According to Weatherzone, new US-led projections indicated that the La Nina weather pattern that delivered severe rains and devastating severe flooding to Australia's east coast is "starting to break."

This implies that rain will continue to fall on the east coast for the foreseeable future, fueling worries of a "third La Nina" episode.

Sydney has already experienced the rainy start to the year, with devastating floods sweeping in northern New South Wales and southeast Queensland.

A catastrophic mix of meteorological phenomena not seen in over 50 years could see more communities in Australia submerged in increasing flood levels throughout the rest of 2022.

As per Sky News chief meteorology scientist Tom Saunders, evidence have emerged showing that the present La Nina extreme rainfall system impacting Australia may be reinforced by another storm, potentially bringing severe flooding and rainfall, a negative Indian Ocean Dipole (IOD), as per Australian News.

La Nina has a 59% higher probability of persevering through the cold season in the Southern Hemisphere and a 50% to 55% chance of persisting through the spring in the Southern Hemisphere.

Climate projections from the National Weather Service's Climate Prediction Centre (CPC) in the United States and Columbia University's International Research Institute for Climate and Society were mentioned by Weatherzone.

"It is unusual for La Nina's imprint to be so well entrenched in both the water and the atmosphere at this time of year. In the next weeks and months, keep a watch on the persistent strength of this current La Nina," as per Weatherzone.

The BoM verified the formation of the weather event over the Pacific Ocean on November 23.
