Two firefighters - a man and a woman believed to be aged in their 40s - have been treated by paramedics on a Hunter fireground.
Ambulance NSW confirmed just before 5pm on Tuesday that paramedics had treated two firefighters after they collapsed.
A fire burning at North Rothbury, which had threatened properties earlier on Tuesday, has been downgraded from an emergency warning to Watch and Act.
It is understood three properties have been damaged as a result of the fire, but the extend of the damage is unclear.
Wine Country Drive was closed and residents evacuated when the blaze was at its height.
The NSW Rural Fire Service declared dangerous fire conditions for Tuesday, November 12, and Premier Gladys Berejiklian has announced a State of Emergency.
Firefighters will enforce a total fire ban across the state on Monday and Tuesday, warning the Hunter is expected to experience the highest possible level of fire danger on Tuesday, when maximum temperatures are forecast to hit 38 degrees and wind speeds up to 40 kilometres per hour.
A statement from the NSW Rural Fire Service said "catastrophic" fire danger is forecast on Tuesday in the Hunter and Greater Sydney, with high temperatures, strong winds and low humidity all contributing to worsening weather conditions.
We will share updated information here throughout the day as it unfolds.
