This warning follows a seven-day flood risk alert from the Nigerian Hydrological Services Agency (NiHSA), effective from September 19 to 25. Tokunbo Wahab, the Lagos Commissioner for Environment and Water Resources, highlighted this alert in a statement on September 21, noting its critical importance for those residing in low-lying, riverine, coastal, and flood-prone areas.

Specific communities identified include Eti-Osa, Lagos Island, Oke-Ira Nla in Ajah, Kirikiri, Ilaje Waterfront, and Jetty Terminal B. The advisory also extends to settlements along the Ogun River and additional vulnerable areas like Isheri North, Kara, Itowolo, Ajegunle, Majidun, Ogolonto, and parts of Agboyi. Wahab particularly remarked on the necessity for families in these at-risk locations to act preemptively, stressing, “No property is worth risking a life.”

NiHSA’s flood risk warning signifies heightened river levels and intense rainfall, which could lead to significant overflow into nearby floodplains and waterways, exposing Lagos’s susceptibility, especially in regions adjacent to rivers and low-lying neighborhoods. The government is actively enhancing its monitoring of rainfall and river conditions, collaborating with relevant agencies to bolster flood prevention and response measures.

To mitigate potential hazards, Wahab instructed residents to keep drains and waterways clear of debris, avoid traversing flooded regions, and adhere to official flood forecasts and advisories. He concluded by encouraging Lagosians to remain calm and responsive to safety instructions as the situation is continuously being monitored by local authorities.
