A warm, wet winter is forecast for Western Australia's Great Southern, but snow is still expected on the region's highest peaks.
The Stirling and Porongurup ranges, north of Albany, are the only places in Western Australia to regularly record snow in winter.
Bluff Knoll, in the Stirling Range, is the highest peak in southern WA at 1,099 metres, and usually records a few falls each year.
"This air originates from well south of the state, it's very cold, very saturated," Bureau of Meteorology forecaster Jessica Lingard said.
"As it reaches the land, if lifts up when it goes over the ranges and condenses.
"Because it's so cold it condenses straight into ice crystals."
Closer to the ground, the BOM's winter outlook is good news for farmers.
"We're expecting a warmer than average winter … and slightly wetter," Ms Lingard said.
The east of Australia is expecting its first major snowfalls of the year this week as a strong cold front hits the south-east, with the region's higher mountain ranges more conducive to snow.
