| #5092 (Received by flhurricane at: 11:10 AM 14.Aug.2004) TCDAT3 HURRICANE CHARLEY DISCUSSION NUMBER 22 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 11 AM EDT SAT AUG 14 2004 AIRCRAFT...RADAR AND SURFACE OBSERVATIONS SHOW THAT THE CENTER OF CHARLEY IS ON THE COAST NEAR MYRTLE BEACH. RECENT FLIGHT LEVEL WINDS FROM THE AIRCRAFT WERE NEAR 90 KT JUST NORTH OF THE CENTER ALONG THE COAST OF SOUTH CAROLINA AND THE SURFACE PRESSURE WAS 989 MB. SO THE WIND IS KEPT AT HURRICANE FORCE AT 15Z. HOWEVER IT IS NOT CLEAR THAT THE FLIGHT LEVEL WINDS ARE REACHING THE SURFACE AS SURFACE OBSERVATIONS NEAR THE STRONG FLIGHT LEVEL WINDS ARE WAY BELOW HURRICANE FORCE. IN ANY CASE...CHARLY WILL SOON WEAKEN BELOW HURRICANE STRENGTH OVER LAND IF IT HAS NOT ALREADY DONE SO. THE INITIAL MOTION IS 025/24. THE TRACK SCENARIO REMAINS THE SAME WITH AMID-LATITUDE TROUGH OVER THE GREAT LAKES MOVING EASTWARD. THE GLOBAL MODELS ARE IN CLOSE AGREEMENT ABOUT A CONTINUED NORTH-NORTHEASTWARD MOTION FOLLOWED BY A TURN TOWARD THE NORTHEAST AFTER 24 HOURS. CHARLEY IS EXPECTED TO GRADUALLY TRANSFORM TO AN EXTRATROPICAL SYSTEM AS IT MOVES FURTHER NORTH.
