Sea surface temperatures of the central and eastern equatorial Pacific have been cooler than normal since last October, albeit with a gradual warming trend in the past two months. Climate models around the world generally forecast the central and eastern equatorial Pacific to continue to warm in the next few months. Hence, even if the criteria for defining a La Niña event are reached by the end of March, the anomaly is expected to be short-lived and weak.
