The Bureau of Meteorology (BOM) is predicting widespread falls of between 15mm and 20mm on Wednesday and 35mm and 50mm on Thursday.
That rainfall will result in more pressure on already swollen river systems across the region, most notably the Murray, Campaspe and Edward rivers.
A minor flood warning is in place for the Campaspe River from Barnadown to Rochester.
VicEmergency said minor flooding was occurring along the Campaspe River at Campaspe Weir, with river levels nearing a peak yesterday afternoon.
Despite river levels rising, they are expected to peak below the minor flood level.
As of 3pm Sunday, the Campaspe River in Rochester was 0.65 metres below the minor flood level.
Victoria SES incident controller Mark Cattell said the Campaspe was the river they were keeping a close eye on, along with the impending wet weather.
“The high totals predicted may have an impact,” he said.
“Looking at the Campaspe, the rainfall combined with the fact Lake Eppalock is spilling, we may see moderate or major flood warnings later in the week.
“But currently, there is a minor flood warning in place for the Campaspe River from Barnadown to Rochester.”
The Campaspe River continues to be on the rise in Echuca, with water lapping next to the children’s playground on Campaspe Esplanade.
As of 3pm Sunday, the Murray River in Echuca was 92.59 mAHD, which represented a rise of a metre in the space of 16 days.
The swollen Murray was certainly a popular attraction with visitors at the Port across the weekend.
Across the border in Moama on Friday, the local SES unit spent the afternoon sandbagging the southern corner of Moama Riverside Holiday Park.
Friday also saw a community meeting at Torrumbarry, attended by State Member for Murray Plains Peter Walsh.
The BOM said at 4pm Sunday the Murray River at Torrumbarry Weir may reach 7.7 metres with moderate flooding.
Moderate flooding is occurring at Barham, with the Murray predicted to reach near 6.05m.
Deniliquin and Moulamein are the scenes of minor flooding from the Edward River.
The Edward River at Deniliquin is predicted to hit 6.5m around the middle of this week and 4.9m at Moulamein between October 13-15.
