A bush fire east of Narrabri is expected to burn for a number of weeks due to steep terrain, so North West residents may see smoke.
The Kaputar fire continues to spread in all directions under variable winds, and approximately 7800 hectares are already burnt in the Kaputar National Park.
Luckily, no properties are currently under threat.
Two separate fires were started by lightning on Wednesday October 16, which have now combined near the summit of Mount Kaputar.
There are currently about 70 rural fire service trucks on site, along with eight aircrafts and eight heavy plants.
NSW Rural Fire Service (RFS) public liaison officer Aaron Howard said the RFS and National Parks and Wildlife Service crews would continue to back burn today and into the evening establish control lines.
They will also monitor for any breaches outside the national park onto private property.
"It's progressing quite slowly and weather conditions are favourable," Mr Howard said.
As conditions ease into the late afternoon, aircraft are planned to assist with aerial ignition, to burn areas the ground crews are unable to access within the containment lines.
Locals are likely to see smoke over the coming days as back burning and aerial ignition continues.
Landholders in the Cotswold Road, Mount Lindesay Road and Trevallyn Road areas are to remain vigilant and stay up to date using the NSW RFS Website or the Fires Near Me mobile app.
A very high fire danger rating is in place for the Gunnedah and Gwydir shires today, with all fire permits suspended.
The fire ground is likely to see an increase in temperatures & stronger north-westerly winds into the weekend.
