The Bureau of Meteorology's Helen Kirkup warned significant snowfall and potentially damaging winds were expected across the alpine region with blizzard like conditions and low visibility likely.

She said snow could fall above 600m in NSW's south west, with towns like Tumbarumba expected to receive a dusting.

Temperatures are expected to be significantly below average across Victoria, while a wind chill factor from strong winds in the Snowy Mountains and South West Slopes will make the region's low temperatures feel even colder.

Roads and Maritime Service's acting director of operations, Jonathon Crocker, warned residents and travellers of changed traffic condition due to heavy snowfall and icy conditions.

"Snow and black ice create additional road hazards and motorists should reduce speed, limit braking, use daytime driving lights and keep an increased distance between cars," he said.

"[Motorists] are advised to delay travel unless necessary, check the road conditions before travelling, take additional caution and drive to the conditions."

In Albury-Wodonga, the bureau has forecast a rainy Saturday, with a maximum temperature of 11 degrees and minimum of two degrees.

On Sunday a minimum of zero predicted in Border cities, while temperature are expected to drop to a minimum of -7 in Falls Creek.
