TC 20S IS BEING STEERED BY A 500 MB RIDGE OVER AUSTRALIA TO THE SOUTHWEST. THIS TRACK WILL BECOME MORE POLEWARD IN RESPONSE TO A WEAKNESS CAUSED BY A MIDLATITUDE TROUGH SOUTH OF WESTERN AUSTRALIA. THE SYSTEM HAS LOST ITS EYE IN BOTH VISIBLE AND ENHANCED IR SATELLITE IM- AGERY. SOME FURTHER GRADUAL WEAKENING IS EXPECTED DUE TO AN IN- CREASING VERTICAL WIND SHEAR ENVIRONMENT TO THE SOUTH. TC 20S IS FORECAST TO MAKE LANDFALL NEAR TAU 36. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 281800Z IS 35 FEET. NEXT WARNINGS AT 290300Z, 290900Z, 291500Z AND 292100Z.//
