The year 2019 concludes a decade of exceptional global heat, retreating ice and record sea levels driven by greenhouse gases from human activities. Average temperatures for the five-year (2015-2019) and ten-year (2010-2019) periods are almost certain to be the highest on record. 2019 is on course to be the second or third warmest year on record, according to the World Meteorological Organization.

Coastal inundation occurs along vulnerable coastlines. The combination of storm surges – typically from tropical cyclones or extratropical storms – and waves, with riverine flooding at various tidal states regularly leads to major loss of life. At least 2.6 million people are estimated to have drowned due to coastal inundation caused by storm surges over the last 200 years (Dilley et al., 2005).

An international expert task team on nowcasting has developed the WMO Guidelines for Nowcasting Techniques (WMO, 2017) to initiate a process for an enhanced integrated and seamless WMO Data-processing and Forecasting System (DPFS). Their purpose is to help National Meteorological and Hydrological Services (NMHSs) by providing them with information and knowledge on how to implement a nowcasting system with the resources available to them and an understanding of the current state of science and technology.

An operational system has been developed and implemented for the Fiji Islands to produce and disseminate new early warning information on coastal flooding, which will help save lives and protect property in low-lying, populated coastal areas. There is potential to enhance this early warning platform in the future and to extend it to other South Pacific island nations, and even consider extension to include other coastal flooding sources such as tsunamis.

The World Meteorological Organization has been awarded the 2018 LUI Che Woo Prize for Welfare Betterment. The citation recognizes that the persistent effort of WMO has been “pivotal in the tenfold reduction in global loss of life from extreme weather, climate and water-related events observed over the past half-century.”

It has been described as the most important report ever published in the 30-year history of the Intergovernmental Panel on Climate Change (IPCC) and an “ear-splitting wake-up call to the world.” The new report on Global Warming of 1.5 °C made headline news around the world with its stark message that limiting warming to 1.5 °C would require unprecedented transitions in all aspects of society.

Weather is a key factor determining the success of the Winter Games. The next Winter Olympic Games will take place from 4 to 20 February 2022, in the municipality of Beijing and the neighbouring Hebei province, in China. The Paralympic Games will follow a month later, from 4 to 13 March. The scheduling of the outdoor events for the Games will rely on very short-term forecasting and nowcasting.
