REMARKS:
220900Z POSITION NEAR 18.1S 95.5E.
TROPICAL CYCLONE (TC) 24S (JACK), LOCATED APPROXIMATELY 360 NM SOUTH-
SOUTHWEST OF COCOS ISLAND, HAS TRACKED EAST-SOUTHEASTWARD AT 12 KNOTS
OVER THE PAST SIX HOURS. ANIMATED MULTISPECTRAL SATELLITE IMAGERY 
(MSI) REVEALS A FULLY-EXPOSED, ELONGATED AND RAPIDLY-WEAKENED LOW-
LEVEL CIRCULATION CENTER (LLCC). MSI ALSO INDICATES THAT THE LLCC IS 
INTERACTING WITH AN AREA OF STRATOCUMULUS TO THE SOUTH AND, AS SHOWN 
IN THE TOTAL PRECIPITABLE WATER ANIMATION, IS LIKELY INFUSING DRY 
AIR. RECENT SCATTEROMETER DATA PROVIDES SOLID EVIDENCE OF THE RAPID 
WEAKENING OVER THE PAST 12 HOURS. SPECIFICALLY, A 220309Z ASCAT 
IMAGE SHOWS ONLY 20 TO 25 KNOT WINDS OVER THE EASTERN SEMI-CIRCLE 
WHILE A 212324Z WINDSAT IMAGE SHOWED 25 TO 30 KNOT WINDS OVER THE 
NORTHEAST QUADRANT WITH WEAKER WINDS ELSEWHERE. ADDITIONALLY, UPPER-
LEVEL ANALYSIS INDICATES THAT THE LLCC IS EMBEDDED IN THE LEADING 
EDGE OF A DEEP UPPER-LEVEL SHORTWAVE TROUGH WITH STRONG 
NORTHWESTERLY VERTICAL WIND SHEAR. TC 24S IS FORECAST TO TRACK 
SOUTHEASTWARD AND SLOW AS A LOW-LEVEL RIDGE BUILDS TO THE SOUTH BUT 
IS FORECAST TO REMAIN WEAK DUE TO UNFAVORABLE CONDITIONS. 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 220600Z IS 15 
FEET.//
