222100Z POSITION NEAR 27.7S 162.1W. TROPICAL CYCLONE (TC) 08P (EIGHT), LOCATED APPROXIMATELY 388 NM SOUTH-SOUTHWEST OF TONGA, HAS TRACKED SOUTHEASTWARD AT 35 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY SHOWS THE ASSOCIATED CONVECTION HAS BECOME SEVERELY SHEARED, EXPOSING A RAGGED AND ELONGATED LOW LEVEL CIRCULATION. THE INITIAL POSITION IS BASED ON AN ELLIPTICAL LOW REFLECTIVITY CIRCULATION FEATURE ON THE 221700Z SSMIS MICROWAVE PASS WITH HIGH CONFIDENCE. THE INITIAL INTENSITY IS BASED ON AN OVERALL ASSESSMENT OF OBJECTIVE AND SUBJECTIVE DVORAK ESTIMATES AND FROM RECENT SCATTEROMETRY DATA. ANALYSES INDICATE TC 08P HAS BECOME EXTRA-TROPICAL, CORROBORATED BY THE CIRA/RAMMB AMSU RADIAL/HEIGHT CROSS-SECTION PRODUCT AND THE FSU CYCLONE PHASE DIAGRAM SHOWING AN ASYMMETRIC COLD-CORE LOW PRESSURE SYSTEM. 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. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 221800Z IS 15 FEET.
