NiMet warns of flash floods across 13 states in August

The Nigerian Meteorological Agency (NiMet) has issued a stark warning of possible flash floods across 13 northern states, with the high-risk period identified between August 11 and 20, 2026. This advisory serves as a critical early warning system to support proactive preparedness and disaster risk-reduction measures.

The agency's outlook is based on a combination of factors, including forecast rainfall intensity, prevailing soil moisture conditions, the existing drainage capacity, terrain, and dam characteristics. States identified as having a High Flash Flood Risk include Sokoto, Zamfara, Kebbi, Niger, Kaduna, Nasarawa, Adamawa, Plateau, Benue, Kogi, Taraba, Cross River, and Akwa Ibom.

It serves as an early warning and decision-support tool for proactive preparedness, emergency response planning, and disaster risk-reduction measures.

NiMet anticipates that affected areas could experience localized flash flooding, particularly in low-lying, urban, and riverside communities that are prone to such events. The potential impacts are significant, ranging from traffic congestion and road closures to temporary disruptions in electricity and telecommunications services. Heavy rainfall may also reduce visibility, affecting motorists and aviation operations.

Furthermore, the agency warns of potential damage to farmlands, crops, and livestock due to waterlogging. Flash flooding could also compromise critical infrastructure like roads and bridges, while stagnant floodwaters pose an increased risk of waterborne diseases. NiMet strongly advises residents to monitor weather forecasts and flood advisories, avoid driving or walking through flooded areas, and remain alert in vulnerable locations.

Emergency management agencies are urged to enhance surveillance and pre-position response teams. Farmers should improve drainage and secure livestock and produce. Authorities are called upon to prioritize vulnerable communities for monitoring and public sensitization, emphasizing that preparedness is crucial even in areas with lower flood probability, as flash floods can develop rapidly.

Preparedness should be maintained even in areas with lower flood probability, as flash flooding can develop rapidly during intense rainfall.
