Strike teams of firefighters will be deployed to high-risk hot spots across Tasmania as authorities impose fire bans across the state.
North and south regions of the island are subject to the bans for both Saturday and Sunday with hot and dry conditions forecast.
"There's some hot weather coming over the weekend with some accompanying winds and the fire danger in some areas is going to be very high to severe," Tasmania Fire Service chief Gavin Freeman told reporters on Friday.
The ban means nobody can light a fire in the open and caution should be used when operating machinery that could throw off sparks.
Temperatures in some parts of Tasmania are expected to reach more than 30C on Saturday, with the heat pushing past 40C on Sunday in the north of the state.
"The grass and fire fuels are curing fairly rapidly so those conditions will carry fire," Mr Freeman said.
"Under the weather that we've got available this weekend fire will develop quickly and spread rapidly."
Authorities have resources at the ready.
"We will have strike teams of firefighters stood up ready to go and in some cases they will be pre-deployed into hot spots," Mr Freeman said.
"We will have aircraft sitting there waiting to fly should a fire start and we have machinery already on stand-by and our incident management teams will be up and operating."
A bushfire burning near the state's central Arthurs Lake district since Wednesday was stopped by crews on Friday and Mr Freeman said a couple of other small blazes will be extinguished before the weekend.
As a precaution the Tasmanian Parks and Wildlife Service will close walking tracks for the weekend in some national parks, including at Freycinet and Douglas-Apsley on the east coast.
Citing public safety, the service also announced the closure of trails on Maria Island and Flinders Island.
