The Nigerian Meteorological Agency (NiMet) has issued a flash flood alert for 27 states across the country, warning residents to brace for heavy rainfall and possible flooding during the first 10 days of July.
In a weather advisory released by the agency, NiMet attributed the heightened flood risk to persistent rainfall recorded throughout June, which has left soils across many parts of the country saturated and unable to absorb additional rain.
According to the agency, the peak rainy season, which begins in July, is expected to increase the likelihood of flash floods, particularly in low-lying communities, urban centres, coastal areas and locations with poor drainage systems.
“Following widespread rainfall recorded across many parts of Nigeria in June, soils have become heavily saturated, reducing their ability to absorb additional rainfall,” NiMet stated. “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 identified 27 states that could be affected by the anticipated flooding. They 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 heavy rains could disrupt transportation, damage infrastructure, affect agricultural activities and increase the risk of waterborne diseases in vulnerable communities.
The agency noted that flooding may lead to severe traffic congestion, temporary road closures and reduced visibility for motorists and air travel. It also warned that strong winds accompanying the storms could damage electricity infrastructure and telecommunications facilities, resulting in localized power outages.
Farmers were advised to take precautionary measures as excessive rainfall and waterlogged farmlands could affect crop production during the planting season.
NiMet also expressed concern over potential public health risks, noting that stagnant floodwaters could create conditions favourable for outbreaks of waterborne diseases if proper sanitation measures are not maintained.
The agency urged residents, state governments and emergency management agencies to take proactive steps to reduce the impact of flooding by clearing drainage channels, removing refuse blocking waterways and ensuring stormwater systems remain unobstructed.
Motorists were advised to exercise caution during periods of heavy rainfall and avoid driving through flooded roads or fast-moving water.
NiMet further encouraged Nigerians to monitor regular weather forecasts and heed safety advisories throughout the peak rainy season as authorities continue to monitor rainfall patterns across the country.
