El Nino likely to return this year: WMO

El Nino weather conditions associated with droughts and flooding have a 50-60 percent probability of returning this year, the UN World Meteorological Organization (WMO) said yesterday. The last El Nino was in 2015-2016. The phenomenon has been linked to exacerbating droughts in the Horn of Africa, coral bleaching the spread of the mosquito-borne Zika virus in South America two years ago.
