Lightning is being blamed for at least five scrub fires that started in far west NSW yesterday.
The Rural Fire Service says three fires are contained on Langwell station, south of Broken Hill, and there are three more on stations between Broken Hill and Menindee.
Acting Manager with the RFS Bill Britt says rain helped get the fires under control, but others may have started.
"Pretty much everything's contained if not out," he said.
"But we've had a lot of lightning, basically from the Menindee-Ivanhoe road right up to North Little Topar, we've had a big band of lightning go up through there so we're waiting to see what today brings."
Inspector Britt says rain helped put out some of the fires.
"Rain helped us with the one just out of Menindee, on the Wilcannia road, the crews got there but they got a shower of rain on it," he said.
"The other three, they rounded those up but they're just going to wait and see what happens today as the heat starts to pick up."
Essential Energy crews are at Sunset Strip this morning, to see what caused a power outage overnight.
Around 160 houses at Sunset Strip are without power, and another 16 rural households near Menindee.
