Hurricane CHARLEY


ZCZC MIATCDAT3 ALL
TTAA00 KNHC DDHHMM
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.
