REMARKS:
272100Z POSITION NEAR 16.6S 137.5E.
TROPICAL CYCLONE (TC) 02S (ALESSIA), LOCATED APPROXIMATELY 462 NM
EAST-SOUTHEAST OF DARWIN, AUSTRALIA, HAS TRACKED SOUTHWARD AT 03
KNOTS OVER THE PAST SIX HOURS. ANIMATED INFRARED SATELLITE IMAGERY
DEPICTS PERSISTENT DEEP CONVECTION OVER THE EASTERN SEMI-CIRCLE OF
A POORLY-DEFINED LOW-LEVEL CIRCULATION CENTER (LLCC). RADAR IMAGERY
FROM MORNINGTON ISLAND INDICATES THAT THE LLCC HAS TRACKED BACK OVER
LAND AND HAS WEAKENED SIGNIFICANTLY. A 271242Z ASCAT IMAGE SHOWS
ONLY 15 TO 25 KNOT WINDS OVER THE EASTERN SEMI-CIRCLE. SURFACE 
OBSERVATIONS LOCATED OVER THE WESTERN SEMI-CIRCLE OF THE SYSTEM 
INDICATE SUSTAINED WINDS LESS THAN 10 KNOTS AND SLP NEAR 1003 MB.
THE INITIAL POSITION IS BASED ON RADAR IMAGERY WITH LOW CONFIDENCE
DUE TO THE LACK OF CONVECTIVE BANDING INTO THE CENTER. THE INITIAL
INTENSITY IS ASSESSED AT 30 KNOTS AND IS BASED ON THE ASCAT DATA.
TC 02S IS DRIFTING SOUTHWARD AND IS EXPECTED TO REMAIN OVER LAND AS 
IT TRACKS WESTWARD UNDER THE LOW-LEVEL SUBTROPICAL RIDGE POSITIONED 
TO THE SOUTH. DYNAMIC MODELS INDICATE SLOW TRACK SPEEDS AND A 
GENERALLY WESTWARD TRACK WITH A LOW PROBABILITY OF TRACKING BACK 
OVER THE GULF OF CARPENTARIA. OVERALL, THERE IS LOW CONFIDENCE IN THE
JTWC FORECAST TRACK DUE TO THE LACK OF CONVECTIVE STRUCTURE AND
WEAK STEERING ENVIRONMENT. 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.//
