El Niño/La Niña Update (November 2011) Publication 17 November 2011 Adobe Stock / Microgen La Niña conditions were re‐established in the tropical Pacific during August, after a brief period of neutral conditions following the significant La Nina of 2010‐11. Model forecasts and expert interpretation suggest that La Niña should remain in place until at least the end of 2011, with some further strengthening possible. The current La Niña is likely to be considerably weaker than the La Niña event of 2010‐11.
