CONSENSUS OF THE GLOBAL DYNAMICAL GUIDANCE CALLS FOR A TURN TOWARD THE NORTH AND NORTHEAST AS MID-LEVEL SOUTHWESTERLY ENVIRONMENTAL FLOW BEGINS TO IMPACT THE SYSTEM. THE OFFICIAL TRACK FORECAST FOLLOWS THIS GUIDANCE. ASIDE FROM SEVERE LOCAL STORMS...THE THREAT FROM GUSTAV HAS SHIFTED TO HEAVY RAINS AND THE ASSOCIATED INLAND FLOODING. THIS IS THE LAST ADVISORY ON GUSTAV FROM THE NATIONAL HURRICANE CENTER.
