Australia moved one step closer to declaring La Nina, issuing an alert for the event as the Pacific Ocean continues to cool.
Sea temperatures in the tropical Pacific are just shy of La Nina thresholds and show a clear progression toward the pattern, the Bureau of Meteorology said on its website on Tuesday. Atmospheric indicators have shown signs of shifting into a La Nina-like state, it said. The bureau issued an alert, meaning an approximately 70 percent chance of the event occurring.
