TROPICAL DEPRESSION ISIS DISCUSSION NUMBER  35

2 PM PDT THU SEP 16 2004
 
ISIS REMAINS A CONVECTION SWIRL OF OF STRATUS AND STRATOCUMULUS
CLOUDS WITH NO SIGNIFICANT CONVECTION.  EARLIER QUIKSCAT AND SSM/I
OVERPASSES INDICATED MAXIMUM WINDS OF 30 KT...AND BASED ON THIS THE
CYCLONE IS DOWNGRADED TO A TROPICAL DEPRESSION.  VERTICAL SHEAR AND
COOL SEA SURFACE TEMPERATURES SHOULD PREVENT ANY SIGNIFICANT
COMEBACK FOR THE MOMENT...AS EVEN THE SHIPS MODEL IS NOW CALLING
FOR DISSIPATION IN 24 HOURS.  ISIS SHOULD BECOME A REMNANT LOW IN
24-36 HR...AND THEN DISSIPATE COMPLETELY BY 120 HR.

THE INITIAL MOTION IS A VERY DUBIOUS 205/2.  LARGE-SCALE MODELS
SUGGEST THE CYCLONE SHOULD DRIFT GENERALLY WEST-SOUTHWESTWARD UNTIL
DISSIPATION...AND THE FORECAST TRACK FOLLOWS THE GUIDANCE.
