Overview of the High Impact Weather Project and its Achievements

This talk will provide an overview of the HIWeather project which ran from 2015 to 2024. Its early work responded to needs identified in the Sendai Framework while its outputs have contributed to the planning and delivery of the UN Secretary General's Early Warnings for All initiative. Along with other initiatives, both in the USA and worldwide, it has contributed to a radical re-imagining of warning systems for weather-related and other hazards, in which the way a warning will be used is both the starting point and the ending point. It has delivered pioneering research into impact-based warnings within the context of an end-to-end view of the warning production chain, which emphasises partnership and connectivity among disciplines and organisations.
