Few sights in Australia are more spectacular than Uluru after rain, as waterfalls cascade down rocky gullies which are normally bone dry.

The last time the area saw decent rain was in October last year, when around 30 mm fell at Yulara in a day. But current models suggest even heavier rain could fall towards the end of Sunday, or more likely, on Monday.

It all depends what happens with the tropical low pressure system currently sitting about 200 kilometres off Western Australia.

"After crossing the coast, the system is expected to move down through the West Australian interior and into central Australia," Weatherzone meteorologist Ben Domensino explains.

"At the moment, that track looks like it will cause heavy rain over the southwest of the Northern Territory, which includes the area where Uluru is located."

Forecast models currently vary on how much rain can be expected, should the moisture-laden system make its way to Central Australia, but the remnants of the tropical low could deliver as much as 100 mm in the Red Centre, some models suggest.

That would be more than enough to generate waterfalls on Uluru, and there could also be some Central Australian flooding. We'll keep you updated.
