The IRI's February 2019 ENSO update says tropical Pacific sea surface temperatures cooled to borderline El Niño levels in January and early February, while subsurface waters stayed warmer than average. Atmospheric El Niño patterns developed in late January and February.
The official CPC/IRI outlook carries an El Niño advisory, with a 65% chance of El Niño during Feb-Apr falling to 50% for Apr-Jun.
El Niño raises the risk of drought in parts of Asia, Australia and Southern Africa and of uneven rain in South America, which can tighten supplies of grains and oilseeds. Traders may price in a higher weather premium if the event strengthens.
