The Nigerian Meteorological Agency (NiMet) has warned that 27 states face a high risk of flash flooding between this month as the country enters the peak of its rainy season.
In an advisory issued by the agency said persistent rainfall recorded last month had left soils across many parts of Nigeria heavily saturated, increasing the likelihood of flooding in vulnerable communities.
“Following widespread rainfall recorded across many parts of Nigeria last month, soils have become heavily saturated, reducing their ability to absorb additional rainfall,” NiMet said.
It added: “As this month marks the beginning of the peak rainy season, the risk of flash flooding is expected to increase, particularly in low-lying, urban, coastal, and poorly drained areas.”
According to the agency, the states at risk include Taraba, Sokoto, Borno, Zamfara, Kebbi, Katsina, Kaduna, Nasarawa, Plateau, Adamawa, Kwara, Kogi, Oyo, Ogun, Lagos, Osun, Ekiti, Delta, Edo, Abia, Imo, Anambra, Enugu, Akwa Ibom, Cross River, Rivers and Bayelsa.
NiMet warned that the expected heavy rainfall could disrupt transportation, damage infrastructure, affect farming activities and increase public health risks.
“The heavy rainfall could trigger localized flooding, resulting in traffic gridlock, road closures and disruptions to transportation,” the agency said.
It also cautioned that temporary power and telecommunications outages could occur in affected areas, while poor visibility during intense rainfall could endanger motorists and aviation operations.
The agency further warned that waterlogged farmlands could lead to crop losses, while roads, bridges, drainage systems and other public infrastructure may suffer significant damage.
NiMet urged health authorities to remain alert to the increased risk of waterborne diseases linked to stagnant floodwaters and poor sanitation.
To reduce the impact of the expected flooding, the agency advised residents to monitor weather forecasts and flood alerts, clear drains and waterways, secure loose outdoor objects, reinforce vulnerable structures, and avoid walking or driving through floodwaters.
It also called on the State Emergency Management Agencies (SEMAs), the National Emergency Management Agency (NEMA), community leaders and other stakeholders to strengthen preparedness and response efforts.
“Early preparedness and timely action remain essential in reducing the impacts of flash flooding,” NiMet said.
The agency concluded with a renewed call for vigilance, saying: “An informed community is a prepared community. Know the risks and Act Early.”
