La Niña appears to be arriving sooner than expected. Reuter’s weather expert Karen Braun says the cold phase of tropical Pacific Ocean surface temperatures is occurring more rapidly than originally thought. New data indicates that the development of La Niña is underway.
Organizers of a government forecast model announced the model had accumulated an error that was skewing results for global sea surface temperatures. Correction of the error has led to the prediction that La Niña will fully develop by July, compared to the previous forecast that was calling for El Niño to continue through the summer.
