This map shows our early-stage impact model, highlighting how Hurricane Melissa has affected communities throughout Jamaica. We are continuously updating and refining this model as more data becomes available. Hurricane Melissa originated in the central Caribbean Sea and made landfall in Jamaica on October 28, 2025 as a Category 5 system. It brought sustained winds of up to 185 mph (298 kph), storm surges ranging from 4 to 13 feet (1.2 to 4 metres), and rainfall totals reaching up to 500 mm (20 inches) in several areas. The hurricane caused widespread flooding, landslides, and severe infrastructure damage across multiple parishes. Communities in the southern and eastern parts of the island were among the hardest hit, experiencing major disruptions to transportation, electricity, and communication networks. Since the passage of Hurricane Melissa, the Mona GeoInformatics Institute (MGI), an entity of The University of the West Indies, Mona Campus has been working tirelessly to map, analyze, and share geospatial data that supports disaster response and recovery. Through the use of Geographic Information Systems (GIS), MGI has been able to identify affected areas on a macro level, deduce the level of impact, and this information can guide emergency response teams toward communities most in need. Our GIS-driven models play a crucial role in coordinating aid and relief efforts, ensuring that food, shelter, clothing, and clean water reach those who need them most. MGI’s Executive Director, Mr. Luke Buchanan has outlined that “In the aftermath of Hurricane Melissa, it has become increasingly clear that current relief efforts are not fully leveraging the power of data and geospatial analysis. Too often, critical decisions are being made without access to real-time, location-based information or comprehensive data collection systems. This results in gaps in situational awareness, delayed responses, and challenges in tracking the effectiveness of aid distribution”. Buchanan went on to say “We therefore urge all relevant government agencies and relief partners to integrate geospatial data and mapping technologies more deeply into their operations. Doing so will not only enhance coordination and transparency but also ensure that resources reach the most affected communities more efficiently. MGI stands ready to support these efforts, offering technical expertise, mapping tools, and real-time data solutions to strengthen Jamaica’s resilience and response capacity.” At MGI, we remain committed to leveraging GIS technology to enhance national resilience and improve disaster preparedness. This commitment reflects our mission as part of The University of the West Indies, Mona, to apply research, innovation, and technology in service of our communities.
