REMARKS:
172100Z POSITION NEAR 19.5S 152.0E.
TROPICAL CYCLONE (TC) 20P (TIM), LOCATED APPROXIMATELY 220 NM
SOUTHEAST OF WILLIS ISLAND, AUSTRALIA, HAS TRACKED SOUTHWESTWARD AT
06 KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE (IR)
IMAGERY SHOWS THE LOW LEVEL CIRCULATION CENTER HAS BECOME BROAD AND
UNRAVELED AS WEAK REMNANT CONVECTION CONTINUES TO BE DISPLACED BY
STRONG NORTHERLY VERTICAL WIND SHEAR. THE INITIAL POSITION IS PLACED
WITH POOR CONFIDENCE BASED ON THE IR ANIMATION AND FROM A 171621Z
AMSU-B MICROWAVE PASS. THE INITIAL INTENSITY IS BASED ON THE
OBJECTIVE DVORAK FIX FROM CIMS AS ALL SUBJECTIVE ESTIMATES HAVE
CLASSIFIED THE SYSTEM AS TOO WEAK. SYNOPTIC ANALYSIS INDICATES HIGH
VERTICAL WIND SHEAR AND DRY AIR ENTRAINMENT ARE EXPECTED TO PERSIST
OVER THE SYSTEM. SINCE TC 20P IS NOW CATEGORIZED AS DISSIPATED, 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 171800Z IS 11 FEET.
