El Niño/La Niña Update (August 2009)

El Niño conditions have become established over the tropical Pacific, and it is very 

likely that these will continue at least through the remainder of 2009 and probably 

into the first quarter of 2010. The ocean surface and subsurface in the central and 

eastern Equatorial Pacific has been substantially warmer than normal during June 

and July, supporting the development of an El Niño event.
