There’s a tropical disturbance being referred to as Invest 93S…which is located approximately 398 NM south-southeast of Cocos Islands, Australia.

According to the JTWC…animated multi-spectral satellite imagery depicts weak convection wrapping into a fully exposed low level circulation center (llcc). 

The overall environment is marginal, characterized by favorable warm sea surface temperatures being offset by moderate to high (20-30 knot) vertical wind shear and weak outflow aloft.

Global models continue to show a low probability, but non-zero probability of development of this system to tropical storm intensity. The remnant circulation will continue to remain well defined for the near-term and is expected to transit generally westward.

Maximum sustained surface winds are estimated at 25 to 30 knots.

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