The National Weather Service on Thursday issued an El Niño watch for next fall and winter, raising the prospects for cooler, wetter weather across most of the United States and a significantly milder late hurricane season, according to NBC News.
The service’s Climate Prediction Center believes there is a 50 percent chance for an El Niño during the fall and 65 percent chance in the winter. An El Niño begins with warm water in the central and eastern Pacific Ocean and changes weather patterns across the world.
Moving some tropical storm conditions away from the Atlantic Ocean is an effect of an El Niño.

"The forecaster consensus favors the onset of El Niño during the Northern Hemisphere fall, which would then continue through winter," the climate center said in an advisory. "These forecasts are supported by the ongoing build-up of heat within the tropical Pacific Ocean."
