NiMet Issues Nationwide Alert on Heavy Rainfall, Thunderstorms, and Flood Risk from Monday to Wednesday

The Nigerian Meteorological Agency (NiMet) has warned of heavy rains, thunderstorms, and an elevated risk of flooding across various parts of the country between Monday and Wednesday, urging citizens, businesses, and relevant authorities to take precautionary measures. The forecast indicates that multiple regions—including the North-Central, South-West, South-East, and some parts of the North-East—are expected to experience intense downpours that could cause significant disruptions to daily life, damage to property, and potential loss of lives if safety guidelines are ignored.

According to NiMet’s latest bulletin, the heavy rainfall will be accompanied by strong winds and lightning, which could result in hazardous conditions for road users, farmers, and residents of flood-prone communities. The agency specifically mentioned that low-lying areas, poorly drained urban centres, and settlements near riverbanks face the highest risk of flash floods during this period. NiMet’s meteorologists have identified a convergence of moisture-laden winds from the Atlantic Ocean and unstable atmospheric conditions as the main drivers of the predicted weather pattern.

The statement warned that prolonged or intense rainfall within the forecast window may lead to overflowing of drainage systems, accumulation of water on major roads, and possible collapse of vulnerable infrastructure. Motorists were advised to exercise extreme caution by reducing speed during storms, turning on headlights in low-visibility situations, and avoiding flooded routes entirely. “We urge Nigerians to stay informed and prioritise safety as the weather conditions during this period could be severe,” the agency stressed.

NiMet further explained that the thunderstorms could cause strong downdrafts capable of uprooting trees, damaging rooftops, and toppling power lines, potentially resulting in power outages in some areas. Communities have been encouraged to secure outdoor items, reinforce weak structures, and avoid sheltering under trees during lightning activity. The agency also warned against indiscriminate dumping of refuse into drainage channels, noting that blocked waterways significantly increase the risk of urban flooding.

In preparation for the severe weather, the National Emergency Management Agency (NEMA) confirmed that its disaster response teams have been placed on high alert. NEMA’s spokesperson said the agency is working with state emergency management agencies, local councils, and community leaders to ensure rapid response in case of flooding or other emergencies. “We have pre-positioned resources and are ready to activate evacuation protocols where necessary. We appeal to residents to heed all warnings and cooperate with authorities to save lives,” the spokesperson added.

Residents in states with historically high flood incidents—such as Lagos, Ogun, Rivers, Anambra, Benue, and Niger—have been advised to pay particular attention to the forecast. Farmers were reminded to take steps to protect seedlings, livestock, and farm equipment from excessive water damage, as the predicted weather could impact agricultural activities. NiMet also advised fisherfolk and boat operators to avoid venturing into open waters during periods of high winds and heavy rain.

Experts have noted that the combination of heavy rainfall and poor urban drainage systems is a recurring challenge for many Nigerian cities. Environmentalists say years of unregulated development, inadequate waste management, and lack of drainage maintenance have worsened the effects of seasonal rains. Climate change has further complicated the situation, with shifting weather patterns increasing the frequency and intensity of extreme weather events such as floods and windstorms.

Public health officials have also raised concerns about the possible health implications of flooding, including the spread of waterborne diseases like cholera and typhoid. Standing water can become a breeding ground for mosquitoes, increasing the risk of malaria outbreaks. The Ministry of Health has urged communities to ensure proper sanitation, boil drinking water where necessary, and seek medical attention promptly if symptoms of illness occur after flooding events.

Transport authorities have cautioned that travel delays should be expected, particularly on intercity highways and urban roads prone to waterlogging. Air travel may also be affected, with potential flight delays or cancellations due to low visibility and turbulent weather conditions. Commuters are encouraged to plan journeys in advance and allow extra travel time during the forecast period.

NiMet reiterated that its forecast is based on scientific modelling and real-time atmospheric monitoring, and it will continue to provide daily updates to help Nigerians prepare adequately. The agency emphasised that early warning is only effective if citizens and institutions act on the information provided. “We can significantly reduce the impact of adverse weather events if communities take our alerts seriously,” the statement read.

For communities in riverine areas, NiMet advised constant monitoring of water levels and proactive evacuation if necessary. The agency urged collaboration between local authorities and residents to identify safe shelters ahead of time, rather than waiting until flooding becomes severe. Religious leaders, civil society organisations, and the media have also been called upon to help spread the warning and encourage compliance with safety measures.

As the country braces for the forecasted heavy rains and thunderstorms, both government and non-governmental agencies stress the importance of preparedness, early action, and cooperation. While flooding during the rainy season is not unusual in Nigeria, the severity of the upcoming weather demands extra vigilance. The ability of communities to respond effectively will not only protect lives and property in the short term but will also strengthen resilience against future climate-related disasters.

In the coming days, NiMet’s forecast will remain under close watch as authorities track the movement of rain-bearing systems and update the public on any changes. Citizens are urged to follow official weather reports through radio, television, and verified online platforms, rather than relying on rumours or unverified social media claims. By staying informed and taking preventive action, Nigerians can collectively reduce the risks posed by the approaching storms and floods.
