There’s a tropical disturbance being referred to as Invest 92S…which is located approximately 145 NM east-northeast of east London, South Africa.

The system is currently classified as a subtropical storm, generally characterized as having both tropical and mid-latitude cyclone features.

According to the JTWC…satellite imagery depicts flaring convection in the southern semicircle of a obscured low level circulation center.

The system developed primarily over land but has since moved offshore over warm waters.

The overall environment is favorable for development with low to moderate (10-15 knot) vertical wind shear and good poleward outflow offset by cooler sea surface temperatures.

Global models agree invest 92S will track southeast over the next 72 hours while steadily weakening and undergoing extratropical transition.

Maximum sustained surface winds are estimated at 35 to 40 knots.

The potential for the development of a significant tropical cyclone within the next 24 hours is upgraded to high.
