Severe wind warning
A severe weather warning sparked a warning of increased fire danger across Tasmania.
The TFS has issued a warning that the Flinders Group, North East, East Coast and Southern areas will be affected for short periods throughout the day.
The TFS says strong winds, dry air and warmer conditions will see danger ratings range from High to Very High in these areas.
Property owners are urged to refrain from lighting fires during the adverse conditions, as some areas remain dry after recent rainfalls.
The Bureau of Meteorology has issued a Severe Weather Warning for damaging winds in the Furneaux Islands, North East, Western, Central Plateau, Midlands, East Coast, Upper Derwent Valley and South East forecast districts.
Winds around 60 km/h with peak gusts of around 110 km/h are forecast.
The Bureau says in the 2 hours to 5:30am, gusts of 128 km/h were recorded at Hartz Mountains, 120km/h at Scotts Peak and 111km/h on Mt Wellington.
Bushfire season preparation
The TFS is advising land owners that now is the ideal time to reduce bushfire fuel on their properties, despite recent rain.
TFS Chief Officer Mike Brown says home which are prepared are more likely to survive bushfires.
"A defendable space makes it much easier to defend your home," he says.
"If you choose not to stay, a defendable space will help firefighters protect your home, or may even protect your home if firefighters cannot reach it."
However with the current fire danger warning, owners are advised not to light fires.
Land owners planning to conduct burns should check their council's environmental policies and register their intention with the TFS on 1800 000 699.
