There’s a tropical disturbance being referred to as Invest 93S…which is located approximately 375 NM south of Christmas Island

According to the JTWC…animated multi-spectral satellite imagery shows deep banding wrapping into the low level circulation center. In addition, there is broad, deep convection within the central and northern peripheries of the system.

Environmental analysis indicates favorable conditions for development to include fair poleward outflow, low (10-15 knot) vertical wind shear, and very warm sea surface temperatures.

Global models are in agreement that the invest 93S is a compact system that will track west-southwest slowly intensifying over the next 24-48 hours.

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 remains high.
