First tropical cyclone of the season brewing over Coco Islands

The first tropical cyclone of the season could be forming in Australian waters but experts say it could come and go without hitting land.

The Bureau of Meteorology (BoM) is monitoring a low pressure system that may develop into a tropical cyclone inside Australia's area of responsibility in the coming days.

The system reaches tropical cyclone strength, it will become the first tropical cyclone of our 2020/21 season and be named Imogen.

"The BoM are monitoring a tropical load that's in the western region, it's fairly far away from Australia at the moment," BoM meteorologist Joel Pippard told nine.com.au.

"At the moment it's a cluster of thunderstorms, that is expected to gain a bit of structure over the next 24 to 72 hours."

"There is a small chance it will turn into a tropical cyclone."

The Australian tropical cyclone season runs from November until April although the first one doesn't usually develop until mid-to-late December.

Australia has an average of 12 cyclones during the cyclone season however of those only about four make landfall.

"There's absolutely no threat to the mainland but the Coco Islands might get increased winds and rains," Mr Pippard said.

But before panicking, there are a few important things to know about this system. Firstly, it's located way out in the Indian Ocean.

On Wednesday morning, the low was around 2,700 km to the northwest of the Australian mainland, out past the Cocos (Keeling) Islands.

Forecast models suggest the system will move south and then west away from our continent.

In its latest outlook, the system had between a five and 20 per cent chance of becoming a tropical cyclone on Thursday or Friday.
