The central and eastern equatorial Pacific were persistently warmer than normal (by 0.5°C or more) in the last five months and the sum of sea surface temperature anomalies exceeded 4.0°C. An El Niño event has been established. Based on the latest oceanic observations as well as forecasts by a number of climate models around the world, the El Niño is expected to persist through this spring and summer.
