"There are no further severe weather warnings currently. We do still have flood warnings for several catchments."
Snow that's fallen in the state is also expected to melt over the next few days which will fill up catchments, Mr Louis said.

Tasmanian Premier Jeremy Rockliff said teams would assess damage caused by the storms and work with local government to support residents.
"But also, we will ask our federal government if it comes to that threshold around disaster relief," he told ABC TV on Tuesday.
