TRACKED SOUTHWARD AT 22 KNOTS OVER THE PAST SIX HOURS.
THE SYSTEM HAS BEEN ANALYZED AS SUBTROPICAL. ANIMATED
MULTISPECTRAL SATELLITE IMAGERY DEPICTS AN ASYMMETRIC STRUCTURE
WITH CONVECTIVE ACTIVITY SHEARED POLEWARD AND EASTWARD OF THE
LOW-LEVEL CIRCULATION CENTER. THE CENTER IS POSITIONED NEAR THE

THE SYSTEM WILL CONTINUE SOUTHWARD INTO THE BAROCLINIC ZONE OVER
THE NEXT 12 HRS WHERE SEA SURFACE TEMPERATURES ARE BELOW 24C.
THIS IS THE FINAL WARNING ON THIS SYSTEM BY THE JOINT TYPHOON
WRNCEN PEARL HARBOR HI. THE SYSTEM WILL BE CLOSELY MONITORED FOR
SIGNS OF REGENERATION. MINIMUM CENTRAL PRESSURE AT 240000Z IS 994
