Stay tuned for the next update (by September 10th, probably earlier) to see where the MEI will be heading next. La Niña conditions have at least briefly expired in the MEI sense, making ENSO-neutral conditions the safest bet for the next few months. However, a relapse into La Niña conditions is not at all off the table, based on the reasoning I gave in September 2010 – big La Niña events have a strong tendency to re-emerge after ‘taking time off’ during northern hemispheric summer, as last seen in 2008.
