PASADENA (CBSLA.com) The anticipated blockbuster return of El Niño is looking more like it will be a flop, a climatologist said Monday. Scientists from NASAs Jet Propulsion Laboratory say that unless developing weak-to-modest El Niño conditions strengthen, California will continue to stay bone dry. El Niño describes a weather pattern involving a warming of equatorial waters in the eastern Pacific Ocean, a condition that is associated with increased rainfall on the west coast of North America.
