The Nigeria Hydrological Services Agency has warned of possible flooding in 107 local government areas across 29 states and the FCT between September 1 and September 15.
The News Agency of Nigeria reports that the advisory, issued on Monday in Abuja, is based on projections in the 2025 Annual Flood Outlook.
It is backed by real-time hydrometric readings, river stage forecasts, and satellite mapping.
According to the alert signed by the Director-General, Mr Umar Mohammed, more than 631 communities and over 50 critical transport and infrastructure points are at risk.
The agency said the risk levels ranged from moderate to very high, with threats of river overbanking, flash floods and localised inundation in riverine and low-lying areas.
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.
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.
