Tasmania is set to be hit by a cold snap this week which could deliver snow to elevated suburbs of Hobart.
The low-pressure system is expected to cross the island state on Monday night, bringing rain and "really cold Antarctic air" with it, the Bureau of Meteorology's supervising meteorologist Simon Louis says.
He said snow was forecast as low as 100m in some parts of the state.
Strong icy winds with gusts up to 90km/h are likely from Tuesday evening, with maximum temperatures to drop below 10C across most of the state.
A bushwalker alert has been issued for hazardous conditions in the west and Central Plateau regions.
"Because this is a fairly unusual situation and we're talking about some really cold, windy, wet conditions across the east coast, there is some concern if people are not experienced or not prepared properly and are out walking," Mr Louis said.
"It's potentially going to be some really nasty conditions for them. I would urge anyone that's thinking of going hiking to those locations to make sure they are prepared and definitely follow advice from National Parks."
Drivers are being warned to watch for slippery black ice on roads.
"Even once all this snow and rain has gone through, we expect roads to be quite icy for the morning period for the rest of the week," Mr Louis said.
