El Niño/La Niña Update (October 2010) Document 11 October 2010 Moderate to strong La Niña conditions are now well established in the equatorial Pacific. Sea surface temperature departures in the central and eastern equatorial Pacific are now at, or just above, the mid-range of those found during the past La Niña events. These La Niña conditions are likely to continue at least into the first quarter of 2011. Although the current La Niña has some similarities to past events, its impact upon local climates may differ from those observed in the past. For management of climate-related risks during this event, it is important to consult regional climate information and seasonal outlooks that account for both the prevailing La Niña conditions and other factors with potential influence on the local climate.
