Australia’s Bureau of Meteorology is expected to declare a La Niña event is under way in the Pacific, joining other international agencies to mark a weather pattern that typically elevates flood risks for much of the country.
The bureau’s fortnightly update of Australia’s climate drivers has been at “alert” level for some weeks, implying a 70% chance the thresholds it uses to declare such an event will be crossed later this year.
