There’s a tropical disturbance being referred to as Invest 93S…which is located approximately 310 NM north-northwest of Browse Island, Australia
According to the JTWC…satellite imagery shows deep convection, displaced over the western quadrant of a ragged and elongated low level circulation.
Conditions for development are favorable as invest 93S lies near a divergent quadrant of a col region, providing robust outflow, low (5-15 knot) vertical wind shear and very warm sea surface temperatures.
Global numerical models agree that invest 93S will continue on its west-southwestward track and moderately intensify.
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 is upgraded to medium.
