Australian firefighters trying to contain bushfires have warned people to take action now because they "may not get help" on Tuesday.
The New South Wales Rural Fire Service (NSW RFS) said on Sunday that they were expecting severe and extreme fire dangers across broad parts of the country's most populous state, including near the nation's largest city, Sydney.
The NSW RFS wrote on Twitter: "Tuesday 12 November will be a dangerous day. Widespread areas of severe and extreme fire danger.
"With so many fires already burning, homes and lives will be at risk. If you are threatened by fire, you may not get help. Start taking action now."
Bushfires in New South Wales have killed three people and at least 150 homes have been destroyed since Friday, when a record number of emergency-level fires were declared in the state.
More than 30 people are injured and about 350 koalas have been killed in the town of Port Macquarie in New South Wales.
The daughter-in-law of Vivian Chaplain, who was one those who died, spoke to the 69-year-old on the phone before her death.

Chrystal Harwood said: "I was the last one to speak to her. She was in absolute panic. She said, 'We're on fire. There's fire everywhere. I need the boys here now.'
"Before I even got to tell her to just get out, she'd hung up on me. I couldn't get back through to her. I tried so many times."
The road to Mrs Chaplain's house was described as a "tunnel of fire" in an appeal for help on social media.
She died in hospital after being found unconscious with serious burns.
Rural fire service commissioner Shane Fitzsimmons said the most intense fires have been seen in the northeast of New South Wales, where flames have been fanned by strong winds.
He added that firefighters found a body in a burned car near Glen Innes on Saturday.
Five others who were missing have reportedly been accounted for.
More than 70 fires were burning in New South Wales on Sunday morning and, while none were at emergency level, 36 were not under control.
More than 50 fires were burning further north in Queensland on Sunday morning – and the lightning of any outdoor fires and certain activities that could cause fires have been banned in 42 local areas across the state.
Queensland Fire and Emergency Services acting commissioner Mike Wassing said in a statement: "We're experiencing tinder box-like conditions across much of the state and all it takes is one spark to start a fire that may burn for days."
Almost 5,000 homes have been evacuated in Queensland over the last 48 hours with many residents unable to return, according to the Australian Broadcasting Corporation.
The annual Australian fire season which peaks during the Southern Hemisphere summer has started early after an unusually warm and dry winter.
Mr Fitzsimmons said little reprieve in fire conditions could be expected over the next week or throughout the summer months of December, January and February.
He continued: "The forecast for the balance of the season continues to be driven by above-normal temperatures (and) below-average rainfall to dominate over the coming months."
