The blaze broke out on private property behind Commonwealth Avenue in Littleton around 1.20pm on Thursday and with heatwave conditions crew quickly rushed to the scene.

RFS Chifley/Lithgow Team Operation Officer Gary Hansen said the nine-hectare fire was under control, however, winds were predicted to pick up in the region from 10.30am on Friday.

Currently there are nine RFS trucks on site and 32 firefighters who are working on “securing the edges” of the fire before the winds pick up.

Another worry for crews is the large trees that have been impacted or burnt during yesterday’s fire.

“The concern is that if they fall outside then we have a new fire,” he said.

Mr Hansen said because some of the trees were now structurally unsound and could fall without notice, that this presented a risk to firefighters’ safety.

Nearby resident have been urged to remain vigilant due to the increasing wind speed.

“Be vigilant and keep monitoring the fire, the winds will pick up in an hour,” he said.

“Monitor any embers outside the fire’s edge and also the trees that have been compromised.”

Firefighters who were on scene yesterday have been praised for their efforts is saving telecommunication assets located within the bush.

“There was a telecommunications tower up there which powers telephone, radio and television,” Mr Hansen said.

“We tasked crews up there to ensure they were protected.”

Meanwhile, firefighters remain on scene at a second bushfire in the Lithgow region, with a blaze igniting in remote bushland at Wolgan Valley on Thursday afternoon.

The three-hectare fire is burning on top of the escarpment and remote area firefighters remain on scene along with two water-bombing aircraft.

“National Parks are looking after that one with the help of Forestry and the RFS,” Mr Hansen said.

A lightning strike is the suspected cause of this fire as a number of strikes were recorded in the region during a brief storm on Thursday afternoon.

The Wolgan Valley fire is listed as ‘being controlled’ by the NSW RFS.
