There’s a tropical disturbance being referred to as Invest 97S…which is located approximately 133 NM south of Darwin, Australia
According to the JTWC, local weather observations and satellite analysis place the circulation over the western portion of the top end region of Australia.
Albeit over land, invest 97S is in a favorable atmospheric environment with good poleward outflow and low (10-15 knot) vertical wind shear.
Global models agree that the vortex will track to the east-southeast with the possibility of re-intensification over the Gulf of Carpentaria in approximately 48 hours.
Maximum sustained surface winds are estimated at 20 to 25 knots.
The potential for the development of a significant tropical cyclone within the next 24 hours remains Low.
