Double dip La Nina

Double dip La Nina forecast for Pacific summer

La NiƱa is the phenomenon where the trade winds become stronger, warming waters in the Western Pacific and causing the sea surface temperatures in the Central and Eastern Pacific to cool.

These conditions can mean cooler and above normal rainfall in the west compared to the eastern Pacific.

Climate models and prediction tools used by Pacific National Meteorological and Hydrological services (NMHSs) show this phenomenon is likely this summer.
