The Lagos State Government has ordered residents living in low-lying and flood-prone communities to move to higher ground following a seven-day flood warning issued by the Nigerian Hydrological Services Agency (NiHSA).
The warning covers September 19 to 25 and places Lagos among 15 states facing an increased risk of flooding as river levels rise. NiHSA’s flood forecasting system provides early warnings and monitoring of flood risks across the country.
The Brandspur News Desk reports that the Lagos warning particularly affects communities around riverine, coastal and other vulnerable areas, with residents advised to relocate before floodwaters rise rather than wait until conditions become dangerous.
Among the locations identified by the state government are parts of Eti-Osa, Lagos Island, Oke-Ira Nla in Ajah, Kirikiri near the seaport, Ilaje Waterfront Jetty and Jetty Terminal B.
The state Commissioner for the Environment and Water Resources, Tokunbo Wahab, said authorities had intensified monitoring across the affected communities and urged residents to take the forecast seriously.
Communities along the Ogun River and other waterways have also been placed on heightened alert because rainfall upstream and rising levels in connected river systems can increase downstream flooding in Lagos.

Other locations named in the advisory include Isheri North, Kara, Itowolo, Ajegunle, Majidun, Ogolonto and parts of Agboyi, particularly settlements downstream of Isheri Olofin.
The expected flooding could affect more than homes. According to the warning, rising river levels could disrupt schools, healthcare facilities, markets, farms and places of worship in vulnerable areas.
Residents in affected communities have been advised to move people, livestock and valuable belongings to safer locations where necessary. Local governments, emergency agencies and community leaders have also been directed to activate early-warning and response measures.
The government further warned residents against driving or walking through flooded roads, bridges and fast-moving water, while appealing to people to avoid dumping refuse in drains, canals and waterways.
Lagos authorities said monitoring of rainfall patterns, river levels and drainage infrastructure would continue throughout the period covered by the alert as officials work with federal agencies to track the situation.
