The WMO says there is a 50-60% chance of El Nino returning after June 2017, though forecasts made before June are less certain. IRI's chief forecaster reports that many climate models have predicted an El Nino after the current neutral period.
A rising probability of El Nino raises the risk of drought in Australia, Southeast Asia and southern Africa, which could tighten grain and oilseed supplies later in the year. The price impact depends on whether the forecast firms up.
