REMARKS:
110900Z POSITION NEAR 21.8S 119.9E.
11DEC20. TROPICAL CYCLONE (TC) 03S (THREE), LOCATED APPROXIMATELY 53
NM SOUTH-SOUTHEAST OF PORT HEDLAND, AUSTRALIA, HAS TRACKED
SOUTHEASTWARD AT 24 KNOTS OVER THE PAST SIX HOURS. ANIMATED ENHANCED 
INFRARED SATELLITE IMAGERY INDICATES THAT TC 03S MADE LANDFALL AT 
11/03Z, APPROXIMATELY 34NM WEST OF PORT HEDLAND, AND HAS SLOWLY 
WEAKENED AND TRACKED INLAND OVER THE PAST FEW HOURS. MAXIMUM SURFACE 
WINDS (10-MINUTE AVERAGE) AT PORT HEDLAND WERE 38 KNOTS GUSTING TO 
49 KNOTS WITH MINIMUM SLP NEAR 994MB. RADAR IMAGERY NOW DEPICTS 
CONVECTIVE BANDING WRAPPING INTO A BROAD LOW-LEVEL CIRCULATION 
CENTER, WHICH SUPPORTS THE INITIAL INTENSITY ASSESSMENT OF 35 KNOTS 
AND INITIAL POSITION WITH FAIR CONFIDENCE. TC 03S IS FORECAST TO 
QUICKLY TRACK SOUTHEASTWARD UNDER THE COMBINED STEERING INFLUENCE OF 
A DEEP TROUGH TO THE SOUTHWEST AND A SUBTROPICAL RIDGE TO THE 
NORTHEAST. TC 03S WILL WEAKEN GRADUALLY AND SHOULD DISSIPATE BY TAU 
12 WELL INLAND. NUMERICAL MODEL GUIDANCE IS IN TIGHT AGREEMENT 
LENDING HIGH CONFIDENCE TO THE JTWC FORECAST TRACK. 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. REFER TO TROPICAL CYCLONE 02S (BONGOYO) FINAL WARNING 
(WTXS31 PGTW).//
