Northern parts of Victoria could experience a new flash flooding threat with more rain and thunderstorms expected just as the Murray River peaks at Echuca.
Many towns are on track to experience their wettest October on record, with between 30 millimetres to 60mm predicted to fall in the next day.
There is major flooding in Echuca with the peak expected later on Monday, where dozens of houses built along the banks of the Murray have been swallowed up by water.
