A strong El Niño event during 2019 appears unlikely, according to a new World Meteorological Organization Update, which is based on forecast models and expert opinion from around the globe. Sea surface temperatures in the tropical Pacific Ocean have been at borderline to weak El Niño levels in April and early May 2019. Some El Niño-like atmospheric patterns have also been present.

There is a 50-60% chance of El Niño developing by May 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures in the tropical Pacific were at or slightly below El Niño thresholds in January and early February 2019. Some El Niño-like atmospheric patterns also emerged around late January.

There is a 75-80% chance of an El Niño developing by February 2019, although it is not expected to be a strong event, according to the latest update from the World Meteorological Organization (WMO). Sea surface temperatures are already at weak El Niño levels in part of the tropical Pacific, although the corresponding atmospheric patterns have not yet materialized.

The powerful 2015-2016 El Niño has passed its peak but remains strong and will continue to influence the global climate, according to the latest update from the World Meteorological Organization. It is expected to weaken in the coming months and fade away during the second quarter of 2016. Eastern and central tropical Pacific Ocean surface temperatures were more than 2 degrees Celsius above average in late 2015, providing evidence that the 2015-16 El Niño is one of the strongest on record, comparable with the 1997-98 and 1982-83 events. It is too early to establish conclusively whether it was...

Geneva, 17 May 2017 – The annual meeting of the World Meteorological Organization (WMO) Executive Council concludes here today after adopting decisions aimed at enhancing weather, climate and hydrology services around the world. A particularly important issue, the need to strengthen aeronautical meteorological services, was addressed through a one-day special dialogue with representatives from the aviation sector. Aviation is one of the most weather-sensitive of all economic sectors. It is also changing rapidly. With air traffic doubling every 15 years, competition increasing and air safety...

African leaders are coming together this week for action on modernizing weather and climate services, which inextricably link the Continent’s development, climate, and resilience agendas. Weather and climate drive nine out of ten disasters in Africa, threatening Africa’s hard-won development gains. Floods, droughts, tropical cyclones, and landslides continue to cause heavy damage and losses to livelihoods. Over the last two decades, these disasters have cost the continent US$10 billion dollars. Given the increasing climate variability, these disasters are projected to increase in frequency...
