Increasing signs La Nina could form during spring

There are increasing signs La Nina could form during spring. Sky News Meteorologist Rob Sharpe explains how it affects Australia’s weather. “When La Nina arrives, it means more rain could be on the way,” he said. “La Nina has a minimal impact, however, on the west and the far south of the country but for the rest of Australia, as La Nina arrives, there’s a higher chance of rain and flooding.”
