Sydney, Brisbane, Melbourne weather: ‘Catastrophic’ fire alert for one Aussie state as storms batter the southeast

A hot air mass has sparked a ‘catastrophic’ fire alert in one Aussie state as showers and storms batter large swathes of the southeast.

Victoria and South Australia will experience warm and windy conditions on Saturday with temperatures to reach the mid 30s.

A catastrophic fire danger warning has been forecast for the Eastern Eyre Peninsula and Yorke Peninsula regions in South Australia.

Temperatures in northern parts of the state will skyrocket to 40C including Moomba, Coober Pedy and Marree.

Severe fire danger ratings have been declared in ten regions across South Australia, with firefighters warning the conditions are some of the deadliest this year.

The fire danger warning has been elevated as strong wind gusts are set to combine with the warm weather system.

An extreme fire danger has also been forecast across parts of Victoria’s northwest, including the regions of Mallee and Wimmera.

Emergency services have issued a Watch and Act alert for residents in Gellibrand and Kawarren in Victoria’s south.

‘There is a bushfire at Railway Line Road, Kawarren that is not yet under control. The bushfire is travelling from Railway Line Road in a southerly direction towards Frys Road,’ the warning states.

An emergency warning has also been issued for residents in Dereel between Geggies Road and Gumley Road.

A total fire ban is in place for Mallee and Wimmera amid the warm weather.

The warm conditions are being driven by a cold front in the waters off South Australia and a low pressure trough that has been pushed from Western Australia towards the south.

Meanwhile, the Bureau of Meteorology has forecast showers for parts of the east coast of Queensland and NSW.

‘Inland parts of Queensland could see significant thunderstorms and maybe some severe thunderstorms including parts of the Maranoa and Warrego,’ Senior Meteorologist Angus Hines explained.

‘A few storms are possible around the western slopes and plains in the far inland of New South Wales … [and they] may bring some strong wind gusts.’

Queensland’s southeast was issued a severe storm alert from Friday with the Bureau warning of potential flash-flooding and heatwave conditions.

NSW and Victoria are set to bear the brunt of the storms on Sunday and Monday as a cold front moves south.

Large parts of Western Australia will also receive thunderstorms, with the state’s inland regions to receive the brunt of the wet and wild conditions.
