Three adults and two young children have been rescued by helicopter after becoming trapped in floodwaters in Huonville, south-east of Tasmania.

Tasmania Police said the group was stranded on a piece of land bordering the Huon River near Wilmot Road after trying to rescue horses.

The woman, who owns the property, and her children — two young boys under the age of 10 — became stuck first, before her husband and a neighbour tried to use a boat to rescue them.

The water was moving too fast for the group to be rescued by boat, with the helicopter arriving about an hour after the alarm was raised.

"It was very lucky, the neighbour actually saw the lady when she was signalling," Sergeant Andrew Fogarty said.

A low-pressure trough that brought damaging weather to South Australia continued to move south across Tasmania, bringing heavy rain and strong winds.

But the severe weather warning for heavy rainfall and damaging winds in Tasmania has now been cancelled.

Flood warnings were still in place for the South Esk, North Esk, Macquarie, Meander, Huon, Jordan and Derwent Rivers and a flood watch was issued for all river basins.

Strong winds, rainfall lashes state

Hobart recorded 23 millimetres on Thursday night, while 51mm fell at Grove in the Huon Valley and 50mm at Mt Wellington.

The north of the state was lashed by strong winds and rain on Thursday, Fisher River recorded 95mm of rain, Interlaken 91mm and Mt Victoria 88mm.

Bureau of Meteorology (BOM) spokesman Matthew Thomas said the system that battered South Australia had weakened as it moved over Tasmania.

He said 2016 had been a record-breaking year for flood warnings.

"Up until the end of April it was incredibly dry for Tasmania," he said.

"It switched at the start of May and we've had a record number of warnings and there's still three months to go."

The SES received more than 60 requests for assistance across the state, with most in the south.

"Most of the callouts resulted from water inundation from either drains or flooded creeks or rivers," spokesman Brian Edmonds said.

"At this stage the rain has eased and the situation is improving."

A number of roads were closed due to flash flooding throughout the day.

Southern Regional Manager Mark Nelson said the damage was widespread, with calls from Sandy Bay, Montague Bay and Geilston Bay in the Hobart area, as well as Old Beach, Gagebrook and Brighton.

But he said the flooding in the Huon was not as serious as the deluge in July.

"It's not the river-end flooding. This time it's flash flooding, so it's smaller creeks in and around Huonville which have broken their banks and they have gone over roads in places," Mr Nelson said.

About eight homes in the area have been flooded.

TasWater advised people in Huonville to boil their drinking water because the rain is affecting water quality.
