Hurricane ISIS (Text)

ZCZC MIATCDEP2 ALL
TTAA00 KNHC DDHHMM
TROPICAL DEPRESSION ISIS DISCUSSION NUMBER  36
NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL
8 PM PDT THU SEP 16 2004
 
THE CLOCK IS TICKING ON ISIS...FOR THE SECOND TIME. NO DEEP
CONVECTION FOR ABOUT 18 HOURS. ISIS REMAINS A SWIRL OF STRATUS AND
STRATOCUMULUS CLOUDS. I AM LEAVING THE 30 KTS IN THIS PACKAGE BASED
UPON THE EARLIER QUIKSCAT AND SSM/I OVERPASS INFORMATION. VERTICAL
SHEAR AND COOL SEA SURFACE TEMPERATURES SHOULD PREVENT ANY
SIGNIFICANT COMEBACK FOR THE MOMENT. WITH THE WEST-SOUTHWEST MOTION
THE SHIPS MODEL NOW CALLS FOR A REMNANT LOW OUT TO 120 HRS WITH NO
DISSIPATION. ISIS SHOULD BECOME A REMNANT LOW IN ABOUT 6-12 HOURS IF
NO NEW DEEP CONVECTION DEVELOPS.

THE INITIAL MOTION IS 225/3  LARGE-SCALE MODELS SUGGEST THE CYCLONE
SHOULD DRIFT WEST-SOUTHWESTWARD AND THE FORECAST TRACK FOLLOWS THE
GUIDANCE.
