Many small islands, especially those with the highest risks and the least resources, remain highly challenged in building and sustaining integrated, people-centred, end-to-end early warning systems  that are fully functional across the four interrelated components of EWS. Warning dissemination and communication, and disaster preparedness and response capacities are particular components of EWS requiring strengthening in SIDS . More recent assessments of early warning capabilities in the Caribbean highlight improvements in EWS for weather, water and climate over time . However, progress has been uneven across hazards, governance levels and spatial and temporal scales, with more advanced development of some sub-systems and EWS pillars than others. Significant progress has been made in the area of detection, monitoring, analysis and forecasting of severe weather systems but there is a need to strengthen this area for other climate-related hazards such as wildfires, localised intense rainfall, floods, as well as heatwaves and droughts, which become more important in a changing climate. Assessments also point to specific deficiencies including significant gaps in the area of disaster risk knowledge-particularly the development of risk assessments, the variable capacity for interpreting scientific warning products across states, as well as effective communication of warning messages to populations at risk .
