| #6795 (Received by flhurricane at: 4:51 AM 31.Aug.2004) TCDAT2 TROPICAL STORM GASTON DISCUSSION NUMBER 15 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL 5 AM EDT TUE AUG 31 2004 WSR-88D DATA FROM DOVER DELAWARE SHOWS THAT GASTON STILL HAS A GOOD RADAR SIGNATURE. HOWEVER...SATELLITE IMAGERY SHOWS THAT THE DEEP CONVECTION IS LIMITED IN COVERAGE AND INTENSITY...AND A FRONTAL-LIKE BAND SEEMS TO BE FORMING SOUTHEAST OF THE CENTER. A COMBINATION OF AN APPROACHING BAROCLINIC ZONE AND COLD SEA SURFACE TEMPERATURES SHOULD CAUSE GASTON TO LOSE TROPICAL CHARACTERISTICS IN 24-36 HR. THE INITIAL MOTION IS 060/16. GASTON SHOULD ACCELERATE EAST-NORTHEASTWARD THROUGH THE FORECAST PERIOD AS INDICATED BY ALL GUIDANCE. THERE IS SOME SPREAD IN THE SPEED...AND THE FORECAST SPEED IS A COMPROMISE BETWEEN THE VARIOUS MODELS. FORECASTER BEVEN FORECAST POSITIONS AND MAX WINDS INITIAL 31/0900Z 38.4N 73.8W 35 KT 12HR VT 31/1800Z 40.0N 70.4W 35 KT 24HR VT 01/0600Z 42.3N 64.0W 35 KT...BECOMING EXTRATROPICAL 36HR VT 01/1800Z 45.1N 56.2W 35 KT...EXTRATROPICAL 48HR VT 02/0600Z 48.5N 46.7W 35 KT...EXTRATROPICAL 72HR VT 03/0600Z...ABSORBED BY FRONTAL SYSTEM |
