NIHSA Issues Fresh Flood Alert for 17 States, Urges Immediate Evacuation
The Nigeria Hydrological Services Agency (NIHSA) has issued a medium flood risk advisory for 17 states. It warns of imminent flooding along major river channels between July 21 and July 27, 2026. According to the agency, rising water levels at monitoring stations nationwide triggered the alert.
What Triggered the Warning
NIHSA Director-General Umar Mohammed said river levels at key stations have exceeded warning thresholds. These include Saminara on the Karam River and Waya Dam Site on the Waya River. Additionally, the agency says 16 gauging stations across the country are currently recording elevated water levels. “Communities along the primary channels face imminent localised flooding,” Mohammed said. He urged state governments and residents on floodplains to evacuate immediately.
States and Communities at Risk
Bauchi, Edo, Imo, Kaduna, Plateau, and Benue lead the list. Meanwhile, 11 other states are also flagged for varying flood risk. The numbers are steep in places. For instance, Imo State alone has 415 communities, 423 schools, and 198 health facilities identified as vulnerable. Bauchi has nearly 1,900 communities at risk, alongside 145 schools and 101 health facilities.
What Happens Next
NIHSA has directed NEMA, state emergency agencies, and local authorities to activate emergency preparedness measures immediately. Recommended steps include evacuating residents and livestock, pre-positioning relief supplies, and activating community-based early warning systems.

Why This Matters for Real Estate
This is the latest in a string of flood warnings this rainy season, following earlier alerts covering 26 and even 33 states. For developers and property owners in the affected corridors, each advisory adds to a growing case. Flood exposure needs to shape where and how Nigeria builds, not just how it responds after water rises.
Conclusion
NIHSA has given specific numbers, specific rivers, and a specific window. Whether the response matches that specificity, in evacuation, in enforcement, in planning, will determine how many of these communities avoid becoming next month’s damage report.
