ZCZC MIATCDAT1 ALL
TTAA00 KNHC DDHHMM
TROPICAL STORM TOMAS DISCUSSION NUMBER  40
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   AL212010
500 PM AST SUN NOV 07 2010
 
SATELLITE IMAGES...SURFACE OBSERVATIONS...AND MODEL ANALYSES
INDICATE THAT TOMAS HAS ACQUIRED FRONTAL CHARACTERISTICS.  COLD AIR
STRATOCUMULUS CLOUDS ARE NOW WRAPPING INTO THE INNER-CORE REGION...
AND ANY LINGERING DEEP CLOUDINESS APPEARS MORE ASSOCIATED WITH THE
FRONTAL BOUNDARIES.  THEREFORE...TOMAS IS NO LONGER CONSIDERED A
TROPICAL CYCLONE...AND THIS IS THE LAST ADVISORY ISSUED BY THE
NATIONAL HURRICANE CENTER ON THIS SYSTEM.
 
AN ASCAT PASS AROUND 1500 UTC SHOWED MAXIMUM WINDS IN THE 45-50 KT
RANGE OVER THE SOUTHWESTERN QUADRANT...AND THAT IS THE BASIS FOR
THE INITIAL INTENSITY.  STEADY WEAKENING OF THE POST-TROPICAL
CYCLONE IS EXPECTED DURING THE NEXT FEW DAYS.
 
THE INITIAL MOTION ESTIMATE IS 020/3.  THE POST-TROPICAL CYCLONE IS
FORECAST TO MOVE NORTHEASTWARD OR EAST-NORTHEASTWARD WITH A GRADUAL
INCREASE IN FORWARD SPEED UNTIL IT BECOMES ABSORBED BY A MUCH
LARGER BAROCLINIC LOW OVER THE NORTH ATLANTIC IN 3 TO 4 DAYS.
 
FUTURE INFORMATION ON THIS SYSTEM CAN BE FOUND IN HIGH SEAS
FORECASTS ISSUED BY THE TROPICAL ANALYSIS AND FORECAST BRANCH...
UNDER AWIPS HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.
