TROPICAL STORM GASTON DISCUSSION NUMBER   9
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT SUN AUG 29 2004

GASTON CONTINUES ITS TREK INLAND OVER SOUTH CAROLINA AND IT SHOULD
BE MOVING INTO NORTH CAROLINA LATER TONIGHT.  THE CYCLONE IS NOW
BARELY OF TROPICAL STORM STRENGTH AND IT IS EXPECTED TO BECOME A
DEPRESSION WITHIN THE NEXT FEW HOURS.  GASTON WILL CONTINUE TO
PRODUCE LOCALLY HEAVY RAINS ALONG/NEAR ITS PATH.

THE MOTION CONTINUES AT AROUND 360/7.  A GRADUAL TURN TO THE
NORTH-NORTHEAST AND NORTHEAST WITH INCREASING FORWARD SPEED IS
PREDICTED...AS THE CYCLONE BEGINS TO FEEL THE INFLUENCE OF A TROUGH
MOVING INTO THE NORTHEASTERN UNITED STATES OVER THE NEXT COUPLE OF
DAYS.  THE SYSTEM IS LIKELY TO LOSE TROPICAL CHARACTERISTICS AS IT
MOVES INTO THE CANADIAN MARITIMES AND THEN GET ABSORBED INTO A
FRONTAL SYSTEM.  HOWEVER...PRIOR TO THIS...THE LARGER CIRCULATION
OF GASTON IS EXPECTED TO ABSORB TROPICAL STORM HERMINE IN THE 48
HOUR TIME FRAME.

SINCE GASTON SHOULD CONTINUE TO WEAKEN OVER LAND...THE REMAINING
TROPICAL STORM WARNING FOR THE COAST OF SOUTH CAROLINA WILL LIKELY
BE DISCONTINUED IN A FEW HOURS.
