TROPICAL STORM GASTON DISCUSSION NUMBER  17
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
5 PM EDT TUE AUG 31 2004

ON THE LARGER SCALE...THE SYSTEM IS BEGINNING TO LOOK LESS TROPICAL
AS IT APPEARS HAVE BECOME INVOLVED WITH A FRONTAL CLOUD BAND. 
HOWEVER...WSR-88D RADAR DATA INDICATE THAT THERE IS STILL SOME
CONVECTION WRAPPING AROUND THE CENTER...WHICH IS INDICATIVE
OF A TROPICAL CYCLONE.  HOWEVER...GASTON WILL BE PASSING OVER
SIGNIFICANTLY COOLER WATER SHORTLY AND CONTINUE TO INTERACT WITH
THE FRONT...SO IT SHOULD SOON BE TRANFORMED INTO AN EXTRATROPICAL
GALE.  

THERE HAS BEEN MORE ACCELERATION...AND THE FORWARD SPEED IS NOW NEAR
25 KT.  NUMERICAL GUIDANCE CONTINUES TO DIFFER ON THE FUTURE
FORWARD SPEED BUT AGREE ON SOME ADDITIONAL ACCELERATION AS
GASTON...OR ITS EXTRATROPICAL REMNANT...CONTINUES TO BE CARRIED
EAST-NORTHEASTWARD IN THE MID-LATITUDE WESTERLIES.
