South Indian Ocean

>>> There’s an area of disturbed weather being referred to as Invest 99S, which is located approximately 285 NM east-southeast of Diego Garcia.

Animated multi-spectral imagery depicts a partially obscured low level circulation center with convective banding along the western semicircle. A  301250z ssmis pass shows disorganized curved banding about an elongated llcc along a west-northwest to east-southeast axis.

environmental analysis reveals a marginally favorable environment for development with moderate poleward upper level outflow, moderate vertical wind shear (15-20 kts), and warm sea surface temperatures (29-30 c).

Out of the deterministic models, navgem is most aggressive with 99S, showing immediate development, but other models are more hesitant, showing gradual organization over the next 24-48 hours. Global models agree on 99S turning slowly southward or southwestward over the next 24-48 hours.

Maximum sustained surface winds are estimated at 18 to 23 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours remains low.
