WORSENING conditions on Tuesday have forced the NSW Rural Fire Service (NSW RFS) to upgrade the Kerry Ridge bushfire to "Watch and Act".
The out of control blaze, which is burning in the Wollemi National Park, Putty State Forest, Coricudgy State Forest and Nullo Mountain State Forest, encompasses the Muswellbrook, Singleton and Mid-Western LGAs.
It's now more than 128,000 hectares in size.
"The fire is most active in the area of isolated properties along Growee Road, Nullo Moumtain and Coxs Crown Road," a NSW RFS spokesperson said.
"It's also moving north towards properties in the Widden, Baerami Creek and Martindale area.
"The fire is moving east towards properties in Milbrodale, too.
"Firefighters, supported by heavy plant machinery and water-bombing aircraft, continue to work on strengthening containment lines.
"Putty Road is closed, to undertake back-burning operations, between Milbrodale Road and Colo Heights Road.
"The fire has merged with the Oaky Creek and Paddock Run bushfires.
"Deteriorating conditions are forecast on New Year's Eve (December 31) with expected high temperatures and strong winds."
