South Indian Ocean

>>> There’s an area of disturbed weather, being referred to as Invest 98S…which is located approximately 362 NM west-northwest of Cocos Islands, Australia

Animated IR satellite imagery shows deep convection sheared to the southwest of a consolidated low level circulation.

Environmental analysis indicates marginally favorable conditions for development with moderate to strong (20-30 knot) vertical wind shear offset by strong divergence aloft and warm sea surface temperatures.

Global models are in good agreement that invest 98S will track slowly to the west and slightly intensify over the next 24-48 hours.

Maximum sustained surface winds are estimated at 23 to 28 knots.

The potential for the development remains low.
