A severe weather warning remains in place in Tasmania, with expectations of damaging westerly winds overnight.
Some roads in the Central Highlands are covered in snow to seven centimetres, and accessible only to four wheel drives.
The weather bureau says winds are expected to exceed more than 100 kilometres an hour again tomorrow.
Malcolm Riley from the bureau says the low pressure system will intensify.
"We have the severe weather warning out for gusts up to 120 kilometres an hour which are damaging in anyone's books," he said.
"That severe weather warning covers the whole state and really the way the situation is that it looks as though the strongest winds will be probably be going through overnight."
Snow is expected to fall to the 500 metre mark.
Emergency services are on standby and regional crews are also prepared to step up.
The SES is warning homeowners to secure outdoor furniture and other items.
