Nowcasting Guidelines – A Summary
Forecast
Bulletin nº Vol 68 (2) - 2019
27
Publish Date: 27 November 2019
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.

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).

In order to accurately predict the day-to-day evolution of weather systems, one needs a detailed description of the initial state of the atmosphere. A good picture of the actual atmospheric conditions is therefore required. Predictability of the atmosphere associated with its initial state is, however, limited to approximately 10 days.

High-impact weather has always posed challenges for crisis management and risk prevention. Nowcasting provides very short range weather forecasts (0–6 hours) and warnings in a timely manner and in high spatial detail. It can help end users such as civil protection authorities, hydrologists and road safety services in their time-critical applications to respond, prepare and take actions for high-impact weather.
