The weather bureau is warning people in north-eastern Victoria and Gippsland to prepare for the possibility of heavy rain and flooding over the next five days.
A weather system is moving from south from New South Wales towards Gippsland and is now centred over Albury.
Flood watches have already been issued for North East Victoria, including the Upper Murray, Mitta Mitta, Kiewa, Ovens and King catchments.
Flood watches are also in place for Melbourne, the Barwon River, the Goulburn and Broken Rivers and for all of Gippsland.
Andy Kemp from the weather bureau at East Sale says people should be aware that big rainfall totals are expected across the region.
"(In the area from) Orbost to Moe and up to the hills, 100 millimetres, could be as much as 150 millimetres," he said.
Stuart Beales from the State Emergency Service (SES) says farmers should start moving their stock to high ground and people should prepare their properties and avoid flood waters.
"We're looking at a very hard and fast system which is going to dump potentially between anywhere from 100 to 200 millimetres of rain in a three-day period, which is going to lead to some, what we believe will be riverine and heavy flash flooding."
