The Nigerian Meteorological Agency, NiMet, has warned that 13 states face a high risk of flash floods between August 11 and 20, 2026
NiMet issued the warning in an advisory posted on its X handle on Tuesday, listing Sokoto, Zamfara, Kebbi, Niger, Kaduna, Nasarawa, Adamawa, Plateau, Benue, Kogi, Taraba, Cross River and Akwa Ibom as states at high risk.
The agency said the outlook was based on forecast rainfall intensity, soil moisture, drainage capacity, terrain and dam characteristics.
It said the advisory was intended to support early preparedness, emergency response and disaster risk reduction.
NiMet warned that flash floods could occur in flood-prone, low-lying, urban and riverside communities, with possible impacts including road closures, traffic congestion and transport disruptions.
It also warned that flooding could temporarily disrupt electricity and telecommunications services, while heavy rainfall could reduce visibility and affect road and aviation operations.
The agency also warned that waterlogging could damage farmlands, crops and livestock, while flash floods could destroy roads, bridges, drainage and other critical infrastructure. It further cautioned that stagnant floodwaters could increase the risk of waterborne diseases.
NiMet urged residents to monitor weather forecasts and flood alerts, avoid walking or driving through flooded roads and fast-flowing water, and be ready to relocate from vulnerable areas.
It also called on emergency authorities to strengthen surveillance and pre-position response teams, and advised farmers to improve drainage and move livestock, machinery and produce away from flood-prone areas.
