Firefighters are battling to control a large fire burning in the Dungowan Dam catchment, in difficult steep terrain, and surrounding State Forest.
The fire is listed as advice level and has burnt more than 4000 hectares.
Myles O'Reilly, district manager Liverpool Plains Rural Fire Service, said residents need to keep an eye on the conditions and remain alert.
"We currently have 19 fires running across the declaration area - the Pearson Trail Complex fire is one of those," he said.
"There have been activity overnight but is has been reasonably benign.
"We are expecting that to pick up today and at the moment we are marshalling resources just in case.
Mr O'Reilly said they are gathering intel at the moment, and have also been door-knocking and sending out community bulletins to keep the community aware.
He added that fire behaviour continues to be unpredictable under the present conditions and will likely remain unpredictable over the coming days.
The RFS is warning that under present conditions, it is possible that the fire may reach properties along Ogunbil Road, Back Woolomin Road and Duncan's Creek Road over the next 24 to 48 hours.
Properties south of Trundle Forest Way could also be impacted under strong north or north-westerly winds.
Mr O'Reilly said it is crucial that people have a plan in place, and they need to stick to that plan.
If you see fire approaching your property or your neighbours properties, call 000 immediately.
There is currently a statewide fire ban in place.
