#6282 (Received by flhurricane at: 4:56 AM 28.Aug.2004) TCDAT2 TROPICAL DEPRESSION SEVEN DISCUSSION NUMBER 3 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 AM EDT SAT AUG 28 2004 SATELLITE IMAGES AND RADAR FROM CHARLESTON SUGGEST THAT THE CLOUD PATTERN ASSOCIATED WITH THE DEPRESSION IS A LITTLE BETTER ORGANIZED. THE THUNDERSTORM ACTIVITY IS LOCATED PRIMARILY TO THE EAST OF THE CENTER IN A CYCLONIC CURVED BAND. DVORAK T-NUMBERS ARE 2.0 FROM ALL AGENCIES. INITIAL INTENSITY IS ESTIMATED AT 30 KNOTS. THE SHEAR IS LOW AND THE OCEAN IS WARM...THEREFORE...THE SYSTEM COULD BECOME A TROPICAL STORM LATER TODAY. BECAUSE STEERING CURRENTS ARE VERY WEAK...THE DEPRESSION HAS BEEN NEARLY STATIONARY. HOWEVER...A RIDGE IS FORECAST TO DEVELOP TO THE NORTH AND EAST OF THE DEPRESSION. THIS PATTERN WILL LIKELY FORCE THE CYCLONE TO MOVE VERY SLOWLY TOWARD THE WEST AND THEN NORTHWEST FOR THE NEXT DAY OR TWO TOWARD THE COAST OF SOUTH CAROLINA. A MID-LATITUDE TROUGH IS FORECAST TO APPROACH AND STEER THE CYCLONE TOWARD THE NORTHEAST WITH AN INCREASE IN FORWARD SPEED. THE EXPECTED SLOW MOTION OF THE CYCLONE NEAR THE COAST OF SOUTH CAROLINA WILL LIKELY PRODUCE HEAVY RAINS.
