La Nina: Australia is warned to prepare for one of its wettest summers EVER

Experts have predicted Australia will be forced to endure one of its wettest summers ever – with infamous weather pattern La Nina to blame.

Last summer was the country’s wettest and coldest in several years – and 2021 sounds like it will be no better. 

Dr Andrea Taschetto, an Associate Professor from UNSW Science’s Climate Change Research Centre, predicted a significant downpour before Christmas. 

‘Last summer was particularly unusual in that we did receive lots of rain,’ Dr Taschetto said. 

‘It was the wettest and coolest summer in the past five years and that was basically because of La Nina.’

‘La Nina can sometimes persist for two years so we could see more (repeated) rainfall this summer.’

Her comments come as Australia’s Bureau of Meteorology declared on Tuesday a La Nina event is underway in the Pacific.

The BOM’s Head of Operational Climate Services, Dr Andrew Watkins, said that typically during La Niña events, rainfall becomes focused in the western tropical Pacific, leading to wetter than normal period for eastern, northern and central parts of Australia. 

‘La Niña also increases the chance of cooler than average daytime temperatures for large parts of Australia and can increase the number of tropical cyclones that form,’ Dr Watkins said. 

‘La Niña is also associated with earlier first rains of the northern wet season, as we’ve observed across much of tropical Australia this year.’

The last significant La Nina was back from 2010–12, which saw widespread flooding in some areas.

In some welcome news, BOM experts don’t expect the current La Nina to be as previous years.

Doctor Andrea Taschetto, an Associate Professor from UNSW Science’s Climate Change Research Centre, also believes the downpour will be significant across Australia this summer

Tuesday’s development comes after recent widespread and heavy rainfall saw minor to moderate flooding in many inland rivers across Australia, notably in NSW.  

The Lachlan River, which last week threatened the NSW central west town of Forbes and saw many locals forced to evacuate their homes after urging from the SES, still remains at major flood levels.

Another belt of rainfall is heading towards the east coast, which could see up to 60mm of rain from Queensland into Victoria in the coming days. 

WeatherZone is reporting large parts of the country have experienced between two and four times their normal November rainfall already, with another month’s worth due this week alone.

The Mackay region in Queensland will be worst affected, with extreme warnings to be in place from Wednesday to Friday.

The ACT will also be swallowed by storms, with eastern parts of South Australia to experience significant rain.

Perth is the only Australian capital city where the rain is tipped to miss. In Sydney, umbrellas are tipped to be in vogue until at least November 28 – before the summer downpour.

Major cities will be in the firing line on Friday, with the weather systems set to move closer to the ocean with Sydney, Brisbane, Canberra and Melbourne set to be drenched

BOM climatologist Agata Imielska said there is ‘no sunshine on the forecast in the week ahead for Sydney’ after 15mm of rain on Sunday. 

Thunderstorms are predicted over the next 48 hours, with up to 20mm of rain expected on Thursday.  

With the city’s main water catchment Warragamba Dam already 99.2 per cent full, some weather professionals are also increasingly concerned about heightened flood risks this summer.

‘What this rain is doing is keeping catchments wet across much of the state, Sydney included. Water storages are full, that could see increased flood risk,’ Ms Imielska said.

‘With saturated soils and storages being full, there’s no capacity for rivers and the broader environment to soak up that rainfall. It just means we don’t need as much rain for flooding to occur.’
