Yet another round of widespread rainfall is on the way in the east this weekend, while the tropics are set to swelter all the way into next week.

According to the Bureau of Meteorology's Jackson Browne the rain is expected to set in over eastern South Australia, south-west Queensland and western New South Wales today as a trough extends across the country.

"We could see the trifecta of large hail, damaging winds and heavy rainfall," he said.

While severe storms could be in the mix, Mr Browne says they are expected to be less severe than the huge supercell thunderstorms we saw in October.

On Sunday a low pressure system is expected to form and drive more rain, but where exactly it is set to go is still a bit uncertain.

"It has been a bit of a source of forecast frustration," Mr Browne said.

But he is confident it will track somewhere over the north and east of NSW.

On Sunday widespread falls of 25 to 50 millimetres are expected over north-eastern NSW, with heavier falls of 50 to 100 millimetres if you are under one of those severe thunderstorms.

No end in sight

How much rain will hit those catchments currently in flood will largely depend upon where exactly the low goes.

But Mr Browne warned that while some locations might miss out this weekend, with La Nina on our doorstep, these rounds of wet weather are going to keep coming.

"So if it's not this one, it may be the next one, or it might be the third one," he said.

Another round is forecast for next week.

"We've had pretty solid rainfall over the winter months, as well as the very active storm season," Mr Browne said. 

Catchments are sodden and the atmosphere is primed.

"I think people should keep in mind that this flood threat will be with us for the next few months," Mr Browne said.

Many changing warnings are expected over the next few days, so keep up to date in your area at ABC Emergency.

Not your regular build-up

Meanwhile much of the tropical north is forecast to experience heatwave conditions over the weekend and into next week.

It might only be a few degrees warmer than usual, but that will combine with increased moisture to result in oppressive conditions ? hot days followed by warm nights.

Mr Browne says the build-up will be worse than normal. 

"That's coming from an ex-Territorian who did forecasting in Darwin for a good eight years," he said.

"I could see people rolling their eyes, and being like, 'It is always hot in Darwin,' or 'It's the build up' ? but this one will bite differently." 

Mr Browne encouraged people to take care of themselves over the next few days and said staying hydrated was particularly important.

"If you do have access to cooling, like air conditioning, fans, make sure you're using it, make sure you're using it overnight to give your body a chance to recover," he said.
