Eastern Australia is set to get a huge dumping of rain, as the threat of another bout of inland flooding increases.
Heavy showers are bearing down on the east coast of the country as a band of rain and storms moved east from central Australia, through to western NSW and southwest Queensland on Tuesday.
By 5pm on Wednesday, the wet weather will extend all the way from southern Queensland to northern Victoria.
Dean Narramore from the Bureau of Meteorology said the band of rain would intensify as it moved east on Tuesday, as it was interacting with tropical moisture coming in from the north and the east.
Across all three states of Queensland, NSW and Victoria, there's a widespread chance of 15 to 30mm of rain and there's a possibility of isolated areas seeing up to 50mm of rain.
Parts of northern NSW and southern Queensland may see severe thunderstorms developing on Wednesday.
Rain will develop in Sydney today and continue on Thursday. Brisbane will see showers for the next two days, while Melbourne will forgo the rain, but endure some cloud.
From Wednesday night to Thursday, showers will "quickly" clear in southeast Queensland and northern NSW.
Central parts of NSW and the mid-north coast could see increased rainfall on Thursday and through to the end of the week.
Flood watch in all three states
Parts of Queensland, Victoria and NSW are all on flood watch as the rain moves east over the coming days.
The biggest threat will be to those communities in inland NSW.
"Now with many flood warnings current right across this area, this additional rainfall will likely lead to renewed river level rises across many rivers across inland NSW," Mr Narramore said on Tuesday afternoon.
"That means we could see inundation of homes properties and businesses and adjacent farmland which poses a threat to stock and animals as well as any crops in the area."
