IRI's December climate briefing says El Niño-like ocean conditions in the equatorial Pacific have persisted since late September 2018, with the Niño3.4 anomaly at 1.0°C, but the atmosphere has not fully joined in. The atmosphere has become less El Niño-like over the past month, leaving the outlook uncertain.
Uncertainty over whether El Niño will fully develop keeps weather risk premium in grain and oilseed markets, since a strong event could cut output in Southeast Asia and Australia.
