What is La Niña?

A La Niña is a phenomenon that produces cooler than average water temperatures in the tropical Pacific Ocean. It is not to be confused with El Niño, which is where warmer water temperatures occur in that part of the world. Both can greatly affect weather around the world.

AccuWeather forecasters use weather phenomena like La Niña or El Niño to make their long-range predictions, which influence weather patterns for months to come.

However, meteorologists say that a La Niña "may not officially develop this winter, but there could be times during the season when the weather patterns act the way they do when La Niña is occurring".

The Climate Prediction Center says that a La Niña usually pushes the jet stream further south during the winter months. As for the Northeast, experts say that precipitation could be more in the form of rain, if it stays warm enough this winter.
