El Nino pattern could emerge by 2018-19 winter

Reuters — The El Nino weather pattern, associated with warmer and wetter weather than usual that may give rise to damaging conditions, could emerge by the 2018-19 Northern Hemisphere winter, with neutral conditions expected to prevail through November this year, a U.S. government weather forecaster said on Thursday.
