There’s a tropical disturbance being referred to as Invest 90S…which is located approximately 806 NM southeast of Diego Garcia
According to the JTWC, satellite imagery depicts a broad low level circulation with persistent deep convection in the northern and eastern sectors.
Environmental analysis indicates that the invest is in a generally favorable area of development defined by low (5-10 knot) vertical wind shear, warm sea surface temperatures, and fair equatorward outflow.
Global models are in agreement that invest 90S will slowly drift equatorward over the next 24-48 hours with gradual intensification.
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 medium.
