The NSW State Emergency Service warned there will be a heightened risk of flooding in the state in coming alerts after the BoM issued its La Nina alert. "Historically, when La Nina alert criteria have been met, La Nina has subsequently developed around 70 per cent of the time; this is approximately triple the normal likelihood," the Bureau said in a release.

This means there is a 70 per cent chance of La Niña returning this spring. La Niña refers to changes in sea surface temperatures in the tropical Pacific Ocean, with waters in the eastern Pacific being cooler than normal, and waters in the western tropical Pacific being warmer than normal.

“Should a La Niña event be established in the Pacific Ocean, the wet conditions will persist into summer.” BOM declared that the latest La Niña ended in June. In November, when La Niña became “established”, BOM predicted it would be “short-lived” and would end in late summer or early autumn. The Bureau of Meteorology (BOM) has moved from “La Niña Watch” to a “La Niña Alert”. The likelihood of La Niña returning this spring is three times the normal risk, meaning there is a high chance of above average rainfall for most of the eastern two-thirds of Australia and increased risk of flooding. Most of Australia is in for a wet spring and summer with a map showing what parts of the country have a greater chance of extra rain.
