The WMO have released an update on the El Niño situation, reporting that despite warming of the Tropical Pacific Ocean until June, so far the overlaying atmosphere has failed to respond. The ocean temperature anomalies have decreased over the past two months with most atmospheric indicators (e.g., sea level pressure, cloudiness and trade winds) remaining near neutral levels, indicating that El Niño conditions have not yet become established.
