202100Z POSITION NEAR 9.1S 93.3E.
TROPICAL CYCLONE (TC) 03S (BERTIE), LOCATED APPROXIMATELY 295 NM
NORTHWEST OF COCOS ISLANDS, HAS TRACKED SOUTH-SOUTHWESTWARD AT 03
KNOTS OVER THE PAST SIX HOURS. DURING THE NEXT 48 HOURS, TC 03S IS
FORECAST TO TRACK POLEWARD AROUND THE WESTERN PERIPHERY OF A LOW TO
MID LEVEL ANTICYCLONE CENTERED BETWEEN NORTHWEST AUSTRALIA AND SUMA-
TRA. THE INTENSITY OF TC 03S WILL INCREASE SLOWLY DUE TO LACK OF
SUBSTANTIAL OUTFLOW AND HIGHER VERTICAL WIND SHEAR POLEWARD OF THE
SYSTEM. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 201800Z IS 24 FEET. NEXT

REMARKS:
222100Z POSITION NEAR 12.3S 90.2E.
TROPICAL CYCLONE (TC) 03S (BERTIE), LOCATED APPROXIMATELY 390 NM WEST
OF THE COCOS ISLANDS, HAS TRACKED SOUTHWESTWARD AT 04 KNOTS OVER THE
PAST SIX HOURS. OVER THE NEXT 24 HOURS, TC 03S WILL CONTINUE ITS SLOW
TRACK TO THE SOUTHWEST UNDER THE WEAK STEERING INFLUENCE OF A MID-
LEVEL ANTICYCLONE ANCHORED TO THE EAST. BEYOND TAU 24, THE STEERING
INFLUENCE WILL SHIFT TO THE EQUATORWARD PERIPHERY OF A TRANSIENT MID-
LATITUDE ANTICYCLONE, CAUSING THE SYSTEM TO SHIFT TO A MORE WESTWARD
TRACK. IN THE INTERIM, THE SYSTEM WILL MAINTAIN ITS CURRENT INTENSITY
BUT THEN BEGIN TO WEAKEN AS IT ENCOUNTERS STRONGER VERTICAL WIND
SHEAR AND BEGINS TO ENTRAIN DRIER AIR IN THE MID LEVELS. MAXIMUM
SIGNIFICANT WAVE HEIGHT AT 221800Z IS 39 FEET. NEXT WARNINGS AT
230900Z AND 232100Z.//

REMARKS:
240900Z POSITION NEAR 14.7S 89.8E.
TROPICAL CYCLONE (TC) 03S (BERTIE), LOCATED APPROXIMATELY 435 NM
WEST-SOUTHWEST OF THE COCOS ISLANDS, HAS TRACKED SOUTHWARD AT 03
KNOTS OVER THE PAST SIX HOURS. TC 03S WILL TRANSITION TO A WESTWARD
TRACK OVER THE NEXT 24 HOURS AS A SUBTROPICAL RIDGE BUILDS POLEWARD
OF THE SYSTEM. THE CYCLONE WILL STEADILY WEAKEN AS IT MOVES INTO AN
ENVIRONMENT OF INCREASED VERTICAL WIND SHEAR AND LOWER SEA SURFACE
TEMPERATURES. MAXIMUM SIGNIFICANT WAVE HEIGHT AT 240600Z IS 45 FEET.
