Subtropical Depression TWENTY-TWO


ZCZC MIATCDAT2 ALL
TTAA00 KNHC DDHHMM CCA
SUBTROPICAL DEPRESSION TWENTY-TWO DISCUSSION NUMBER   3...CORRECTED
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
11 PM EDT SAT OCT 08 2005

...CORRECTED FOR SUBTROPICAL NOT TROPICAL...AND LAST ADVISORY...
 
SATELLITE IMAGERY THIS EVENING INDICATES THAT THE DEPRESSION IS NO
LONGER PRODUCING ANY DEEP CONVECTION... AND WHAT CONVECTION THERE
HAD BEEN EARLIER THIS EVENING WAS NOT AT ALL ORGANIZED ABOUT THE
LOW LEVEL CENTER... WHICH IS NOW COMPLETELY EXPOSED. THEREFORE...
THE SYSTEM NO LONGER HAS THE CHARACTERISTICS OF EITHER A
SUBTROPICAL OR TROPICAL CYCLONE...  AND SO THIS WILL BE THE LAST
ADVISORY. THE DEMISE OF THE DEPRESSION HAS BEEN BROUGHT ON BY
STRONG EASTERLY SHEAR ON THE NORTHERN PERIPHERY OF THE LARGE
MID/UPPER-LEVEL LOW TO ITS SOUTH. THIS SHEAR IS NOT FORECAST TO
ABATE ANY TIME SOON... SO REGENERATION APPEARS UNLIKELY... BUT THE
REMANT LOW WILL BE MONITORED FOR THE SEEMINGLY REMOTE POSSIBILITY
OF DEVELOPING NEW CONVECTION.

THE TRACK FORECAST ASSUMES THE SYSTEM WILL REMAIN A SHALLOW REMNANT
LOW AND ANTICIPATES A GENERAL WEST-NORTHWESTWARD MOTION... IN THE
LOW LEVEL FLOW AROUND THE SOUTHWESTERN PERIPHERY OF HIGH PRESSURE
OVER THE NORTH-CENTRAL ATLANTIC... FOR THE NEXT TWO TO THREE DAYS
UNTIL THE LOW DISSIPATES.

ADDITIONAL INFORMATION ON THE THIS SYSTEM CAN BE FOUND IN HIGH SEAS
FORECASTS ISSUED BY THE NATIONAL WEATHER SERVICE...UNDER AWIPS
HEADER NFDHSFAT1 AND WMO HEADER FZNT01 KWBC.
