There are no active tropical cyclones…although there’s an area of disturbed weather in the Indian Ocean

This tropical disturbance is being referred to as Invest 98S, and is located approximately 620 NM north of Learmonth, Australia.

Satellite imagery shows a consolidating low level circulation center, with good convective spiral banding…wrapping into the systems center.

Upper level analysis indicates a favorable environment north of a ridge of high pressure, with low to moderately strong (10-15 knot) wind shear…and good poleward outflow supporting thunderstorm activity in the area.

Maximum sustained winds are estimated to be 15-20 knots.

The JTWC is giving this area a low 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 is developing to the south of Indonesia near 11.5S 115E, and is moving southwest. This low is currently weak but conditions are favorable for it to develop over the next few days. Conditions become rapidly unfavorable on Friday and so any development will be short-lived. The risk of this system becoming a tropical cyclone increases to Low from Wednesday. These ratings may be increased if the environment continues to be favorable.

Likelihood of this system being a tropical cyclone in the Western Region on:

Tuesday:  Very Low
Wednesday:  Low
Thursday:  Low

There are no other significant lows in the Western Region and none are forecast to develop over the next few days.
