South Australians are bracing for another day of extreme fire danger, with emergency services warning three out-of-control bushfires could flare in the hot, windy conditions.
Temperatures in Adelaide are expected to reach 42C on Friday, and several regional centres are predicted to top 45C.
Country Fire Service chief officer Mark Jones said the forecast was concerning because existing blazes are yet to be brought under control.
Those bushfires are burning at Miltalie on the Eyre Peninsula, Keilira in the southeast and Ravine on Kangaroo Island.
The Cudlee Creek bushfire that destroyed more than 80 homes in the Adelaide Hills last month had now been contained, Mr Jones noted.
"If you think about the Cudlee Creek fire, it came from one spark," he said.
"The ignition sources are already there.
"There are millions of sparks out there ready to go tomorrow if they break containment lines."
A cool change is expected to sweep across the state throughout the day, but the Bureau of Meteorology says the dangerous conditions may not ease.
"It will be a strong and gusty southwesterly change as it moves across the state, and that does bring a risky period in terms of that fire weather," severe weather forecaster Jon Fischer said.
"Despite the cooler, more humid conditions, another challenging period with that wind change."
