LAGOS — The Lagos State Government has directed residents living in low-lying and flood-prone communities to relocate temporarily to higher ground following a seven-day flood alert issued by the Nigerian Hydrological Services Agency (NiHSA).
Commissioner for Environment and Water Resources Tokunbo Wahab announced the directive in a statement on Monday, September 21, 2026. The advisory, covering September 19 to 25, warns of rising river levels that could trigger flooding across vulnerable parts of the state.
Lagos is among 15 states flagged in the national alert, which places more than 8,000 communities and 4,500 schools at risk of inundation.
Wahab said the state government is treating the NiHSA warning with utmost seriousness and has intensified monitoring of riverine, low-lying, and flood-prone locations. He urged residents not to delay action until floodwaters rise.
“We are urging Lagosians, particularly those living in flood-prone and low-lying areas, not to take this warning lightly. When the signs point to danger, the safest decision is to move early. No property is worth risking a life,” Wahab stated.
Vulnerable areas identified include Eti-Osa, Lagos Island, Oke-Ira Nla in Ajah, Kirikiri, Ilaje Waterfront Jetty, and Jetty Terminal B. Communities along the Ogun River and downstream of Isheri Olofin that should remain on high alert include Isheri North, Kara, Itowolo, Ajegunle, Majidun, Ogolonto, and parts of Agboyi, among others.
Residents living near rivers, lagoons, wetlands, drainage channels, and other water bodies were advised to monitor official forecasts closely and prepare for temporary relocation if flooding becomes imminent. The government also cautioned against walking or driving through flooded roads, bridges, or fast-moving water, and appealed to the public to stop dumping refuse into drains, canals, and waterways, as blockages could worsen flooding and slow the recession of floodwaters.
The alert comes as Lagos enters the second phase of the rainy season, typically marked by increased rainfall, rising water levels, and tidal influences that heighten risks in low-lying zones. Some reports also linked elevated concerns to ongoing water releases from the Oyan Dam, which could affect communities along the Ogun River banks.
Wahab emphasized early preparation and temporary moves to safer ground until the peak of the current rainy period passes. The state government said it continues drainage maintenance, monitoring, and coordination with relevant agencies to mitigate impacts and protect lives and property.
Residents in the listed communities and other flood-prone settlements are urged to heed the advisory and follow updates from official channels.
