Heavens due to open for East Coast
Tasmania's East Coast is set for a dumping of rain in the next 24 hours, which could bring flash flooding to some regions.
Widespread falls up to 100 millimetres are expected, prompting a severe weather warning from the Bureau of Meteorology.
The low pressure system has already brought isolated thunderstorms and showers to the northeast with St Patricks Head (77 mm) and Gray (64 mm) recording the biggest totals last night.
"We're a little bit concerned about the East Coast particularly those areas that did get heavy falls in the past 24 hours. There's been quite a bit of rain up there in the past few months so the ground and catchment areas are very wet. Any further rain could see quite a bit of runoff," Senior Forecaster Simon Louis said.
St Helens, Swansea, Bicheno, Orford, Fingal and Scamander are the towns most likely to be impacted.
There's a moderate flood warning in place for the South Esk river, a minor flood warning for the North Esk, and a flood watch active for a number of other catchment areas across Tasmania.
