The Nigerian Meteorological Agency (NiMet) has warned that 19 states across the country may witness flash flooding in the coming days following the onset of heavy early rains.

‎In an advisory issued on Thursday, the agency explained that the anticipated flooding could become severe because prolonged dry conditions had left the soil hardened, reducing its ability to absorb water effectively.

According to NiMet, the situation may result in increased surface runoff capable of overwhelming drainage channels and flooding communities.

The agency listed the states likely to be affected as Zamfara, Nasarawa, Kwara, Oyo, Lagos, Ogun, Ekiti, Delta, Imo, Anambra, Enugu, Ebonyi, Akwa Ibom, Cross River, Rivers, Edo, Ondo and Bayelsa.

NiMet warned that residents in the affected areas should prepare for possible disruptions and take precautionary measures to reduce the impact of the floods.

The agency noted that the expected flash floods could lead to flooded roads, traffic gridlocks and destruction of homes, farmlands and critical infrastructure.

It also warned of blocked drainage systems, possible power outages and disruptions to telecommunications services in vulnerable communities.

NiMet further stated that the flooding may increase the risk of injuries and outbreaks of water-borne diseases if urgent preventive steps are not taken.

“The flooding risk is heightened because dry and hardened soils will prevent water from soaking properly into the ground, leading to increased surface runoff,” the advisory stated.

The weather agency advised residents to clear blocked drainages around their homes and remain attentive to official weather forecasts and flood alerts.

Motorists and pedestrians were also cautioned against driving or walking through flooded roads to avoid accidents and loss of lives.

NiMet called on emergency agencies, state governments and other stakeholders to improve preparedness and strengthen emergency response mechanisms to minimise possible flood-related disasters.

Naija News report that the Federal Government had recently warned that no fewer than 14,118 communities in 33 states and the Federal Capital Territory could experience severe flooding in 2026.

The warning heightened fears of a repeat of the devastating floods recorded in several parts of the country in previous years, which displaced thousands of residents, destroyed property and disrupted economic activities.
