WMO Guidelines on Multi-hazard Impact-based Forecast and Warning Services - Part II: Putting Multi-hazard IBFWS into Practice

The guidance provides practical information and case studies on how to move from weather forecasts and warnings issued by National Meteorological and Hydrological Services to the provision of impact-based forecast and warning services of multiple cascading hazards (for instance a tropical cyclone, which triggers flooding, storm surge, wind damage, impacts on infrastructure, transport and energy and on health systems).

The new edition benefits from significant research into exposure and vulnerability and incorporates extensive input from both service providers and the user community. It underlines the paramount importance of partnerships and dialogue between scientists, forecasters, disaster managers, community leaders and decision-makers.
