Rainfalls from 100-140mm have been recorded in Gippsland over the weekend.

Swollen rivers are continuing to rise, but the Bureau of Meteorology says the rain eased to showers on Sunday in western Gippsland and was moving east.

The flood threat should now not exceed mild to moderate.

The State Emergency Service (SES) warned on Sunday that moderate flooding was still possible in the Snowy and Mitchell River catchments.

The SES has issued flood warnings for six Gippsland rivers and warns that moderate flooding of the Mitchell River is possible later on Sunday, while the Snowy, near Orbost, should peak on Monday.

The Tambo River at Metung and the Latrobe River at Traralgon are classed as moderate flood risks, while the Buchan River at Lakes Entrance and the Tanjil River at Moe both have a minor chance of flooding.

Gippsland was buffeted with winds up to 120 km/h on Sunday, with stronger gusts over Bass Strait.

Snow has fallen at Mount Hotham, in the north-east Victorian high country, with temperatures far below the November average.

Just a week before the start of summer, the weekend cold snap brought snow to the Blue Mountains.

That extended south, with heavy snow falling in the south-east NSW mountain ranges and across the border into Victoria.
