ABUJA — The Nigeria Hydrological Services Agency (NiHSA) has issued a national flood advisory placing 33 states at high risk of riverine flooding between August 19 and 25, 2026, warning vulnerable communities to take immediate precautionary measures.
The Director-General and Chief Executive Officer of NiHSA, Umar Ibrahim Mohammed, said the advisory followed rising river levels at 92 gauging stations across the country, raising concerns over possible flooding in communities along river channels, low-lying areas and floodplains.
Among the key locations under close monitoring are Katsina Ala on the Katsina Ala River, Dadin Kowa, near the Gombe-Biu Bridge on the Gongola River, and Sokoto at the Illela Bridge on the Rima River.
Mohammed urged residents of flood-prone communities not to wait until floodwaters rise before taking action, advising them to move people, livestock and valuables to safer and higher ground where necessary.
“We are calling on communities in vulnerable areas not to wait until flooding occurs before taking action,” he said. “Where necessary, people, livestock and valuables should be moved immediately to safer and higher ground. Early action saves lives and reduces losses.”
He also called on state governments, local authorities, emergency management agencies, traditional institutions and community leaders to strengthen preparedness and activate local early-warning systems.
The NiHSA boss urged relevant authorities to pre-position relief materials, water-treatment supplies and first-aid equipment, while identifying safe shelters for residents who may need to evacuate.
Members of the public were further warned against crossing flooded roads, bridges and fast-moving water either on foot or in vehicles.
“Floodwater can be deceptive and extremely dangerous. We strongly advise the public not to take unnecessary risks by attempting to cross flooded roads, bridges or waterways,” Mohammed cautioned.
He stressed the need for the immediate clearing of blocked drainage channels and river outlets to keep waterways free from obstructions during the period of heightened flood risk.
Mohammed also urged communities to mobilise early-warning volunteers to help disseminate official information and support vulnerable residents in taking timely action.
He reiterated NiHSA’s commitment to providing timely hydrological information and early warnings to support disaster preparedness and protect lives and property.

“Flood preparedness is a shared responsibility. Let us act early, stay informed and protect lives and livelihoods,” he said.
