Statewide cold snap sends temperatures plummetingThursday September 12, 2013 - 16:08 EST
Tasmania's cold snap is continuing with Liawenee recording minus 7 degrees Celsius overnight.
A cold air mass moving up from the south is behind the cold conditions.
The weather bureau's Glen Perrin says the whole state had a chilly night.
"Temperatures of note include minus 7 degrees at Liawenee and also seen minus 5 degrees at Tunnock which is extremely cold for that area," he said.
"Other temperatures: minus 5 at Butler's Gorge, minus 2 in areas like Bushy Park and Ouse, so it has been a very cold night."
There are dangerous driving conditions on some roads this morning.
"We do have a road weather alert out for really a fair part of the state and, also a frost warning for agricultural folks in the state with those very cold temperatures."
Heavy snow has fallen on the Lyell Highway between Derwent Bridge and Mount Arrowsmith, with police recommending access only to four-wheel-drive vehicles.
