The Nigeria Hydrological Services Agency (NIHSA) issued a National Flood Advisory (Alert No.: NFA-2026-200), forecasting a medium flood risk across 17 states over the next seven days.
The advisory, effective from July 21 to July 27, 2026, warns of imminent localized inundations along major river channels and floodplains nationwide.
Announcing the advisory in a statement on Tuesday, NIHSA’s Director General and Chief Executive Officer, Umar Ibrahim Mohammed, stressed the urgent need for proactive risk management, timely evacuation, and coordinated action among government agencies to safeguard lives, livelihoods, and infrastructure.
”Our hydrological monitoring network indicates that river stages at critical monitoring stations—including Saminara on the Karam River, Waya Dam Site on the Waya River, and Amber on the Amber River—have exceeded watch and warning thresholds. With 16 gauging stations showing elevated stages, communities along the primary channels face imminent localized flooding. We strongly advise state governments, local authorities, and residents on floodplains to act immediately,” Mohammed said.
The advisory covers 17 States, including Bauchi, Edo, Imo, Kaduna, Plateau, Benue, and 11 additional states, with 16 critical gauging stations across the national hydrometric network flagged at risk.
Exposure assessments show significant of communities and facilities in the flood-prone zones: Bauchi State: 1,841 Communities, 145 Schools, 101 Health Facilities, 8 Markets, Edo State: 148 Communities, 131 Schools, 123 Health Facilities, 4 Markets, 7 Religious Centres, 7 ha of Farmlands, Imo State: 415 Communities, 423 Schools, 198 Health Facilities, 49 Markets, 111 Religious Centres, 75 ha of Farmlands, Kaduna State: 168 Communities, 16 Schools, 3 Health Facilities, 3 Religious Centres, Plateau State: 205 Communities, 137 Schools, 44 Health Facilities, 16 Markets, 81 Religious Centres, 64 ha of Farmlands, and Benue State: 5 Communities, 8 Schools, 2 Health Facilities, 4 Religious Centres.
The Director General called on the Emergency Management Agencies (NEMA/SEMA), local government executives, and community leaders to enforce safety measures without delay:
Immediate Evacuation: Move residents, livestock, and critical household valuables away from floodplains to designated safe shelters immediately, Pre-positioning Relief: Emergency response bodies should pre-position medical, first-aid, water-treatment, and food supplies in safe havens, Community Mobilization: Activate early-warning volunteers and local communication channels for rapid alert dissemination, Public Safety Precautions: Citizens must NOT attempt to walk, drive, or ride through flooded roads, bridges, or fast-flowing water courses, Drainage Maintenance: Clear blockages in drainage systems, culverts, and river mouths to facilitate unimpeded water flow, and Continuous Monitoring: State actors and the general public are advised to track daily updates from NIHSA bulletins.
