NiMet Forecasts Three Days of Thunderstorms as Flood Risks Persist Across Nigeria

NiMet warns of thunderstorms and rainfall

The Nigerian Meteorological Agency (NiMet) has forecast three consecutive days of thunderstorms and moderate rainfall across several parts of Nigeria, with strong winds expected to precede thunderstorms in some locations.

The three-day outlook covers Monday to Wednesday and spans the northern, North-Central and southern regions, with varying levels of rainfall expected across states.

The forecast comes as several parts of the country remain vulnerable to flooding following intense rainfall, highlighting continuing risks for communities, infrastructure and properties in low-lying areas.

Thunderstorms Expected Across Northern Nigeria

NiMet expects patches of clouds across the northern region on Monday morning, followed by thunderstorms and moderate rainfall across most parts of the region later in the day.

In the North-Central region, cloudy conditions are expected during the morning, with isolated thunderstorms and moderate rainfall forecast across the Federal Capital Territory, Nasarawa, Benue, Kogi, Niger and Plateau states.

Southern states are also expected to experience cloudy conditions and rainfall, with intermittent moderate rain forecast across much of the region later on Monday.

The forecast indicates that the weather system will remain active across different parts of the country rather than being concentrated in a single region.

Rainfall to Continue Through Wednesday

NiMet expects the weather conditions to continue on Tuesday, with morning thunderstorms and light rainfall over parts of Borno, Gombe, Bauchi, Yobe, Taraba and Adamawa.

Moderate rainfall is expected across much of the northern region later in the day, while parts of the North-Central region could also experience isolated thunderstorms and moderate rain.

In the South, afternoon and evening thunderstorms with moderate rainfall are expected across Ekiti, Osun, Ogun, Ondo, Oyo, Edo, Enugu, Abia, Ebonyi, Imo, Anambra, Lagos, Delta, Bayelsa, Cross River, Akwa Ibom and Rivers states.

On Wednesday, thunderstorms and moderate rainfall are expected across parts of the North, while most of the North-Central region could experience moderate rainfall later in the day.

NiMet also forecasts intermittent rainfall across the South, with moderate rain expected over the region during the afternoon and evening.

Flood-Prone Communities Remain Vulnerable

The latest forecast is significant for the property and infrastructure sectors because intense rainfall over short periods can increase surface runoff, particularly in locations with inadequate drainage, saturated soils and low-lying terrain.

NiMet has separately identified several states, including Lagos, Oyo, Ogun, Rivers, Bayelsa, Delta, Cross River, Akwa Ibom, FCT, Benue, Kogi and Niger, among areas with potential flash-flood risks during the third dekad of September.

For property owners and developers, the risk extends beyond temporary waterlogging. Repeated flooding can damage buildings, roads, drainage infrastructure and utilities while increasing maintenance costs and affecting the long-term resilience of developments.

Weather Risks Highlight Importance of Drainage

The forecast reinforces the importance of drainage capacity in urban development.

Rapid urbanisation has increased pressure on drainage systems in many Nigerian cities, while development in flood-prone and low-lying locations can increase exposure when stormwater infrastructure does not keep pace with population and construction activity.

For housing developers, effective stormwater management therefore remains an important consideration in site selection, design and construction.

Drainage infrastructure, road levels, flood channels and proximity to waterways can all influence the long-term performance and value of residential and commercial properties.

Lagos and Other Southern States Face Continued Rainfall

Lagos is among the states included in NiMet's Tuesday afternoon and evening forecast for thunderstorms and moderate rainfall.

The latest outlook comes shortly after the Lagos State Government intensified monitoring of flood-prone communities following a separate NiHSA flood alert. The state's earlier warning identified several low-lying and riverine communities as vulnerable to flooding.

The combination of rainfall forecasts and existing flood vulnerabilities makes stormwater management particularly relevant to Lagos property development.

For developers and investors, flood exposure is increasingly becoming part of the broader assessment of location quality, infrastructure requirements and property resilience.

Construction Activity May Face Weather Disruptions

Beyond flooding, sustained rainfall and thunderstorms can affect construction schedules.

Heavy rain can disrupt excavation, concrete works, earthworks and external finishing, while waterlogged sites can complicate movement of construction equipment and materials.

Strong winds associated with thunderstorms can also create additional safety risks around construction sites, particularly where workers operate at height or where temporary structures and unsecured materials are present.

Construction companies therefore need to incorporate weather conditions into project scheduling and site-safety planning.

NiMet Advises Aviation Operators to Monitor Weather Conditions

NiMet has also advised airline operators to obtain airport-specific weather reports and flight documentation to support operational planning.

Thunderstorms and strong winds can affect aviation operations, making localised weather information important for flight scheduling and safety.

The advisory highlights the broader economic effects of weather conditions, which can extend from residential communities and construction sites to transport and logistics infrastructure.

Flood Resilience Gains Importance for Property Markets

For Nigeria's housing market, increasingly frequent weather alerts underscore the need to integrate climate and flood resilience into development planning.

This includes protecting natural drainage channels, improving stormwater infrastructure, enforcing appropriate building and land-use standards and avoiding development patterns that increase exposure to flood hazards.

NHM's recent reporting on Lagos' flood-prone communities has similarly highlighted the importance of drainage, urban planning and protection of natural flood-control systems to the long-term resilience of property markets.

The latest NiMet forecast does not mean that every location listed will experience flooding. Rainfall intensity, drainage capacity, terrain and local conditions will determine the actual impact in individual communities.

Outlook

NiMet's three-day outlook places much of Nigeria under the prospect of thunderstorms and moderate rainfall through Wednesday, with strong winds potentially preceding storms in affected areas.

For the housing and real estate sector, the immediate concern is the potential disruption to construction, transport and urban activity, particularly in flood-prone locations.

The wider implication is the growing importance of resilient infrastructure and climate-aware development as rainfall patterns continue to create risks for Nigeria's rapidly expanding urban areas.
