#5772 (Received by flhurricane at: 4:46 PM 20.Aug.2004) TCDAT4 TROPICAL DEPRESSION DANIELLE DISCUSSION NUMBER 30 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 PM EDT FRI AUG 20 2004 FINALLY...STRONG UPPER-LEVEL WINDS REMOVED MOST OF THE CONVECTION ASSOCIATED WITH DANIELLE. ALTHOUGH THE CYCLONE STILL HAS A TIGHT LOW-LEVEL CIRCULATION...IT HAS BEEN DOWNGRADED TO A 30-KNOT TROPICAL DEPRESSION. THE SHEAR IS FORECAST TO REMAIN HIGH SO WEAKENING IS EXPECTED AND THE DEPRESSION WILL LIKELY DEGENERATE INTO A REMNANT LOW IN 36 HOURS OR SO. THE CYCLONE WILL LIKELY DEVELOP INTERMETTENT BURSTS OF DEEP CONVECTION NEAR THE CENTER DURING THE NEXT FEW DAYS. DANIELLE IS DRIFTING NORTHWESTWARD AND BECAUSE A RIDGE IS FORECAST TO BUILD NORTHEAST OF THE CYCLONE...A SLOW NORTHWESTWARD AND THEN NORTHWARD TRACK IS EXPECTED THROUGH THE FORECAST PERIOD. THIS IS CONSISTENT WITH DYNAMICAL GUIDANCE WHICH UNANIMOUSLY BRINGS THE CYCLONE NORTHWESTWARD AND THEN NORTHWARD.
