The WMO's May 2019 El Niño/La Niña update says Pacific sea surface temperatures have been at borderline to weak El Niño levels since October 2018. The atmosphere began showing El Niño-like patterns only in February.
The chance of El Niño in June-August is 60-65%, and a strong event in 2019 appears low.
The update confirms that a strong El Niño is unlikely, which reduces the chance of major drought in key producing regions. This keeps weather risk premium modest for feed grains and oilseeds.
