La Nina 2021 weather event proclaimed for Australia’s summer

Australians are bracing themselves for a wet and windy summer for the second consecutive year as a la Niña weather event forms in the Pacific, meteorologists said on Tuesday.

‘The current model outlooks suggest this La Niña will persist until the late southern hemisphere summer or early autumn 2022,’, the bureau said, extending the longevity of the event from previous forecasts saying it would start unravelling in late January.

Earlier this month the BoM issued a warning for an La Nina event this summer, meaning that there is a 70 percent likelihood La Nina will form in the months ahead and produce cool, wet weather.

Andrew Watkins, the bureau’s head of operational climate services, said La Niña would also heighten the chances of cooler than mean day temperatures for much of Australia.

With the city’s main Warragamba Dam already 99.2 per cent full, some weather experts are increasingly worried about increased flood danger this summer.
