There are no active tropical cyclones…although there continues to be an area of disturbed weather in the Indian Ocean

This tropical disturbance is being referred to as Invest 98S, and is located approximately 525 NM north-northwest of Learmonth, Australia.

Satellite imagery shows persistent convection wrapping into a developing low level circulation center.

Upper level analysis indicates this system is in an area of low wind shear, and favorable poleward and equatorward outflow aloft.

Sea surface temperatures are conducive for tropical cyclone formation, and weather models indicate steady development of this area during the next few days.

Maximum sustained winds are estimated to be 25-30 knots.

The JTWC is giving this area a high potential for development into a significant tropical cyclone over the next 24 hours.

Here’s what the global models are showing for potential tracks

According to the Australian Government Bureau of Meteorology (BOM) –

A Tropical Low was located at 8 pm WST near 14.5S 110.6E, that is 910 km north northwest of Exmouth and moving west southwest at 16 kilometers per hour. The system is expected to develop into a tropical cyclone on Wednesday but is not expected to affect the WA mainland in the next 48 hours. On Friday the system will be approaching the far northwest of the state but is then expected to weaken.
