PARTS of Gippsland, already soaked from the wet season, could receive up to 100mm of rain this week.
The Bureau of Meteorology have issued a flood watch for South, West and East Gippsland as a slow high and low pressure system will cause rain in this region for the rest of the week.
The heavy rain will be confined to the Gippsland however the south of the state should get some isolated showers.
There will be no significant rain for the cropping region of northern Victoria.
"There is a deep low pressure system near Sydney and string of high pressure systems near Tasmania and both of those are almost stationary for the rest of the week," said the bureau's senior forecaster Richard Carlyon.
"We are expecting 20 to 50mm each day in Gippsland, by the end of the week we are likely to see some areas accumulate 100mm.
"We've put a flood watch for East and South and West Gippsland.
"There is no warning with the rivers yet, but we anticipate we may need to issue warning by the end of the week," Mr Carlyon said.
Farmers in West and South Gippsland have reported soils and farms are at breaking point with the wet conditions.
Dairy farmer Peter Hanrahan, from Stony Creek near Leongatha, said some producers in his district were in a diabolical situation with the soggy conditions.
"Every day is such a tough slog for them," Mr Hanrahan said.
"If you've had a wet autumn there is nowhere for the water to go."
