70 percent chance of La Niña forming, says weather agency
And rare thundersnow in Australia
The weather agency Weatherzone updated its El Niño–Southern Oscillation (ENSO) outlook saying there is a 70 per cent chance of La Niña forming before the end of 2020.
La Niña brings colder waters and causes sharp shifts in on-land weather conditions.
The last significant stretch of La Niña in Australia occurred between December 2010 and March 2011 and resulted in the country’s wettest two-year period on record.
Meanwhile, Antarctic air will continue to spread over south eastern Australia between now and Sunday, causing a wintry mix of wind, rain, hail and snow in multiple states,” Weatherzone meteorologist Ben Domensino said. “A few places may even witness rare thundersnow (lightning and snow at the same time).”
Hobart, Melbourne, Canberra, Sydney and Adelaide are all forecast to see drops in minimum temperatures into the single figures beginning tomorrow.
