Victorians and Tasmanians are being warned to prepare for a surge of wet weather over the next 72 hours, with flooding expected across the states.
Victoria has been put on notice for a major flood emergency, with up to 100mm of rain likely to fall in some areas north of the Dividing Range and up to 50mm of rain in Melbourne, coupled with wild winds of gusts up to 100km/h.
The amount of rain forecast is expected to have the potential to cause significant damage, with the state's water catchments already full.

The Thomson Dam in West Gippsland is expected to spill for the first time in 30 years.
Fears of landslide caused by the rain has led to people in Bogong Village and Falls Creek in Victoria's Alpine region being told to leave the area by midday.
Manager of the Diana Alpine Lodge in Falls Creek, Lisa Logan, has told 3AW one lane on the only road out of the area is already blocked due to a slow-moving landslide.
"If this rain comes through it's more likely to take out a lot more dirt and trees, and then it'll be completely covering the road and it could take some time for them to clear it," she told Neil Mitchell.
"There's only one road in at the moment. The other road out of Falls Creek is still closed due to snow."
Logan said the road actually collapsed due to heavy rain fall 20 years ago.
Some regional communities are being warned that they could be isolated for up to 72 hours due to flooding.
The Bureau of Meteorology is forecasting a possible rainfall range of 45 to 70mm tomorrow, while Melbourne's wettest October day on record - on October 31, 2010 - saw 61.4mm of rain fall.
However, Weatherzone is predicting that Melbourne will only see closer to 45mm of rain fall tomorrow.
