A shift towards a La Nina weather pattern is anticipated, potentially elevating the risk of Atlantic storms during hurricane season. The US Climate Prediction Center has raised the likelihood of La Nina formation to 53% for September, October, and November. This marks an increase from 47% the previous month. Forecasters expect a weak La Nina to develop in the Northern Hemisphere's fall and winter, characterized by sea surface temperatures dropping at least 0.5C below normal. This pattern can lead to drought in Southern California and certain agricultural areas while causing heavier rainfall in Indonesia and northern Australia.
