Two-thirds of Australia is about to be smashed by drenching rains as the stark reality of a cold and wet La Nina summer sinks in.
Another round of rain and storms is on the way for central and eastern Australia with the potential for further flooding.
Two tropical forces are swirling over the continent and their combination is set to bring widespread rainfall over the eastern two-thirds of the country for the rest of the week.
Tropical Cyclone Paddy, the first of the 2021-2022 season, formed near Christmas Island on Monday.
While the Bureau of Meteorology has said it doesn’t pose an immediate threat to the mainland or any offshore communities, Paddy is pumping cloud and humidity into Central Australia.
At the same time, a large cloud mass has been sitting over Australia’s east, bringing humid and unsettled weather.
The weather bureau is warning that more rain could worsen the flood conditions in NSW and potentially flood parts of South Australia and Victoria.
Moderate to large rainfalls are forecast to build over eastern Australia over the rest of the week, with Tasmania the exception.
A low pressure system will deepen over the southeast from Wednesday, tracking towards southern NSW, the ACT and eastern Victoria.
Widespread wind and storms extending up the east coast are forecast to ease by the weekend, but the bureau is warning resulting floods will last for days if not weeks to come.
Australians are in for more rain and flooding this summer after a sodden spring, following the bureau’s declaration of a La Nina weather event on Tuesday.
The La Nina weather phenomenon, linked to the shifting pattern of sea surface temperatures through the Pacific and Indian Oceans, affects rainfall and temperature variations in Australia.
Typically it is associated with heavier rainfall for eastern, northern and central parts of the country, as well as a higher likelihood of tropical cyclones.
Much of eastern Australia has been lashed over the past two months by heavy rain and thunderstorms, which has flooded the Lachlan River catchment in the NSW central west.
The weather bureau is expected to provide updates on the flood risk in Victoria and NSW later on Wednesday.
