For the third year in a row, Southern Californians should expect yet another La Niña winter. With a 91% chance that it will arrive, another La Niña event can bring another year of drought.

During normal weather trade winds, which blow east to west, push warm surface waters towards the Eastern Pacific and Asia. In La Niña events stronger than average trade winds continue to push warm waters east, but also bring colder water to the surface.

Typically, during a La Niña event, the weather will be drier and warmer in Southern California, while wetter and colder in areas like Northern California and Oregon.
