Emergency crews are bracing for possible flooding in southern Tasmania as melted snow runs into an already brimming river system.
The island state has battled more than two days of rough weather including rain, sleet and wind gusts of up to 150km/h which has brought down trees, ripped off roofs, knocked out power supplies, closed roads and sent dangerous projectiles hurtling.
With conditions set to ease late on Thursday, the attention will turn to the Huon River south of Hobart.
"We have a potential flooding situation emerging in the Huon Valley and specifically the Huon River," acting SES director Nick Wilson said.
"The amount of rainfall into the catchment ... together with melting snow will result in minor to moderate flood rises."
Sandbagging has begun, with farmers in the area advised too move stock to high ground.
"Widespread inundation is not likely, no evacuation is likely for Huonville but there might be some localised inundation to a couple of businesses and (a) caravan park if the flood peak is realised," he told reporters.
The Huon River is expected to hit its forecast peak of 4.1m at about 4am (AEST) Friday.
"That peak is likely to be sustained for some time due to the fact the melting snow makes it somewhat unpredictable and also some tide events."
There are less than 10 dwellings on the Huonville esplanade that could be flooded.
Early on Thursday wind speeds through Hobart's CBD reached 113km/h, causing the 10th floor windows of a building to blow in.
It was just a couple of doors away from a business where a brick facade collapsed on Wednesday, injuring a passing pedestrian.
SES regional manager Mark Nelson said crews are facing hazardous conditions as they respond to numerous calls for assistance.
"If you don't have to, don't go out and about ... because there is a lot of flying debris," he warned members of the public.
