La Nina fading, expected to end soon
Sea surface temperatures in the eastern tropical Pacific Ocean swing back and forth every few years (sometimes more) like an irregular pendulum. The warm phase is known as El Niño; the cool phase—which it has been in for the past two winters—is called La Niña.
According to NOAA’s April 2012 ENSO Diagnostics Discussion, La Niña is fading and will likely be over by the end of April.
