Conditions are easing in Hobart, with a mammoth clean-up underway, following the city's wettest day in nearly 60 years.
The city recorded its wettest day since 1960, with 129mm falling in 24 hours on Friday alongside wind gusts of more than 80km/h.
Mt Wellington recorded 236mm, Leslie Vale 226mm and Grove 160mm, with emergency services receiving nearly 400 calls for help.
A teenage boy had to be winched to safety from a flooded cricket oval at New Norfolk, while a security guard was rescued from a windowless room at the University of Tasmania's Sandy Bay campus as it filled with water.
Two people who tried to drive through flood waters at New Town also had to be pulled to safety.
The deluge forced the Sandy Bay campus to close while the Royal Hobart Hospital shut some beds due to flooding.

SES acting regional manager Andrew Dance says the weather has returned to normal as of Saturday morning, with no requests for assistance since 10.30pm on Friday night.
Some residents had asked for help clearing debris so they could access their homes on Friday night, he told AAP. However, SES crews will move into damage assessment tasks rather than emergency assistance on Saturday, he says.
Energy provider TasNetworks said about 1100 homes remained without power on Saturday morning.
Spokesman Dan Sinkovits said the majority of the outages were in Cygnet and Wattle Grove, with 382 homes without power followed by 220 at Kingston and 149 at Sandy Bay.
"We've got fresh crews on this morning so they're working flat out," he told AAP.
TasNetworks estimates power would be restored by Saturday afternoon, Mr Sinkovits added.
The Insurance Council of Australia has declared damage from the floods a catastrophe, while the RACT expected the cost of the storm among its customers to exceed $1 million after it received more than 400 claims.
Wild weather hits Victoria
Parts of Victoria have been hit by strong winds and deluged by rainfall overnight, with several weeks worth of rain expected in one day after months of drought-like conditions.
Farmers were urged to move their livestock to higher ground ahead of up to 100mm expected to fall in the East Gippsland region on Saturday.
Bureau of Meteorology duty forecaster Michael Efron says rainfall was high in East Gippsland overnight, with Reeves Knob receiving 90mm of rain in the 24 hours to 9am on Saturday.

Mt Baw Baw also received 90mm, while Mt Elizabeth had 89mm, he said.
"In terms of winds we actually saw some incredibly strong winds across alpine parts - Mt Hotham recorded wind gusts of 143km/h at 2am and Falls Creek 130km/h," Mr Efron told AAP on Saturday.
"We still have a severe weather warning current for the far east of the state as well as those alpine locations."
Mr Efron added the conditions were "slowly easing", with weather warnings expected to be cancelled by later on Saturday afternoon.
Bureau of Meteorology senior meteorologist Kevin Parkyn told reporters on Friday the wet conditions were welcome after "three months of almost drought-like conditions".
"The good news is conditions have been very dry up until this point in that part of the world, so the ground should be able to absorb that rain and not cause too many problems."
Widespread falls of up to 40mm were recorded across much of Victoria by Friday afternoon, while Melbourne received more than a month's worth of rain in the space of 36 hours.
