The Ogun State Government has warned residents to prepare for increased flooding as the second phase of the 2026 rainy season begins.
The warning followed forecasts from the Nigeria Meteorological Agency indicating that Ogun is among the states expected to experience significant rainfall during the period.
The state Commissioner for Environment, Ola Oresanya, said the first phase of the rainy season, which lasted from mid-March to July, brought intense rainfall and isolated flash floods to some areas, although the overall impact was relatively limited.
He attributed the situation to measures taken by the government, including public awareness campaigns, maintenance of rivers and drainage channels, and improvements in waste management.
According to the commissioner, the second phase is expected to begin in September, with Ogun projected to record about 360mm of rainfall during the month.
He warned that prolonged rainfall, possible overflow from Oyan Dam and tidal fluctuations could increase the risk of river and coastal flooding across vulnerable areas.
Residents in Isheri, Arepo, Mawere, Magboro, Akute, Warewa and parts of Abeokuta were urged to remain alert and move to safer locations where necessary.
Communities in coastal and flood-prone areas, including parts of Ogun Waterside, Ijebu East and Ipokia, were also advised to take precautionary measures.
Oresanya called on local councils, emergency agencies, community leaders and other stakeholders to strengthen flood-response preparations, monitor vulnerable locations and ensure that drainage channels remain clear.
He also urged residents to pay attention to official weather and emergency alerts, stressing that early action would help reduce the potential impact of flooding.
The state government said it would continue working with relevant meteorological, hydrological and emergency agencies to monitor weather and water conditions and respond to emerging flood risks.
