REMARKS:
012100Z POSITION NEAR 28.1S 175.4W.
TROPICAL CYCLONE (TC) 16P (POLA), LOCATED APPROXIMATELY 644 NM SOUTH-
SOUTHWEST OF NIUE, HAS TRACKED EAST-SOUTHEASTWARD AT 09 KNOTS OVER
THE PAST SIX HOURS. ANIMATED ENHANCED INFRARED SATELLITE IMAGERY
SHOWS THE LOW LEVEL CIRCULATION (LLC) HAS BECOME FULLY EXPOSED WITH
THE REMNANT DEEP CONVECTION DISPLACED SOUTHEASTWARD. THE INITIAL
POSITION IS BASED ON THE EXPOSED LLC WITH HIGH CONFIDENCE. THE
INITIAL INTENSITY IS AVERAGED FROM THE DVORAK ESTIMATES OF T2.5/35KTS
FROM PGTW AND T3.0/45KTS AND REFLECTS THE RAPID DECAY. UPPER LEVEL
ANALYSIS INDICATES THAT THE CYCLONE HAS ACCELERATED ON THE POLEWARD
SIDE OF THE STEERING SUBTROPICAL RIDGE TO THE NORTHEAST UNDER STRONG
(GREATER THAN 30KTS) VERTICAL WIND SHEAR. CONCURRENTLY, THE CYCLONE
HAS ENTERED THE PREVAILING WESTERLIES AND NOW UNDERGOING
EXTRA-TROPICAL TRANSITION. IN ADDITION TO CONVECTIVE DECAY, THE
SYSTEM WILL TRANSFORM INTO A STORM-FORCE COLD CORE LOW WITH AN
EXPANDING WIND FIELD BY TAU 12. 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 011800Z IS 20 FEET.//
