This report presents the key findings and recommendations for strengthening multi-hazard early warning systems in the Caribbean, following the first-ever systematic review of their performance in a post-disaster environment. The review took place after the passage of Hurricanes Harvey, Irma and Maria which significantly impacted more than 12 island States in the region in 2017.

Key findings include:

• The availability of storm-surge forecasts providing probable storm surge height, as well as flash flood early warning systems, with related products for operational use, would contribute to reducing loss of life and assets across the region. Storm-surge forecasting pilots in the Dominican Republic and Haiti show promising results.
• There is limited understanding of how to include gender in early warning systems. In particular, there is a need for increased integration of gender bureaus in preparedness and early warning system initiatives. The review revealed a need for a systematic analysis of how different genders access, communicate and use warnings and alerts. This should be a central component of all early warning system initiatives.
• The respective roles of National Meteorological and Hydrological Services and National Disaster Offices need to be better identified in relation to standardized operational procedures to ensure functioning early warning systems and a continuous flow of information during and after events.
