El Niño/La Niña Update (September 2011) Publication 01 septembre 2011 Adobe Stock / Microgen Neutral conditions have prevailed over the tropical Pacific, following the dissipation of the 2010-11 La Niña event by early May 2011. However, a few weak remnants of La Niña have persisted, particularly in some atmospheric features, and in recent weeks the surface as well as sub-surface waters in the eastern and central tropical Pacific Ocean have also cooled. Model forecasts and expert interpretation suggest persistence of near-neutral conditions or the re-emergence of La Niña conditions.
