Lagos residents living in areas close to rivers, waterways and other locations that easily collect water have been advised to move to safer places as the state prepares for another period of heavy rainfall.
The warning was issued by the Lagos State Government after the Nigerian Hydrological Services Agency (NiHSA) released a new seven-day flood alert covering September 19 to 25, 2026. The alert includes Lagos and 14 other states.
Lagos Commissioner for the Environment and Water Resources, Tokunbo Wahab, said residents in vulnerable communities should not wait until water enters their homes before taking action. He encouraged those at risk to temporarily move to higher ground and remain there while the danger continues
Some of the areas identified include Eti-Osa, Lagos Island, Oke-Ira Nla in Ajah, Kirikiri, Ilaje Waterfront Jetty and Jetty Terminal B. Communities around Isheri North, Kara, Itowolo, Ajegunle, Majidun, Ogolonto and parts of Agboyi have also been advised to stay on high alert.
Wahab explained that Lagos usually experiences another period of intense rainfall from September. Rising river levels, heavy rain and tidal activity can increase the chances of flooding, especially in low-lying and waterfront communities.
He also warned residents against walking or driving through floodwater because fast-moving water can be dangerous.
The commissioner urged Lagosians to pay attention to official warnings and make arrangements to move people, animals and valuable belongings to safer locations when necessary.
He further appealed to residents to stop throwing refuse into drains, canals and waterways, noting that blocked drainage channels can make flooding worse
