NiMet warns 27 Nigerian states at risk of flash flooding

The Nigerian Meteorological Agency (NiMet) has warned that 27 states across Nigeria are at risk of experiencing flash flooding in the coming days as the country enters the peak of the rainy season.

The warning was contained in NiMet's flash flood risk alert for the first dekad of July, covering the period from July 1 to July 10.

According to the agency, persistent rainfall recorded across many parts of the country in June has left the soil heavily saturated, significantly reducing its ability to absorb more rain.

"Following widespread rainfall recorded across many parts of Nigeria in June, soils have become heavily saturated, reducing their ability to absorb additional rainfall.

"As July 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," the agency said.

NiMet listed the states most likely to experience flash flooding as 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.

The agency also warned that flooding could disrupt electricity and telecommunications services in affected areas, while heavy rainfall may reduce visibility for motorists and aviation operations.

It further cautioned that farmlands could become waterlogged, leading to crop losses, while roads, bridges, drainage systems, and other public infrastructure may also suffer damage.

Health authorities were advised to remain alert due to the increased risk of waterborne diseases associated with stagnant floodwaters and poor sanitation.

To reduce the impact of the expected flooding, NiMet urged Nigerians to monitor weather forecasts and flood advisories, keep drains and waterways free of refuse, secure loose outdoor items, reinforce vulnerable structures, and avoid walking or driving through floodwaters.

The agency 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.

NiMet stressed that early planning and timely action remain the most effective ways to minimise the devastating effects of flash flooding.
