El Niño/La Niña Update (January 2011) Document 25 June 2011 A significant La Niña episode continues in the tropical Pacific Ocean, with effects extending into adjacent ocean basins. Atmospheric indicators show this episode to be one of the strongest of the last century, while oceanic indicators have been at moderate to strong levels. La Niña conditions are likely to continue through the first quarter of 2011. While many recent regional climate impacts are consistent with the impacts typically associated with La Niña, some differ, and may continue to differ. 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.
