A FIRE has broken containment lines in a corner of northwest NSW already ravaged by flames, boosting fears soaring temperatures could ignite a fresh wave of destruction.
Rural Fire Service Commissioner Shane Fitzsimmons said the blaze was threatening some rural homes at the southern end of the Coonabarabran fire front.
"We've seen a run of fire to the south and that has resulted in the Newell Highway again being closed," he said.
"There are some rural properties in that area but we've got some fire trucks and fire crews working on those properties and of course the aircraft and other resources, heavy bulldozers and things, are dispatched to assist as well.
"That fire ran in the order of five to 10 kilometres overnight."

He said firefighters hoped to bring the blaze under control before the worst of the weather hits on Friday.
There are 84 fires burning across the state, with 14 of them uncontained.
A total fire ban is once again in place across much of NSW as a return of hot and windy conditions prompt fears existing fires could get out of control.
The 45,000-hectare blaze in the Warrumbungle National Park, west of Coonabarabran, has so far destroyed 51 properties.
"That fire just actually broke containment lines a little while ago," RFS Deputy Commissioner Rob Rogers said of the blaze at Gowang, which has cut the Newell Highway.
"So we are already seeing conditions flare up already. So people obviously in those areas need to take extreme caution."
Temperatures are expected to soar in many of the worst-affected areas on Friday, with the mercury climbing into the 40s in Sydney.
"When you combine that down south with winds of up to 70km/h ... then pretty well most of NSW, with the exception of the very northeast and northwest, we are going to be looking at very, very tough conditions today," Mr Rogers has told the Seven Network.
"So we really need people to be ready to act their bush survival plan and don't assume someone else has reported a fire."
Prime Minister Julia Gillard visited Coonabarabran yesterday and paid tribute to the bravery and stoicism of residents.
Other notable fires are those at Deans Gap in the Shoalhaven and Yarrabin in the Cooma-Monaro area, which have been burning continuously since threatening properties last week.
