Weather: Sydney, Melbourne, Brisbane, Perth, Adelaide Urgent warning over rare weather event

Australians are being warned to brace for another miserable summer with a rare ‘triple-dip’ La Nina predicted to bring heavy rain.

The United Nations’ World Meteorological Organisation (WMO) reported the atmospheric phenomenon would hold until the end of the year – the first time in more than 100 years La Nina has lasted three-consecutive summers.

The organisation’s El Nino/La Nina report said there was a 70 per cent chance it continued through November, meaning Aussies will be subjected to similar conditions to the start of 2022, which saw torrential rains and mass flooding.

There is a further 55 per cent chance the wild weather will push into February.

The WMO said the prolonged La Nina conditions are a direct result of climate change caused by humans.

‘It is exceptional to have three consecutive years with a la Nina event,’ Secretary-General Professor Petteri Taalas said in a statement.

‘Its cooling influence is temporarily slowing the rise in global temperatures – but it will not halt or reverse the long-term warming trend.

‘The worsening drought in the Horn of Africa and southern South America bear the hallmarks of La Nina, as does the above average rainfall in South-East Asia and Australasia.’

Australia was lashed with consistent and devastating rainfall last summer that saw large areas of its east coast, particularly in northern New South Wales, destroyed by flooding.

Coastal towns are still reeling from the impact of the wettest summer in 30 years with billions required to repair the destruction.

Meanwhile, parts of Africa and Europe are experiencing the worst droughts in 500 years, with rivers critical for shipping drying up for the first time in centuries.

‘Climate change is undoubtedly more noticeable every year,’ the EU’s Research Commissioner Mariya Gabriel said last month.

‘We are currently noticing a wildfire season sensibly above the average and an important impact on crops production.’

Parts of Africa are suffering from prolonged droughts after four failed wet seasons – with WMO predicting another dry stretch.

‘The new La Nina Update unfortunately confirms regional climate projections that the devastating drought in the Horn of Africa will worsen and affect millions of people,’ WMO’s Mr Taalas said.
