WEST-SOUTHWEST OF COCOS ISLANDS, AUSTRALIA, HAS TRACKED WEST-
NORTHWESTWARD AT 07 KNOTS OVER THE PAST SIX HOURS. ANIMATED

AS STRONG VERTICAL WIND SHEAR HAS DECOUPLED THE ASSOCIATED
CONVECTION SOUTHEASTWARD FROM THE LOW LEVEL CIRCULATION (LLC).
ADDITIONALLY DRY AIR HAS BEGUN TO ENTRAIN FROM THE WEST INTO THE
