Weather this weekend is expected to remain dry with increasing temperatures and strong north westerly winds.

If these forecast conditions impact the fire ground, RFS' public liasion officer Aaron Howard said fire behaviour would become "erractic".

"The fire will progress substantially, with spotting ahead of the fire front likely to occur to the south, south east, and east," Mr Howard said.

Total fire bans may be put in place as a result of these danger ratings, so locals in the North West region are urged to keep an eye on the daily fire danger ratings and follow the rules accordingly.

Back burning will continue today by both RFS and National Parks and Wildlife crews to try and establish eastern and western containment lines ahead of the main fire front.

The fire has burnt more than 10,000 hectares of the national park, and has progressed south past Scutts Hut to steep and inaccessible terrain and continues to slowly spread in easterly and southerly direction.

Due to this inaccessible terrain, fire crews are unable to maintain a southern containment line and it is likely the fire will continue to progress south over the coming days through the national park.

Today there is a high fire danger rating for the Gunnedah, Tamworth, Liverpool Plains, Gwydir and Inverell local government areas. Narrabri has a very high danger rating.

Luckily, no properties are currently under threat and there is no reported damage to infrastructure or communication facilities.
