#58585 (Received by flhurricane at: 9:40 AM 26.Nov.2005) TCDAT3 TROPICAL STORM DELTA DISCUSSION NUMBER 12 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 10 AM EST SAT NOV 26 2005 DELTA CONSISTS OF AN EXPOSED AND WELL-DEFINED LOW LEVEL CIRCULATION WITH A CURVED BAND OF DEEP CONVECTION TO THE EAST OF THE CENTER. INITIAL INTENSITY HAS BEEN LOWERED TO 35 KNOTS BASED ON DVORAK T-NUMBERS FROM ALL AGENCIES. BECAUSE THE CYCLONE IS EXPECTED TO MOVE TOWARD COOLER WATERS AND WITHIN AN EVEN STRONGER WIND SHEAR ENVIRONMENT...ADDITIONAL WEAKENING IS ANTICIPATED. DELTA SHOULD BECOME EXTRATROPICAL IN A DAY OR SO. DELTA IS NOW MOVING TOWARD THE NORTHEAST ABOUT 8 KNOTS. THE CYCLONE IS EXPECTED TO CONTINUE TOWARD THE NORTHEAST FOR A DAY OR SO WITHIN THE FLOW AROUND A DEVELOPING MID-LATITUDE TROUGH ALONG 50 DEGREES WEST. THEREAFTER...A TURN TO THE EAST WITH AN INCREASE IN FORWARD SPEED IS ANTICIPATED AS DELTA BECOMES FULLY EMBEDDED WITHIN THE WESTERLY FLOW ASSOCIATED WITH A LARGE CYCLONE OVER WESTERN EUROPE. THE DEVELOPMENT OF THIS STEERING PATTERN IS INDICATED BY ALL OF THE AVAILABLE GLOBAL MODELS AND THERE ARE NO OBVIOUS REASONS TO ASSUME ANOTHER SOLUTION.
