Parts of the east coast of Australia are about to be hit with six days of rain, with recently flood-hit areas expected to cop another drenching.
Weatherzone forecasts a prolonged spell of rain and thunderstorms in Queensland and NSW for the next six days.
There is a chance more than 100mm of rain will impact the areas which were recently devastated by flooding.
The forecast map shared by Weatherzone shows an emphasis of rainfall near the Queensland-NSW border.
Speaking to Yahoo News Australia, Weatherzone meteorologist Joel Pippard said from Thursday, a coastal trough will start to brew off the coast of northern NSW.
The coastal trough will link up with an inland trough which is over northern NSW and southern Queensland.
When those two systems meet, rain will fall across that region.
"It looks like on Thursday, mostly the heavy rain will be confined to the northeast of NSW, but also extending a little bit inland and also further south, so Sydney might get a bit of a wet day," Mr Pippard said.
As for southeast Queensland, only a little bit of rain is going to fall on Thursday, Mr Pippard said the heaviest rain for the state will likely be in the southern ranges, near the NSW border.
The Bureau of Meteorology has also predicted rain for days on end.
Mid North Coast to cop worst of rain
Rain can be expected from Thursday until at least Tuesday next week in places like Lismore and Tweed Heads, two areas on Far North Coast of NSW which were gravely impacted by flooding just weeks ago.
The Bureau said the Central Coast, Hunter, Mid North Coast and Northern Rivers regions might see up to 100mm of rain — all areas that remain saturated by the recent spate of torrential rain.
"Monitor warnings as severe thunderstorms with heavy rain are possible which could lead to flash flooding," BoM NSW said on Twitter.
Mr Pippard said the areas in southeast Queensland and Northern Rivers will likely see the rivers rise again, though border towns and surrounds won't be copping the worst of it.
He advises people to keep an eye on the situation up there with the heavier falls, as the ground is "still pretty saturated".
The heaviest rain will be a little further south in NSW over the coming days.
"The heaviest rain is picked for the Mid North Coast, and maybe the Hunter as well," Mr Pippard said.
It's forecast to rain in Sydney through until next Tuesday, the heaviest anticipated day of rainfall should be Friday for the state's capital, with 10 to 25 mm falling.

Queensland's southeast, including Brisbane, also saw devastating flooding earlier in March and a deluge is also expected to hit there in coming days.
The Bureau's Twitter account for Queensland warned people in the southern regions of the state to be prepared for the weather developing in the coming days.
The Gold Coast could see showers on Thursday and then rain for the next six days, while Brisbane might be spared until Friday, but then the rain will set in.
