The Nigeria Hydrological Services Agency (NiHSA) has issued a warning about potential flooding in 107 local government areas across 29 states and the Federal Capital Territory between September 1 and 15.
According to the News Agency of Nigeria (NAN), the advisory—released on Monday in Abuja—is based on forecasts from the 2025 Annual Flood Outlook (AFO), supported by real-time hydrometric data, river level predictions, and satellite imagery.
The alert, signed by the agency’s Director-General, Mr. Umar Mohammed, indicates that over 631 communities and more than 50 critical transport and infrastructure sites are at risk.
NiHSA noted that the flood risk ranges from moderate to severe, with possible incidents of river overflows, flash floods, and localized flooding in low-lying and riverine regions.
The states under watch include Adamawa, Akwa Ibom, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, and Ebonyi.
Others are Edo, Gombe, Imo, Jigawa, Kaduna, Kebbi, Kogi, Kwara, Lagos, Nasarawa, Niger, Ogun, Ondo, Plateau, Rivers, Sokoto, Taraba, Yobe, and Zamfara.
NiHSA said the floods could disrupt highways and bridges, threaten lives, livelihoods, agriculture and public infrastructure, and heighten risks of water contamination and disease outbreaks.
It urged federal and state emergency agencies to activate contingency plans, deploy response teams and pre-position relief materials.
Local governments and community leaders were advised to intensify sensitisation campaigns, identify evacuation routes, and prepare shelters for vulnerable residents.
“Communities and individuals should avoid flooded roads, move to higher ground where necessary, and follow official safety instructions.
“This alert is to safeguard lives and property, and we call for proactive measures across all levels,” Mohammed said.
NiHSA assured that it would continue to monitor the hydrological situation and provide timely updates through its official platforms.
