The Bureau of Meteorology has issued a severe weather warning for abnormally high tides and possible flooding in Tasmania's south-east.
The weather is being driven by an intense low pressure system which will continue to strengthen throughout the day, bringing heavy rainfall.
Rachel McInerney from the weather bureau said abnormally high tides could cause flooding in low-lying areas.
"It will be around 5 or 6 o'clock this evening so that's when the greatest risk is," she said.
"That's obviously when we will see a fair amount of rainfall as well. So that will contribute particularly to the Huon and Huonville and that sort of area, which will see potentially some water on the roads with those high tides."
About 10,000 customers in Hobart's southern suburbs were without power for several hours on Sunday morning.
Aurora Energy said the outage had affected customers from Dynnyrne to Bonnet Hill.
A spokeswoman for Aurora said the power went off about 8:00am (AEST) and crews were yet to find the cause.
She said crews in Mount Nelson were investigating residents' reports of a loud bang in the area this morning.
