DOPPLER VELOCITIES HAVE GRADUALLY BEEN DECREASING AND THERE HAVE NOT BEEN ANY RECENT REPORTS OF STRONG WINDS NEAR THE CENTER. HOWEVER... IT IS POSSIBLE THAT 35 KT WINDS ARE STILL OCCURRING IN THE STRONG CONVECTION OVER WATER TO THE SOUTHEAST OF THE CENTER. ON THIS BASIS...CLAUDETTE IS BEING MAINTAINED AS A TROPICAL STORM WITH AN INITIAL INTENSITY OF 35 KT. CLAUDETTE IS EXPECTED TO WEAKEN TO A TROPICAL DEPRESSION LATER THIS MORNING AS THE CENTER MOVES FARTHER INLAND. CLAUDETTE IS FORECAST TO MOVE AROUND THE WESTERN PERIPHERY OF A MID-LEVEL HIGH PRESSURE AREA OFF THE SOUTHEASTERN UNITED STATES. THE NEW TRACK FORECAST IS A LITTLE WEST OF THE PREVIOUS NHC ADVISORY...NEAR THE MIDDLE OF THE LATEST MODEL ENVELOPE. THE MAIN CONCERN WITH THIS SYSTEM IS LOCALLY HEAVY RAINFALL AND INLAND FLOODING. PLEASE REFER TO STATEMENTS...WATCHES...AND WARNINGS FROM LOCAL NATIONAL WEATHER SERVICE FORECAST OFFICES.
