NSW firefighters have experienced another difficult day as multiple blazes burned at emergency level across the southeast.
Five emergency warnings were in place on Saturday afternoon for blazes across the NSW south coast and southeast, although by Saturday night all been downgraded.
This included the out-of-control Clear Range blaze which was created from embers that moved kilometres from the ACT's large Orroral Valley fire.
Snowy Monaro Regional Council asked residents in the tiny town of Bredbo to reduce their water usage where possible "to ensure there’s enough water for emergency firefighting efforts".
"Water is currently being used faster than it can replenished," the council posted on Facebook on Saturday evening.
RFS Commissioner Shane Fitzsimmons said there had been no reported damage to homes.
However, structures such as horse stables, sheds and other outbuildings have been lost to fires in the region, he said.
An RFS spokeswoman on Saturday night said there had been unconfirmed reports of up to five structures lost.
The Clear Range fire will continue to be a key focus for the RFS on Sunday, the spokeswoman said.
A southerly wind change is expected to push through and "with any wind change comes added complexities and potential new threats", she added.
"We do urge people in the communities in the entire perimeter of that fire to have a plan in place and to continue to monitor conditions because things are very likely to change with the wind changing over the next 24 hours.
"Keeping in mind tomorrow is still going to be a very hot day with those winds - whilst it's (forecast to be) better than today, it's going to be a key focus for us."
Fire-generated thunderstorms also developed over the Big Jack Mountain, Border Fire and Postmans Trail blazes on the state's south coast.
The pyro-cumulonimbus clouds are "very dangerous for anyone nearby, including firefighters," the RFS posted on Twitter on Saturday afternoon.
Premier Gladys Berejiklian acknowledged in a Twitter post on Saturday that it had been "another difficult day in NSW particularly in the southeast of the state".
Very high fire danger is forecast for Sunday for the north coast, greater Hunter, greater Sydney, Illawarra/Shoalhaven, central ranges, northern slopes and north western fire regions.
Nerriga, which topped 42.4C before 4pm, was among several South Coast locations to exceed 40C on Saturday.
In Sydney, Badgerys Creek, Horsley Park, Penrith and Richmond all hit 46C while Bankstown, Camden and Campbelltown hit 45C.
"Storms, possibly severe, are forecast for many parts of NSW on Sunday including Sydney. Storms inland may raise dust," the NSW Bureau of Meteorology posted on Twitter on Saturday night.
