There’s a tropical disturbance being referred to as Invest 97S…which is located approximately 96 NM east-northeast of Nacala, Mozambique

According to the JTWC…satellite imagery depicts formative banding wrapping into a consolidating low level circulation center (llcc). Additionally, a partial pass depicts swaths of 30 knot winds wrapping into the llcc from the northeast.

Environmental analysis shows invest 97S is positioned near an upper-level low that provides increased outflow and low-moderate (10-20 knot) vertical wind shear.

Global models indicate continued development as the circulation tracks southwestward, with potential landfall in 12 to 24 hours as a limiting factor.

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 is upgraded to high.
