The Federal Government has issued a fresh warning that 29 states and the Federal Capital Territory, along with 107 local government areas and no fewer than 631 communities, face high risk of flooding in the coming weeks.
The Nigeria Hydrological Services Agency (NIHSA), in its latest alert, said the threat is expected to persist until mid-September, with possible severe impacts on lives, livelihoods, and infrastructure.
The Director-General of the agency, Arc. Umar Mohammed, explained that the warning is backed by real-time hydrological data, river-stage forecasts, and satellite mapping under the 2025 Annual Flood Outlook.
States identified include Adamawa, Akwa Ibom, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, Gombe, Imo, Jigawa, Kaduna, Kebbi, Kogi, Kwara, Lagos, Nasarawa, Niger, Ogun, Ondo, Plateau, Rivers, Sokoto, Taraba, Yobe, Zamfara and the FCT.
According to the agency, more than 50 critical transport and infrastructure facilities could be disrupted, while risk levels range from moderate to very high.
Communities in riverine and low-lying areas are particularly vulnerable to river over-banking, flash flooding, and localised inundation.
Expected impacts include damage to roads and bridges, threats to farmlands and property, contamination of water sources, and increased public health concerns in affected locations.
NIHSA has urged federal and state ministries, disaster management agencies, and local councils to activate contingency plans, deploy response teams, and pre-position relief materials.
Community leaders are advised to step up sensitisation campaigns, identify safe evacuation routes, and prepare shelters for displaced persons.
Residents in high-risk areas have also been cautioned to move to higher ground, avoid flooded roads, and obey official safety directives
