Date Time WMO steps up action on La Niña The World Meteorological Organization has strengthened its support to governments, the United Nations, and stakeholders in climate sensitive sectors to mobilize preparations and minimize impacts of La Niña. In October, WMO declared that La Niña has developed and is expected to last into next year, affecting temperatures, precipitation and storm patterns in many parts of the world. Since October, La Niña has continued to strengthen, as equatorial Pacific sea surface temperatures have cooled further. Many National Meteorological and Hydrological Services (NMHSs) have reported that ocean and atmospheric indicators now indicate that the La Niña event has matured and, according to most models, is expected to peak in intensity in either December or January. Thus, Australia’s Bureau of Meteorology says that model outlooks suggest that La Niña is approaching its peak, with a likely return to neutral conditions during the late southern hemisphere summer or early autumn. The latest update issued by NOAA Climate Prediction Center and the International Research Institute for Climate and Society advised of 95% probability of La Niña continuing through to March 2021.
