It’s Looking More More Likely We’re Getting A Third La Niña So Here’s Yr 3 Minute Explainer

In some bad news for your bedsheets/social life/dreams of having a dry house, the Besties of Meteorology — better known as the Bureau of Meteorology — has updated its La Niña status to “alert”. That means it’s looking increasingly likely that we’re going to have a third La Niña. While that’s been on the cards for a little while now, the BoM’s climate models indicate that it’s now “likely” for our spring and summer. “Historically, when La Niña alert criteria have been met, La Niña has subsequently developed around 70 per cent of the time,” the BoM said.
