The Nigerian Meteorological Agency (NiMet) has issued a flash flood risk alert for 27 states across the country, warning that heavy rainfall expected between July 1 and July 10, 2026, could trigger flooding in several vulnerable communities.
According to the agency, the widespread rainfall recorded in June has left the soil heavily saturated, reducing its ability to absorb additional water. This, NiMet said, significantly increases the likelihood of flash floods, particularly in low-lying communities, urban centres, coastal areas, and locations with poor drainage systems.
The states identified as being at heightened 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 anticipated heavy rainfall could result in localized flash flooding, disrupting transportation, causing traffic gridlock and road closures, while also affecting electricity supply and telecommunications services in some areas.
The agency further cautioned that reduced visibility may pose risks to motorists and aviation operations, while prolonged waterlogging could damage farmlands, destroy crops, and affect critical infrastructure, including roads, bridges, and drainage systems.
It also raised concerns over the possibility of waterborne disease outbreaks, noting that stagnant floodwaters could pose serious public health risks if proper sanitation measures are not observed.
To reduce the impact of the expected flooding, NiMet advised residents to stay updated with official weather forecasts, clear drainage channels of refuse, secure loose outdoor items, and avoid walking or driving through flooded roads.
The agency stressed that early preparedness, public awareness, and prompt response remain essential to mitigating the effects of flash floods during the peak of the 2026 rainy season.
NiMet also called on the National Emergency Management Agency (NEMA), State Emergency Management Agencies (SEMAs), local governments, community leaders, and other relevant stakeholders to strengthen emergency preparedness and response measures to safeguard lives and property.
As the rainy season intensifies, Nigerians, particularly those living in flood-prone areas, are urged to remain vigilant and adhere to safety advisories issued by relevant authorities.
