The Bureau of Meteorology has estimated most of Australia have a 70 per cent chance of seeing more rain in the coming months.

Australians should start bracing for a wet winter as nearly all states are set to be drenched by much higher than average rainfall. 
The Bureau of Meteorology (BoM) has estimated that most of Australia have a 70 per cent chance of seeing more rain in the coming months. 
Australians should also prepare for cooler daytime temperatures but nights are expected to be warmer due to thick cloud cover. 
The only places that will escape the wet weather are parts of Tasmania, coastal NSW, eastern Victoria and south-west Western Australia.

The information has been released on Thursday in BoM’s 2020 Winter Outlook.
BoM’s manager of long-range forecasting, Dr Andrew Watkins, said warmer ocean temperatures would bring on the heavy rain over the next three months.
‘Most areas of mainland Australia are showing a better than 70 per cent chance of having a wetter than average winter,’ he said. 
‘Ocean temperatures in the eastern Indian Ocean are currently warmer than normal, and our models are predicting they will warm further throughout the winter months.
‘When warm sea surface temperatures occur closer to Australia, weather patterns shift towards us too, favouring more cloud and rainfall across the country.’
Within each state, Dr Watkins said people would likely see warmer nights – but urged people to rug up for the days. 
‘Areas with a higher chance of above average rainfall are also looking at increased chances of cooler than average days because they are more likely to have cloud cover and more evaporative cooling in the coming months,’ he said.
Along with the wet weather, Australians should also brace for cooler than average temperatures during the day
‘Conversely, it means our nights are more likely to be warmer than average, because that cloud cover will prevent heat from escaping during the evenings.’
NSW and the ACT will see more rain except for areas within the state’s coastal fringe.
Western parts of NSW will experience colder days than average but those living towards the east coast will see warmer temperatures.
Across Queensland there will be a higher than average rainfall except for areas in the far-north.
Both day and night temperatures will be warmer during the winter.
Victoria will see a higher than average rainfall across the state except for areas in bushfire ravaged East Gippsland – which isn’t estimated to show any change.
Days will be cooler in the state’s west but higher than average in the east.
Tasmania has had a higher than average rainfall over Autumn but this is not expected to last through winter.

South Australia will also see higher levels of rain with residents expecting to see cooler daytime temperatures across the state.
Most of Western Australia will be hit with a heavy downpour as well as cooler temperatures.
The Northern Territory will see higher rainfall in the north and less in the southern areas.
‘As always, it’s important people use the outlooks in conjunction with all of the Bureau’s other tools to make decisions, including the seven-day forecast which will provide details on potential rainfall for the immediate days ahead,’ Dr Watkins said.
