#5795 (Received by flhurricane at: 10:42 PM 20.Aug.2004) TCDAT4 TROPICAL DEPRESSION DANIELLE DISCUSSION NUMBER 31 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 11 PM EDT FRI AUG 20 2004 DANIELLE CONTINUES TO GENERATE INTERMITTENT BURSTS OF DEEP CONVECTION NEAR THE CENTER AND THE INITIAL INTENSITY IS HELD AT 30 KT. VERTICAL SHEAR IS EXPECTED TO REMAIN HIGH AND DANIELLE WILL BE TRACKING OVER A PROGRESSIVELY COOLER OCEAN. ACCORDINGLY...THE OFFICIAL INTENSITY FORECAST CALLS FOR A SLOW WEAKENING AND DANIELLE WILL LIKELY DEGENERATE INTO A REMNANT LOW IN 36 HOURS OR SO. IT SHOULD BE NOTED THAT THERE MAY BE A SMALL WINDOW OF OPPORTUNITY FOR DANIELLE TO RE-INTENSIFY BETWEEN 24-48 HR AS INDICATED BY THE SHIPS MODEL...BUT THIS REMAINS AN ALTERNATIVE FORECAST SCENARIO FOR THIS ADVISORY. DANIELLE REMAINS WITHIN AN AREA OF WEAK STEERING AND THE SYSTEM HAS BEEN MEANDERING OVER THE LAST 24 HOURS. THE CURRENT INITIAL MOTION ESTIMATE IS 315/04. DANIELLE IS EXPECTED TO CONTINUE ON A GENERAL NORTHWESTWARD MOTION OVER THE NEXT DAY OR SO AS A DEEP LAYER RIDGE BUILDS TO THE NORTHEAST...AND THEN BEGIN TO RECURVE NORTHEASTWARD AHEAD OF THE NEXT WESTERLY TROUGH. THE OFFICIAL NHC TRACK IS SHIFTED SLIGHTLY LEFT AND IS ON THE RIGHT SIDE OF THE GUIDANCE ENVELOPE.
