El Niño/La Niña Update (October 2007)

La Niña conditions are now well established across the central and eastern 

Equatorial Pacific. The magnitude of the current sea surface temperature 

departures from normal in the central and eastern Equatorial Pacific are in the 

middle-range of La Niña events found in the historical record. La Niña 

conditions are most likely to continue at least through the first quarter of 2008.
