An extreme fire warning is in place for vast parts of Queensland today with temperatures set to soar into the record books.
The Queensland Rural Fire Service (QRFS) says heat and strong westerly winds have increased the bushfire risk across southern, central and western Queensland.
Emerald, Longreach and Charleville are all expected to approach 40 degrees today and tomorrow.
QRFS director Peter Varley says with winds of up to 50 kilometres per hour any new fires will be fast-moving and uncontrollable.
"We expect those conditions without any rain will continue to worsen up to Thursday then move closer to the coast," Mr Varley said.
"It's very, very dry at the minute - no moisture in the air.
"That combined with winds particularly from the west because they always tend to be the warmer hot winds, that's what causes the worst fire danger days."
A large fire ignited by dry lightning a week ago is still burning near the Carnarvon National Park.
A dozen firefighters are back-burning today after a large grass fire west of Maryborough in the south east.
The fast moving blaze at North Aramara destroyed an abandoned bus and threatened one home.
The blaze has burnt 20 hectares of bushland.
Senior forecaster Ben Annells says temperatures are likely to head into the history books before a change arrives towards the weekend.
"It's likely we'll see temperature records broken today and tomorrow through many locations out over the interior of the state and even over the Darling Downs as well with that trough moving through tomorrow."
Tony Stroud from the Queensland Fire and Rescue Service (QFRS) says residents should delay any activities which could spark fires.
"Rider mowers hitting a rock, especially in very dry grass can put a spark," he said.
"Graders will spark onto any kind of rock or dozers and once that happens it's really hard for that machine to just turn around and put that fire out.
"They either need to suspend that [activity] or have a fire unit behind them."
