Properties are under threat and residents have been told it’s too late to leave as a fire burns out of control at Tambaroora, about 270km north-west of Sydney.
Residents at Cranbrook near Dubbo have also been under threat this afternoon, but an earlier emergency warning has been downgraded to a watch and act.
About 48 homes were under threat by the blaze, which was я╗┐sparked by a lighting strike.
“Fire has crossed Hill End Rd. If you are in the area of Alpha Rd, Hill End Rd, Ullamulla Rd & Tambaroora, seek shelter,” NSW RFS said on Twitter.
“If you are in Sallys Flat leave now towards Bathurst. If you are N of Doughertys Junction, leave now towards Mudgee.”
Windy weather was making conditions more difficult for firefighters.
Earlier, an emergency warning was issued for the Cranbrook fire near Dubbo, about 400km north-west of Sydney, and a “shelter now” warning at nearby Toongi.
Just before 8pm, the warning was downgraded to a watch and act, with the RFS urging residents to monitor conditions.
The Cranbrook fire has burnt through 700 hectares.
There is also a watch and act warning for residents living in Burrendong, south-eat of Dubbo.
Dozens of fires continue to burn across the state.
Sydney recorded its hottest day in more than two years, with temperatures set to continue to soar until Wednesday.
NSW Rural Fire Service Commissioner Rob Rogers said earlier they were worried because rain had caused vegetation to grow.
Rogers said parts of NSW haven’t had this level of fire risk in years.я╗┐
“Before the 2019-20 fires, there was nothing out there because it was a drought and just dust,” he said.
“Now there is grass more than a metre tall and ready to burn and these fires move incredibly quickly.”
Tomorrow should be hot again, heading for 34 degrees in the city.
Total fire bans will be in place tomorrow for the Greater Hunter and Central Ranges areas.
