The Rural Fire Service (RFS) says it has contained fires near Bourke and Cobar as bans remain in place in the Coonamble, Bogan, Walgett and Warren Shires until 11:59pm on Sunday.

Crews used two motor graders yesterday to create mineral earth containment lines to help bring a blaze under control about 60 kilometres north of Bourke, which so far has affected about 340 hectares.

Firefighters also used a motor grader and bulldozer to contain a 30-hectare fire almost 70 kilometres south west of Cobar. 

The RFS is monitoring both fires.

RFS Far West District Manager, Inspector Brad Lennon, said Cobar and Bourke Shires don't currently have fire bans due to cooler conditions from a southerly front last night.

"But what we are doing is constantly monitoring right across the Far West," Mr Lennon said.

"With that cooler change there were thunderstorms and lightning, so we're actually very mindful of potential other fires over the next few days."

Mr Lennon urged community members to remain vigilant. "Be diligent, and if there is any reason for concern, ring triple zero. We'd rather people call and we find that there's not an incident than they hesitate and hold off, and then we find it being more of a concern."

In the North West Zone, which includes Coonamble, Walgett, Warren and Bogan shires, firefighters had an easier time yesterday.

Acting District Manager, Inspector Luke Robinson, said there were no significant fires start on the day.

One header fire was caused by wind igniting embers in a machine that had already been burnt around five to ten kilometres north of Gulargambone.

The RFS also released a harvest safety alert for Coonamble, Walgett and Warren Shires.

"We issued that because the winds and the temperature humidity we were getting on the ground was meeting that trigger. It was getting quite bad," Mr Robinson said.

"Stop harvesting, observe, have a look at the weather conditions, and just make a decision as to whether you're going to continue and, if you are continuing, what controls you putting in place?

"Keep reviewing that decision as you go."
