Great, Experts Reckon The Rain On Australia’s East Coast Could Last For Months

Bad news, lads: there’s a chance that the shit rainy weather won’t properly clear up till August. At least all this rain means you have an excuse to invest in a really cute pair of gumboots.

With serious floods wreaking havoc across the country and deluges of rain plundering Australia’s East Coast, we’re all wondering when exactly we can expect a dry day.

Please, I just need to wash my sheets. According to experts though, there’s a chance that the wet weather could plague us until well into winter.

Why will the wet weather last so long?

It turns out that Ms La Niña, my worst nemesis, is predicted to end in May. But after May is winter (famously), when much of the East Coast usually experiences its wettest weather.

So basically, our soggy spring and summer could be followed by an equally wicked winter.

Dr Nandini Ramesh from the University of Sydney told the ABC that it could be a while before Sydney folk are basking in the sun.

“Forecasts for the La Niña event say that it’s going to persist until May,” she said.

“But then the wintertime is when we get most of our rain.”

Plus, we can’t really confidently predict when exactly La Niña will abandon our shores. Weather, she’s a fickle beast.

What about the hot, sweaty temperatures?

According to the Bureau of Meteorology (BOM)’s climate outlook, both rainfall and temperatures are predicted to be higher than the median until at least May.

Cool! Good! Love! I’m terrified of climate change!

“March to May rainfall is likely to be above median for parts of central and eastern Australia,” the BOM said.

“March to May maximum temperatures are likely to be above median for most of Australia. Only a small area of the central NSW coastline is likely to have below median temperatures.”

It also reported that the minimum temps for March to May will probably be warmer than the median across Australia.

While the south-east of Queensland is dealing with horrific floods, north and central Queensland is currently undergoing a serious heatwave.

Laura Boekel, one of BOM’s senior forecasters, told the ABC that temperatures in the regions were firmly above average.

“Innisfail and Cairns is looking to be 36 degrees Celsius today, where their March average is 30.5C. So pretty significantly above average,” she said.

I’ll say it again: cool, cool, cool, cool.

As put by the BOM in their climate forecast, both the temp and the rain is influenced by global warming.

“Australia’s climate has warmed by around 1.47°C for the 1910–2020 period. Rainfall across northern Australia during its wet season (October–April) has increased since the late 1990s,” it said.

“In recent decades there has been a trend towards a greater proportion of rainfall from high intensity short duration rainfall events, especially across northern Australia.”

What about those one-in-a-1000-year floods?

Severe flooding has devastated south-east Queensland and northern NSW in the last week.

According to the BOM, it’s really hard to predict weather events for into the future. But a spokesperson told the ABC that more major floods were “definitely” a possibility.

“Extreme weather events that we see really only start to show a signal on computer models at around about day seven,” they explained.

This might be confusing if you’ve seen chatter about the floods in NSW being “one-in-1000-year” events.

NSW Premier Dominic Perrottet used the phrase when describing the flooding up in Lismore. The claim comes from a 2014 Lismore City Council Floodplain Risk Management Plan, as per 7News.

That phrase has an actual scientific meaning behind it — and it doesn’t necessarily mean that we won’t see another flood for another 1000 years. Basically, it means that there’s a 0.1 per cent chance of a similar flood happening.

Obviously, though, that’s not how the phrase is read by most people.

Dr Tom Mortlock from Macquarie University told The Guardian why it was misleading.

“It implies we would be waiting another 1,000 years before we see another flood of this magnitude again,” he said, pointing out that Sydney saw a similar flood last March. So really, there’s no excuse for the government not to plan for weather events like this.

What causes weather patterns like this?

While obviously La Niña has prompted a number of these specific weather events, climate change also plays an important role.

The Climate Council explained that global warming has made the earth’s atmosphere “warmer, wetter and more energetic”.

A warmer atmosphere holds more moisture, which can lead to more rainfall in short, intense bursts — the kind of rain which increases the risk of flash flooding.

Plus, that extra heat also means extra energy for the “weather systems that generate intense rainfall”.

At the end of the day, one of the best ways of preventing more intense flooding and rainfall like the East Coast is currently experiencing is to actively fight climate change. Now someone let our politicians know, please.
