El Niño/La Niña Update (July 2010)

Following the rapid dissipation of the 2009/10 El Niño in early May 2010, a brief 

period of neutral conditions prevailed, leading to the current state of borderline 

La Niña conditions. These borderline conditions are more likely than not to 

strengthen to become a basin-wide La Niña episode during the second half of 

2010. It is also possible, but less likely, for neutral conditions to prevail during 

the remainder of 2010.
