Tropical Depression ISELLE


ZCZC MIATCDEP5 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION ISELLE DISCUSSION NUMBER  15
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL   EP102008
800 PM PDT SAT AUG 16 2008
 
ALL THAT REMAINS OF ISELLE IS AN EXPOSED SWIRL OF CLOUDS WELL
DISPLACED FROM A RAPIDLY DIMINISHING SMALL AREA OF THUNDERSTORMS TO
THE WEST.  CONSEQUENTLY...THE SYSTEM NO LONGER MEETS THE CRITERIA
OF A TROPICAL CYCLONE.  HOWEVER...THERE MAY BE INTERMITTENT PERIODS
OF CONVECTIVE BURSTS DURING THE NEXT FEW DAYS...BUT IT IS BELIEVED
THAT THESE BRIEF EPISODES WILL NOT BE SIGNIFICANT ENOUGH TO
RE-DEVELOP THE REMNANTS OF ISELLE.

THE SYSTEM HAS BEEN DRIFTING NORTHWESTWARD THIS EVENING...HOWEVER
THE DYNAMICAL MODELS SUGGEST THAT A GRADUAL WEST-NORTHWESTWARD
MOTION SHOULD COMMENCE WITHIN THE NEXT 12 TO 24 HOURS. 
AFTERWARD...THIS GENERAL MOTION SHOULD CONTINUE UNTIL THE
CIRCULATION DISSIPATES IN AROUND 4 DAYS...IF NOT SOONER.

THIS IS THE LAST ADVISORY ON ISELLE ISSUED BY THE NATIONAL HURRICANE
CENTER.  FUTURE INFORMATION ON THE REMNANTS OF ISELLE CAN BE FOUND
IN HIGH SEAS FORECASTS ISSUED BY THE NATIONAL WEATHER
SERVICE...UNDER AWIPS HEADER NFDHSFEPI AND WMO HEADER FZPN02 KWBC.
