El Niño/La Niña Update (June 2009)

Rapid changes in oceanic and atmospheric conditions in the tropical Pacific in 

recent months, and an increasing number of computer model predictions, are now 

pointing to a substantial likelihood of an El Niño event in the second half of 2009. 

However, surface climate conditions in the tropical Pacific are overall still 

considered near-neutral at this time. The situation therefore warrants especially 

careful monitoring over the next couple of months.
