#37975 (Received by flhurricane at: 4:40 PM 06.Aug.2005) TCDAT3 TROPICAL STORM HARVEY DISCUSSION NUMBER 18 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 PM EDT SAT AUG 06 2005 HARVEY'S CIRCULATION TOOK A SHARP LEFT HOOK LATE THIS MORNING...AND THE LOW-LEVEL CENTER NEVER FULLY CONNECTED WITH THE EARLIER CONVECTIVE BURST. THE SYSTEM ONCE AGAIN HAS A SHEARED APPEARANCE...WITH THE CONVECTION TO THE NORTH AND NORTHEAST OF THE CENTER. DVORAK CLASSIFICATIONS ARE UNCHANGED COMPARED TO 6 HOURS AGO AND SO I WILL LEAVE THE INITIAL INTENSITY AT 50 KT. ADDITIONAL INTENSIFICATION NOW APPEARS LESS LIKELY BEFORE COOLER WATERS ARE ENCOUNTERED WITHIN 24 HOURS. HOWEVER...HARVEY IS LIKELY TO FIND NEW LIFE AS AN EXTRATROPICAL CYCLONE IN 36-48 HOURS. AFTER COMPLETING A SMALL CYCLONIC LOOP...HARVEY APPEARS TO BE RESUMING A NORTH-NORTHEASTWARD MOTION. THE ADVISORY MOTION IS 030/7. WATER VAPOR IMAGERY SHOWS THE NEXT SHORT WAVE IN THE WESTERLIES OFF OF NEW ENGLAND IS PUSHING EASTWARD. THIS IS EXPECTED TO HOOK UP WITH HARVEY IN ABOUT 24-36 HOURS AND INDUCE SOME ACCELERATION TO THE NORTHEAST. GLOBAL MODELS NOW SUGGEST THAT LATE IN THE FORECAST PERIOD HARVEY'S EXTRATROPICAL REMNANTS WILL COME INTO PHASE WITH ANOTHER SHORT WAVE IN THE WESTERLIES AND CUT OFF. THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS ADVISORY BUT SLOWER AFTER 96 HOURS.
