TROPICAL CYCLONE 16P (KEVIN), LOCATED APPROXIMATELY 672 NM SOUTHEAST OF SUVA, FIJI, HAS TRACKED EASTWARD AT 19 KNOTS OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY (MSI) SHOWS THE SYSTEM IS ERODING RAPIDLY AS THE ASSOCIATED CONVECTION IS BECOMING DECOUPLED SOUTHEASTWARD AND THE LOW LEVEL CIRCULaTION IS NOW PARTIALLY EXPOSED. CONTINUOUS DRY AIR ENTRAINMENT FROM THE WEST CAUSED SIGNIFICANT EROSION ALONG THE WESTERN PERIPHERIES. EXAMINATION OF THE HWRF VERTICAL CROSS MODEL DISPLAY REVEALS TC 16P (KEVIN) IS QUITE TILTED AND THE MID-LEVELS ARE NOW VOID OF ALL MOISTURE. ANALYSIS INDICATES THE CYCLONE HAS TRANSITIONED INTO A SUBTROPICAL 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 051200Z IS 30 FEET.// NNNN
