24MAR22. TROPICAL CYCLONE 21S (CHARLOTTE), LOCATED APPROXIMATELY
412 NM WEST-NORTHWEST OF LEARMONTH, AUSTRALIA, HAS TRACKED SOUTH-
SOUTHWESTWARD AT 06 KNOTS OVER THE PAST SIX HOURS. TC 21S HAS RAPIDLY
WEAKENED OVER THE PAST SIX HOURS UNDER STRONG AND PERSISTENT
NORTHWESTERLY VERTICAL WIND SHEAR (VWS). THE LOW LEVEL CIRCULATION
CENTER (LLCC) HAS BECOME FULLY EXPOSED IN ANIMATED MULTISPECTRAL
SATELLITE IMAGERY (MSI) AND THERE WAS HIGH CONFIDENCE TO THE INITIAL
POSITION. THE INITIAL INTENSITY HAS BEEN LOWERED TO A GENEROUS 35
KNOTS, WITH THE PGTW CURRENT INTENSITY ESTIMATED AT 2.5 (35 KNOTS)
WITH A FINAL-T OF T2.0. ADT WAS AT 2.7 BUT THE RAW ADT WAS DOWN TO
T1.5. ADDITIONALLY A 232305Z SMOS PASS SHOWED WINDS PREDOIMINANTLY OF
30 KNOTS OR LESS AROUND THE SYSTEM. THE SYSTEM HAS TURNED SOUTHWARD
ALONG THE WESTERN PERIPHERY OF A LOW TO MID-LEVEL SUBTROPICAL RIDGE
(STR) AND IS EXPECTED TO ACCELERATE ALONG THE TIGHTENING GRADIENT
BETWEEN THE STR AND AN APPROACHING SUBTROPICAL LOW. THE SYSTEM IS
FORECAST TO CONTINUE TO WEAKEN, TO BELOW WARNING THRESHOLD WITHIN THE
NEXT 12 HOURS. HOWEVER, THE REMNANT CIRCULATION IS EXPECTED TO
CONTINUE TRACKING SOUTHWARD OVER THE NEXT 36 HOURS BEFORE TURNING EAST
TOWARDS THE COAST OF AUSTRALIA BY TAU 48. THE ASSOCIATED WIND FIELD IS
EXPECTED TO EXPAND AS THE SYSTEM BECOMES SUBTROPICAL IN NATURE BY TAU
36. IT IS POSSIBLE THAT THE SYSTEM COULD REINTENSIFY AS A SUBTROPICAL
LOW AFTER TAU 36 WITH WINDS UP TO GALE-FORCE AT TIMES THROUGH THE NEXT
FEW DAYS. 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 240000Z
IS 16 FEET. REFER TO TROPICAL CYCLONE 22S (HALIMA) WARNINGS (WTXS32
PGTW) FOR TWELVE-HOURLY UPDATES.//
