More than 8,000 communities and 4,500 schools across 15 states are at risk of flooding between September 19 and 25, according to the latest National Flood Advisory issued by the Nigeria Hydrological Services Agency.

The agency warned that rising river levels could trigger flooding in vulnerable communities, exposing schools, healthcare facilities, markets, religious buildings and farmlands to possible inundation.

The warning was contained in the agency’s National Flood Advisory issued on Saturday by its Director-General and Chief Executive Officer, Arch Umar Mohammed.

The affected states include Imo, Cross River, Delta, Ebonyi, Benue, Anambra, Akwa Ibom, Edo, Enugu, Bayelsa, Kogi, Abia, Taraba, Rivers and Lagos.

Mohammed said rising river levels were expected to trigger flooding in several communities, putting schools, healthcare facilities, markets, farms and religious buildings at risk.

He urged affected state governments to urgently relocate residents living in vulnerable communities to safer locations ahead of the forecast.

He said, “High riverine flood risk is forecast for the next seven days across Imo, Cross River and 13 other states.

Rising river stages are expected to cause flooding.

“Communities on the floodplain should prepare to move to higher ground. Stations include Obubra, Itigidi and Epento on the Cross River.”
