The Minister of Water Resources and Sanitation, Prof. Joseph Utsev, says no fewer than 33 states and the FCT will experience flooding in 2026, with 14,118 communities identified as high-risk nationwide.
Utsev disclosed this in Abuja on Wednesday at the public presentation of the 2026 Annual Flood Outlook (AFO) by the Nigeria Hydrological Services Agency (NIHSA).
He said the high-risk communities were located in 266 Local Government Areas (LGAs) based on scientific forecasts and hydrological assessments.
The states to be affected, according to him are Abia, Adamawa, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, Enugu, Gombe, Imo, Jigawa, Kaduna and Kano.
Others include Kebbi, Kogi, Kwara, Lagos, Nasarawa, Niger, Ogun, Ondo, Osun, Oyo, Plateau, Rivers, Sokoto, Taraba, Yobe and Zamfara, including the FCT.
The minister said 15,597 communities in 405 LGAs across 35 states would face moderate flood risk, while Ekiti remained the only state not affected.
He said 923 communities in 77 LGAs across 24 states fell within the low flood risk category.
“States in this category include Adamawa, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, Jigawa, Kaduna, Kano, Kebbi, Kogi, Nasarawa, Niger, Ogun, Ondo, Osun, Oyo, Sokoto, Taraba and Zamfara,” he said.
He warned of possible flash and urban flooding in Abuja, Lagos, Port Harcourt, Ibadan and Kano.
He said coastal and riverine flooding is expected in Bayelsa, Cross River, Delta, Lagos, Ogun, Rivers and Ondo States due to rising sea levels and tidal surges.
“The AFO is not just a scientific report; it is a call to action. Early warning saves lives and reduces economic losses,” he emphasised.
Utsev attributed increasing flood incidents to climate variability, rapid urbanisation, inadequate drainage infrastructure and poor land-use practices.
He revealed that the Federal Government was strengthening hydrological monitoring through improved data systems, automated river gauges and advanced modelling techniques.
The minister said collaboration with the Nigerian Meteorological Agency (NiMet) and the National Emergency Management Agency (NEMA) were being enhanced to improve forecast accuracy and early warning dissemination.
The minister urged state governments to integrate flood risk considerations into land-use planning, urban development and infrastructure design.
He also called for improved drainage systems, effective floodplain management and stronger community preparedness to minimise impacts.
