EXTREME weather in the Maranoa is creating some dangerous fire conditions.

Two fires broke out at Yuleba during the week.

Flames tore through 700 acres of bushland at a property at Yuleba on Tuesday.

Fire brigades from Yuleba, Wallumbilla and Roma worked with volunteers in 43-degree heat to bring the situation under control.

The blaze was started by lightning strikes on Monday afternoon, and smouldered until the following morning, when extreme heat caused a raging fire to ignite.

Property owners Mick and Petra Johnson were alerted to the fire by neighbours who saw smoke.

"My husband was at the saleyards so we tore down there," Mrs Johnson said.

"There was already a water truck there and within half an hour there were trucks, dozers and graders."

Yuleba Rural Fire Brigade second officer Michael Taylor said current weather conditions were very dangerous for fires.

"With the extreme heat and wind, fire could burn across bare concrete at the moment," Mr Taylor said.

On Wednesday 120 acres was burnt in a fire also caused by lightning strikes.

Mrs Johnson said the fire took out most of the last feed available on the Yuleba property.

"It was a lot of the feed we had left," she said.

Mr Taylor said it was the last thing people needed at the moment, as the drought showed little sign of breaking.

"We don't need any harder conditions," he said.
