There’s a tropical disturbance being referred to as Invest 99S…which is located approximately 143 NM west of Darwin, Australia, Australia

According to the JTWC…satellite imagery shows a flaring, deep convective burst of a slow, anti-cyclonically turning mass.

Environmental analysis reveals that the invest is in a marginally favorable environment for development, defined by pronounced equatorward outflow, favorable (10-15 knot) vertical wind shear, and warm sea surface temperatures. Surface observations from Pt. Fawcett in the Timor Sea recorded sustained 18 knot northerly winds.

Global models are in agreement regarding the intensification and generally quasi-stationary movement of 99S over the next 24-48 hours.

Maximum sustained surface winds are estimated at 15 to 20 knots.

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