There’s a tropical disturbance being referred to as Invest 15S…which is located approximately 117 NM west-northwest of Wyndham, Australia

According to the JTWC…satellite imagery shows flaring convection wrapping into a broad low-level circulation.

Conditions for re-intensification are favorable with low-moderate (10-20 knot) vertical wind shear, decent poleward outflow, and warm sea surface temperatures…if the remnants of TC 15S tracks into the Indian ocean.

Global numerical models agree that former TC 15S will continue to track southwestward along the northwestern Australian coast and possibly remerge over water after 24 hours.

Maximum sustained surface winds are estimated at 28 to 33 knots.

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