A total fire ban has been issued for all northern and southern municipalities on Thursday ahead of severe weather conditions.
The Tasmania Fire Service is urging residents to be prepared, with hot temperatures, low humidity and damaging winds expected.
Strong northwesterly winds are expected to bring speeds of 60-70 km/h and peak gusts of 90-100 km/h, although higher speeds are possible in elevated areas.
In the state's East maximum temperatures are predicted to be about 15 degrees above average.
A state maximum of 35 degrees is forecast for several locations in the east and southeast.
Hobart is expected to reach a top of 33 °C before a dramatic cool change in the afternoon.
Deputy Chief Officer Bruce Byatt said landowners with fires already burning or fires they have recently had on their property, must ensure they are properly extinguished on Wednesday.
"These are the most dangerous fire weather conditions forecast so far this bushfire season and any fires that start will be difficult to control," he said.
"The bushfire situation interstate, particularly in New South Wales, has demonstrated the impact bushfires can have on communities and is a stark reminder about the dangers of fire and the importance of being prepared, and having a plan.
"Have a discussion with your family about what you will do if a bushfire threatens your home, and get to know the bushfire alert levels so you understand the warnings the fire service provides during an incident.
"Waiting for a bushfire to start in your area is too late to make a plan."
The 24-hour fire ban will commence at 2am Thursday, November 21 meaning no fires can be lit in the open air - including incinerators, burn offs, campfires, fire pots and wood-fuelled barbecues.
The total fire ban will be in effect in the areas:
North: Break O'Day, Dorset, George Town, Launceston, Meander Valley, Northern Midlands, West Tamar and Flinders.
South: Brighton, Central Highlands, Clarence, Derwent Valley, Glamorgan-Spring Bay, Glenorchy, Hobart, Huon Valley, Kingborough, Sorell, Southern Midlands and Tasman.
Mr Byatt said immediately reporting fires increased the likelihood of containing them quickly.
