Tasmanians are being told to prepare for the most dangerous fire conditions so far this bushfire season, with high temperatures and strong winds to hit the state.
The fire danger rating in the south and southeast will reach severe levels on Thursday, the Tasmania Fire Service has warned.
Temperatures are forecast to peak in the mid-30s across the island, with Hobart expected to reach 30C.
"These are the most dangerous fire weather conditions forecast so far this bushfire season and any fires that start will be difficult to control," Deputy Chief Officer Bruce Byatt said on Wednesday.
A 24-hour total fire ban has been declared for the north and south from 2am on Thursday, with landowners told to put out any fires before then.
Dry winds of 60-70km/h are forecast, but relief from the hot weather is expected on Thursday afternoon when a cold front crosses the state.
Bushfires in October threatened shacks in the Central Highlands and authorities are bracing for a tough summer season.
"The long-range forecasts are telling us that this fire season is notionally worse than what we experienced last year for that north and east-coast area," Mr Byatt said.
"Certainly the fires that have occurred in New South Wales and Queensland are a reminder to us about people having their fire plans in place."
Parts of Tasmania were last summer ravaged by several larges blazes which burned three per cent of the island.
