Rwanda raises flood preparedness as strong El Niño threatens East Africa

Rwanda is stepping up preparations for potential floods and landslides as regional climate experts warn that a strong El Niño event could bring above-average rainfall to parts of East Africa during the October-December 2026 rainy season.

Government officials and climate specialists are urging authorities to strengthen early-warning systems, protect vulnerable communities and prepare key sectors for the possible consequences of intense rainfall.

The warning was discussed during the 74th Greater Horn of Africa Climate Outlook Forum, held in Kigali on August 17 and 18. The meeting brought together scientists and policymakers to examine regional forecasts prepared by the Intergovernmental Authority on Development’s Climate Prediction and Applications Centre.

El Niño is a naturally occurring climate pattern associated with warmer-than-usual sea surface temperatures in the central and eastern tropical Pacific Ocean. Although the phenomenon develops thousands of kilometres away, it can influence weather patterns across distant regions.

In East Africa, El Niño conditions can contribute to wetter-than-normal seasons in several areas, increasing the risk of flooding, landslides and other weather-related hazards. Rwanda, where mountainous terrain makes some communities particularly vulnerable to landslides, is therefore preparing for potentially difficult conditions.

Rwandan authorities are focusing on improving rainfall monitoring and forecasting, expanding flood early-warning mechanisms, strengthening watershed management and improving disaster-response capacity. Officials are also calling for better protection of critical infrastructure and more effective communication of warnings to communities.

The government has urged institutions and residents to begin preparations before the heaviest rainfall arrives. Measures include clearing drainage systems, protecting vulnerable infrastructure and ensuring that residents understand how to respond when official warnings are issued.

Regional forecasts point to an unusually strong El Niño during the October-December period. Meteorological experts involved in the outlook have estimated a very high probability of El Niño conditions developing during the season, with the possibility that the pattern could persist into 2027.

The forecasts indicate that much of the Greater Horn of Africa could receive rainfall above seasonal averages. Some areas are expected to record more than 300 millimetres of rainfall during the season, while parts of Kenya, Uganda, Burundi, Rwanda and Tanzania could potentially receive more than 400 millimetres.

For Rwanda, the forecasts have increased the urgency of preventive action. Heavy rainfall could place additional pressure on drainage networks, roads, bridges, agricultural areas and communities located in flood- and landslide-prone zones.

Authorities are therefore treating the period before the rainy season as a critical window for strengthening preparedness. Improving warning systems, maintaining drainage infrastructure and ensuring rapid communication with vulnerable populations could help reduce the human and economic impact of extreme weather.

The situation also highlights the growing importance of climate-risk planning across East Africa, where floods, landslides and droughts can have significant consequences for agriculture, infrastructure and local communities.
