The Nigeria Hydrological Services Agency (NiHSA) has issued a 15-day flood alert for 198 local government areas across 30 states and the Federal Capital Territory (FCT), warning residents to brace for potential flooding between August 7 and 21, 2025.
According to the agency, 832 communities are at varying risk levels categorised as very high, high, or moderate based on rainfall intensity and local topography.
The very high-risk states include Adamawa, Bauchi, Bayelsa, Benue, Borno, Delta, Gombe, Kebbi, Kogi, Lagos, Niger, Ogun, Rivers, Yobe, and Zamfara. High to moderate-risk states are Akwa Ibom, Anambra, Cross River, Ebonyi, Edo, the FCT, Imo, Jigawa, Kaduna, Kwara, Nasarawa, Ondo, Plateau, Sokoto, and Taraba.
NiHSA also warned of potential disruptions to over 100 major transportation routes in flood-prone areas.
“Residents in vulnerable areas must remain vigilant, follow early warning directives, and work closely with emergency response agencies,” NiHSA stated. The agency urged communities to prepare evacuation plans and closely monitor its weekly state-level forecasts for updates.
NiHSA Director General, Umar Mohammed, stressed the need for proactive measures from state governments, local authorities, and the public, saying the alert aligns with the agency’s mandate to safeguard lives and property.
