While forecasters are still assessing the degree of the EL Niño phenomenon, they all appear to agree that it is currently affecting weather across the globe.
According to the Center, atmospheric and oceanic features reflect an ongoing and strengthening El Niño.
Nearly all models predict El Niño to continue throughout 2015, with many predicting surface sea temperatures (SST) anomalies to increase into the late autumn 2015.
For the autumn and early winter, the consensus of forecasters slightly favours a strong event (temperatures up by an average of 1.5ºC), relative to a weaker event.
A moderate, weak, or even no El Niño remains possible, though at increasingly lesser odds, the Center said.
El Niño will likely be a contributor to a below normal Atlantic hurricane season, and above-normal hurricane seasons in both the central and eastern Pacific hurricane basins, forecasters said.
