The Federal Government has placed 17 states on flood alert, urging residents in vulnerable communities to evacuate immediately as rising river levels increase the risk of severe flooding over the next seven days.
The warning was issued by the Nigeria Hydrological Services Agency (NIHSA) in its latest National Flood Advisory covering July 21 to July 27, 2026. According to the agency, water levels at several major rivers have exceeded critical thresholds, raising the likelihood of localized flooding in floodplains and riverside communities.
NIHSA said the affected states include Bauchi, Benue, Edo, Imo, Kaduna, Plateau and 11 others. While Lagos was not listed among the 17 states in the latest advisory, authorities in the state have separately warned residents to remain vigilant following recent flash floods caused by heavy rainfall and blocked drainage channels.
Director-General of NIHSA, Umar Ibrahim Mohammed, said monitoring stations along major rivers have recorded water levels above warning limits, making immediate action necessary to reduce the impact on lives and property.
The agency has directed the National Emergency Management Agency (NEMA), state emergency agencies, local governments and community leaders to relocate residents, livestock and valuables from flood-prone areas while also positioning relief materials in anticipation of possible emergencies. It also advised residents to avoid driving or walking through flooded roads and to stay updated through official flood bulletins.
Nigeria experiences its peak rainy season between July and September, with flooding becoming more frequent in recent years due to heavier rainfall, poor drainage systems and rapid urbanization. Authorities say early evacuation remains the safest way to minimize casualties as the rains continue.
