Firefighters, aided by waterbombing aircraft, are gaining control of a bushfire which flared up in the NSW Blue Mountains near Glenbrook.
The NSW Rural Fire Service issued a watch-and-act alert in the Mitchells Pass area on Thursday afternoon.
Land crews and an air tanker managed to slow the spread of the fire, which continues to burn aided by northeasterly winds in hilly terrain.
The alert was downgraded to "advice" level at 3pm as firefighters began to gain control.
Farther north, more than 8000 hectares in the Wollemi National Park and Putty State Forest were scorched by a bushfire that could take crews weeks to extinguish.
The Rural Fire Service downgraded the emergency warning on Thursday after severe fire conditions saw the blaze flare out of control.
"I don't think we're out of the woods as far as the fire risk for that particular fire," RFS Deputy Commissioner Rob Rogers told the ABC from RFS headquarters on Thursday.
Total fire bans are in place in five regions of NSW including Illawarra/Shoalhaven, the Southern Ranges, the Central Ranges, North Western and the Northern Slopes.
Mr Rogers said northwest NSW faces a severe fire danger threat.
"We're expecting gusty winds as the change moves up the coast and those winds that were in Victoria move through NSW," he said.
"So we're in for another long day and a lot more firefighting."
