Emergency services are on alert with wild weather expected to hit Tasmania.
The weather bureau has issued a severe weather warning for damaging winds, with gusts of up to 100 kilometres an hour expected in all major population centres.
Hail, thunderstorms and snow are also forecast, mainly in the west and south.
Senior forecaster Tim Bolden says there is a low pressure system south of Tasmania
"We are in a very cold air mass so we are looking at snow getting down to around the 400 metre level," he said.
"We are expecting some hail obviously about the west and south and if you're above the 400 metre level you will see those showers come through with hail."
He says high winds are predicted.
"Further south on Bruny Island and South Arm, I would imagine getting up to 110 kilometres an hour and also up on the Tasman Peninsula getting up to 110 kilometres an hour," he said.
The weather bureau says Cape Grim has already recorded a gust of 117 kilometres an hour and Flinders Island has recorded winds of 91 kilometres an hour.
The State Emergency Service and Tasmania Police are advising people to secure loose items and to stay clear of fallen power lines.
In Hobart, the Salamanca markets have been closed early as a precaution.
The Hobart City Council says it will partly reimburse stall holders.
