    TROPICAL DEPRESSION FOUR DISCUSSION NUMBER 2
    NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL042009
    1100 AM EDT SUN AUG 16 2009

    VISIBLE SATELLITE IMAGERY AND DATA FROM THE TAMPA WSR-88D INDICATE
    DEVELOPING DEEP CONVECTIVE BANDING OVER THE EAST SEMICIRCLE OF THE
    TROPICAL CYCLONE. IT APPEARS THAT THE WINDS ASSOCIATED WITH THE
    STRONGER BANDS MAY NOT YET BE MIXING DOWN TO THE SURFACE...AS NOAA
    BUOY 42036 LOCATED JUST TO THE NORTH-NORTHWEST OF THE CIRCULATION
    CENTER IS REPORTING WINDS OF LESS THAN 15 KT. AIRCRAFT
    RECONNAISSANCE WILL BE INVESTIGATING THE CYCLONE SHORTLY TO HELP
    DETERMINE IF IT HAS BECOME A TROPICAL STORM.

    ALTHOUGH REGIONAL UPPER-AIR SOUNDINGS AND WATER VAPOR IMAGERY
    SUGGEST THAT THE THERMODYNAMIC ENVIRONMENT IS ONLY MARGINALLY
    FAVORABLE...THE UPPER-LEVEL SOUTHERLY FLOW OVER THE DEPRESSION IS
    QUITE DIFFLUENT. CONSEQUENTLY...THE OFFICIAL INTENSITY FORECAST
    STILL REFLECTS STRENGTHENING JUST BEFORE LANDFALL. AFTER THAT
    TIME...WEAKENING AND DISSIPATION IS FORECAST WITHIN 48 HOURS AS THE
    SYSTEM MOVES INLAND OVER THE NORTHERN GULF COAST.

    THE INITIAL MOTION IS 330/13. THE CYCLONE IS MOVING AROUND THE
    PERIPHERY OF THE SUBTROPICAL RIDGE AND IS EXPECTED TO MAINTAIN THIS
    APPROXIMATE HEADING UNTIL LANDFALL. THE OFFICIAL FORECAST IS CLOSE
    TO A CONSENSUS OF A FAIRLY TIGHTLY CLUSTERED GUIDANCE SUITE.

    ALTHOUGH THE DEPRESSION IS VERY SMALL AND HAS A LIMITED WIND
    FIELD....HEAVY RAINFALL IS LIKELY NEAR THE TRACK OF THE CYCLONE
    ACROSS THE FLORIDA PANHANDLE...SOUTHWESTERN GEORGIA AND SOUTHERN
    ALABAMA.

    FORECAST POSITIONS AND MAX WINDS

    INITIAL 16/1500Z 28.7N 84.6W 30 KT
    12HR VT 17/0000Z 30.2N 85.8W 50 KT
    24HR VT 17/1200Z 32.1N 87.1W 35 KT...INLAND
    36HR VT 18/0000Z 34.0N 88.2W 20 KT...DISSIPATING INLAND
    48HR VT 18/1200Z...DISSIPATED
