The Nigerian Meteorological Agency (NiMet) has issued a flash flood alert for the first 10 days of July, warning that persistent and widespread rainfall could trigger flooding across 27 states of the federation.
In its latest weather advisory covering July 1 to July 10, the agency said the country is entering the peak phase of the rainy season, with already saturated soils increasing the likelihood of flash floods in vulnerable areas.
According to NiMet, the continuous rainfall experienced in June has significantly reduced the capacity of the ground to absorb additional water.
“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 stated.
The weather agency identified 27 states that are expected to face elevated flood risks during the period.
The affected states are 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 heavy rainfall could cause severe disruptions to transportation, agriculture, infrastructure, public utilities and public health if precautionary measures are not taken.
The agency noted that intense downpours could result in localised flooding, leading to traffic congestion, road closures and interruptions to transportation networks.
It also cautioned that electricity and telecommunications services could be temporarily affected in flooded communities.
In addition, poor visibility caused by heavy rainfall may pose safety risks to motorists and disrupt aviation operations.
NiMet further warned that excessive rainfall could waterlog farmlands, resulting in crop damage and losses, while roads, bridges, drainage systems and other public infrastructure may also suffer significant damage.
The agency added that stagnant floodwaters could increase the spread of waterborne diseases, urging health authorities to remain alert throughout the period.
To minimise the impact of the anticipated flooding, NiMet advised residents to monitor official weather forecasts and flash flood advisories regularly.
It also encouraged the public to keep drains, gutters and waterways free of refuse to allow the free flow of water, secure outdoor objects, reinforce vulnerable structures and avoid walking or driving through floodwaters.
The agency called on the National Emergency Management Agency (NEMA), State Emergency Management Agencies (SEMAs), community leaders and other relevant stakeholders to strengthen preparedness and emergency response measures ahead of the expected rainfall.
NiMet emphasised that early planning and prompt action remain the most effective strategies for reducing the effects of flash flooding.
“Early preparedness and timely action remain essential in reducing the impacts of flash flooding,” the agency stated.
Reiterating the importance of public awareness, NiMet urged Nigerians to remain vigilant and respond promptly to weather advisories.
“An informed community is a prepared community. Know the risks and Act Early,” it concluded.
