US - 13 July 2017: A U.S. government weather forecaster on Thursday said there are no active El Niño or La Niña patterns and that neutral conditions are likely in the Northern Hemisphere into winter 2017-18.
However, chances for El Niño remain elevated, between 35 and 45 percent, relative to the long-term average, the National Weather Service's Climate Prediction Center said in a monthly forecast.
