TROPICAL CYCLONE (TC) 15S (EMMA), LOCATED APPROXIMATELY 160 NM WEST-
SOUTHWEST OF PORT HEDLAND, AUSTRALIA HAS TRACKED SOUTHWARD AT 12
KNOTS OVER THE PAST SIX HOURS. THE CONVECTION ASSOCIATED WITH TC 15S

15S WILL CONTINUE TO DISSIPATE UNDER THE INFLUENCE OF THE HIGH VERTI-
CAL WIND SHEAR ENVIRONMENT AND THE EFFECTS OF LAND. THIS IS THE FINAL
WARNING ON THIS SYSTEM BY THE JOINT TYPHOON WARNING CENTER (NAVPAC-
METOCCEN). THE SYSTEM WILL BE CLOSELY MONITORED FOR SIGNS OF REGENER-
ATION. REFER TO TROPICAL CYCLONE 14S (CARINA) WARNINGS (WTXS31 PGTW)
