Several bushfires that started yesterday north of Broken Hill are expected to come under control soon.
The Rural Fire Service lists four as out of control - at Marrapina, Sanpah, Pimpara Lake and Lake Wallace.
The largest is at Sanpah Station, on the South Australian border, where 800 hectares has been burnt out.
Another nine are listed as being under control, mostly around White Cliffs and Wilcannia.
RFS far west manager Chris Favelle says firefighters have been working all night and most of the fires should be under control soon.
"We have got a number of fires that were started in the lightning activity yesterday afternoon - last night - up north of Broken Hill, which our brigades have been working on overnight," he said.
"This morning they tell me they're just about around all those fires that are still listed as out of control so I'm hopeful that by mid-morning we'll have all those contained."
A forecast for dry thunderstorms later today is worrying the Rural Fire Service.
Supt Favelle has cancelled all existing fire permits in the far west and is hoping no more fires start today.
"The number one thing from our perspective is to ensure there's no additional unnecessary fire ignitions so if people are travelling in the far western areas or they're out working on properties or those sort of things that they take great care to ensure that they don't start additional fires," he said.
Another nine fires are listed as controlled by the Rural Fire Service, mostly around Wilcannia and White Cliffs.
