Warmer temperatures are expected this week with very high fire danger for parts of the east coast

The Launceston area is expected to reach 29 degrees on Sunday, with areas further inland like Cressy reaching a maximum of 31.

Tristan Oakley from the Bureau of Meteorology said the weather is starting to warm up ahead of an even warmer day on Monday.

"It's definitely starting to heat up," Mr Oakley said.

"Tomorrow we do have a north-easterly to north-westerly flow over the state with air coming in from the mainland, meaning it'll be quite warm across most of the state.

"Especially in Launceston because it's fairly inland we're expecting temperatures up to 30 degrees, and the Bass Strait Islands we're expecting will get up to 32 degrees."

Mr Oakley said more coastal areas in the North and North West won't reach as extreme temperatures due to the effect of the water.

Severe fire danger is forecast for the Upper Derwent Valley and Southeast forecast districts, very high fire danger is expected in the Western, Central Plateau, Midlands and East Coast districts.

A total fire ban has been declared in the Brighton, Derwent Valley, Hobart, Sorell, Central Highlands, Glamorgan Spring Bay, Huon Valley, Southern Midlands, Clarence, Glenorchy, Kingborough, and Tasman municipalities between 2am Monday January 11 and 2am Tuesday January 12.

TFS southern regional chief Ian Bounds said it is a high risk period for firefighters across the state, with extra crews mobilised in preparation.

"We've been monitoring the approach of this system as it comes closer to Tasmania, and on the advice recevied from the Bureau of Meteorology, what we're expecting to see is significant fire danger ratings increase," Mr Bounds said.

"We're expecting very hot conditions into the mid to high 30's in some areas, very dry conditions as well which is the problem.

"As we progress through the day we'll see those winds increase."

Mr Bounds urged people to ensure any prior fires were completely extinguished ahead of the intense conditions.

"We're also including operational machinery, especially in dry vegetation, we're asking people to cease those operations especially if they're using machinery that might cause a spark or an ignition point, especially around vegetation," he said.

"Tasmanians should stay up to date with what's happening around them, and make sure they follow the guidelines around the total fire ban."

The UV index is expected to be in the Extreme range, up to 11.

Cancer Council Tasmania chief executive Penny Egan said Australia had one of the highest rates of skin cancer in the world due to over exposure to UV from the sun.

"Sun protection is generally required when the UV is 3 and above, in Tasmanian this is from September to April." Ms Egan said.

"Except for those who work outdoors, because UV damage accumulates over time, it is recommended that outdoor workers use sun protection year-round.

Mrs Egan said Tasmanians need to protect themselves by five measures outdoors, including clothing that covers as much skin as possible; broad spectrum, water resistant SPF30+ or greater sunscreen; wearing a hat; wearing polarised sunglasses; and seeking shade from the sun wherever possible, especially during peak UV times.

The RSPCA is urging people to remain vigilant in the warm weather, ensuring animals are adequately protected in warmer weather.

RSPCA stakeholder engagement manager Andrea Dawkins urged people not to leave their animals locked in the car, even if there is a window down for air.

"Cars get extremely hot extremely quickly, and it can be absolutely dangerous," Ms Dawkins said.

"People get extremely worried when they see dogs locked in cars at carparks and it results in a lot of callouts for police.

"Just don't do it."

Ms Dawkins said that pets have strong natural instincts, and that as long as they have a shaded area and plenty of water they will manage during the heat.

"Animals know what to do, they have ways to fend for themselves and as long as they have their basic needs they'll be fine," Ms Dawkins said.

"Leaving bowls of water outside for wildlife is a very compassionate position to take on a hot day."

Mr Oakley said the warm temperatures will start to cool off later in the week.

"It's really just that one day that'll be really hot, there's a cold front that'll fall over the state tomorrow [Monday] night into Tuesday bringing cooler temperatures," Mr Oakley said.

"It's still pretty warm, but won't be as warm, with maximum temperatures expected to be back down around the 21 degree mark for Launceston come Friday.

"It is Tassie, it's pretty common to have all four seasons represented in one week."
