NiMet Raises Fresh Flood Alarm For Lagos, Oyo, 17 Other States

The Nigerian Meteorological Agency (NiMet) has issued a fresh warning over the likelihood of flash floods in 19 states across the country as heavy early rains begin to intensify in several regions.

In a weather advisory released on Thursday, the agency explained that the risk of flooding has increased due to prolonged dry spells that left the soil compact and unable to absorb large volumes of rainfall effectively. The development, NiMet noted, could trigger excessive surface runoff capable of overwhelming drainage systems and inundating communities.

According to reports monitored by Ireporter Online, the states identified as vulnerable to the looming floods include Zamfara, Nasarawa, Kwara, Oyo, Lagos, Ogun, Ekiti, Delta, Imo, Anambra, Enugu, Ebonyi, Akwa Ibom, Cross River, Rivers, Edo, Ondo and Bayelsa.

The agency cautioned residents in the affected areas to brace for possible disruptions and adopt preventive measures to reduce the impact of potential flooding incidents. It warned that the expected downpours could lead to submerged roads, severe traffic congestion, destruction of homes and farmlands, as well as damage to public infrastructure.

NiMet further highlighted the possibility of blocked drainage channels, power outages and interruptions to telecommunications services in vulnerable communities. The agency also raised concerns that stagnant floodwaters could increase the spread of water-borne diseases and expose residents to injuries if urgent precautions are ignored.

“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.

Residents were advised to clear drainage systems around their homes and remain alert to official weather forecasts and flood warnings. Motorists and pedestrians were equally urged to avoid flooded roads to prevent accidents and possible loss of lives.

NiMet also appealed to emergency response agencies, state governments and relevant stakeholders to strengthen preparedness efforts and improve emergency response strategies ahead of the anticipated floods.

The warning comes amid growing concerns over flooding across Nigeria after the Federal Government recently disclosed that more than 14,000 communities in 33 states and the Federal Capital Territory could face severe flooding in 2026. The alert has revived memories of previous flood disasters that displaced thousands of residents, destroyed properties and disrupted economic activities in many parts of the country.
