West and Central Africa: 2026 Flooding Outlook (09–13 June 2026)

Forecasts for 9–13 June 2026 indicate a high risk of flooding across several countries in West and Central Africa due to widespread moderate and heavy rainfall. Approximately 8.7 million people could be exposed to flooding, including 5.6 million in areas expected to experience heavy rainfall. Nigeria remains the most affected country, with more than 6.2 million people at risk, followed by Liberia, Cameroon, Côte d’Ivoire, and Ghana. Flood exposure could also affect nearly 430,000 buildings, over 2,600 schools and health facilities combined, 63,000 km of roads, and thousands of hectares of cropland. The outlook underscores the importance of early warning systems, preparedness measures, and coordinated response efforts to reduce the potential humanitarian impact of flooding across the region.
