The Lagos State Government has issued a flood alert for residents across multiple zones on Monday, warning that intermittent rainfall is expected to affect at least eight distinct areas of the state throughout the day.
The commissioner for the environment and water resources, Tokunbo Wahab, released the weather advisory on Monday, covering conditions from midnight through to the following morning. He urged residents to clear drainage channels immediately and stay alert to sudden shifts in weather.
Lagos Flood Alert Covers Ikorodu, Epe and Six Other Zones
According to the advisory, residents in Ikorodu, Epe, and nearby communities face the highest early-morning exposure. Rainfall is expected over those areas from midnight into the early hours, with temperatures between 24°C and 26°C and light southwesterly winds prevailing.
Wahab said the daytime picture is equally unsettled. Temperatures are forecast to climb between 24°C and 28°C, with cloudy to partly cloudy skies interrupted by brief sunshine and rain. The areas named for daytime showers include Ikorodu, Kosofe, Somolu, Epe, Ibeju-Lekki, Eti-Osa, and Lagos Island.
For the evening, the commissioner said conditions would ease somewhat. Partly cloudy skies and temperatures between 26°C and 27°C are expected from sunset through to midnight, with no significant rain projected for that window.
Wahab’s advisory carried a direct warning to residents. “Residents are advised to keep drainage channels clear and remain alert for sudden changes in weather conditions,” he stated.
Blocked Drains Remain Top Flooding Risk in Lagos Communities
Lagos enters its most intense rainy season period between June and September each year. During this stretch, heavy downpours frequently trigger flash floods, especially in low-lying communities where drainage infrastructure is either inadequate or blocked by waste.
Authorities have repeatedly identified blocked drainage channels as a leading cause of urban flooding across the state. The Lagos State Government has stepped up canal desilting operations and enforcement action against residents and commercial operators who dump refuse into waterways.
Despite those efforts, informal waste disposal into drains remains widespread in several parts of the metropolis. The government has linked illegal dumping directly to the flooding that affects thousands of households each rainy season.
Monday’s advisory is part of a pattern of regular weather communications the state has adopted in recent years. Officials issue these updates to help residents and motorists adjust their movement and take precautions before conditions deteriorate.
The frequency of such advisories has increased as the government seeks to reduce the disruption and economic losses that severe wet-season flooding can cause across both residential and commercial parts of the city.
What Residents Must Do Before the Rains Hit
Wahab’s instructions are specific. Drainage channels around homes and business premises must be kept free of refuse. Residents in the named zones, particularly Ikorodu, Epe, Ibeju-Lekki, and Eti-Osa, are expected to act before the early-morning window when the first rains are projected.
The commissioner did not specify any emergency response measures beyond the advisory, and the state government did not announce any road closures or traffic management changes in connection with Monday’s forecast. Details on any wider operational response were not immediately available.
For low-lying communities that have experienced repeat flooding in previous seasons, the advisory carries particular weight. Those areas tend to bear the heaviest impact when drainage systems are overwhelmed, and recovery from flash floods can take days.
The Lagos State Government has consistently maintained that residents share responsibility for flood prevention. Officials have argued that blocked drains caused by illegal waste disposal undermine state investment in drainage infrastructure.
Residents are encouraged to report blocked public drains to the Ministry of the Environment and Water Resources. The government has not confirmed whether enforcement officers will be deployed specifically on Monday in response to the forecast.
For motorists, the advisory signals the likelihood of surface water on roads, particularly in low-lying corridors connecting the affected zones. Travel disruptions during and immediately after heavy downpours are common in those areas during the rainy season.
The state government said it will continue to issue updates as weather conditions develop through the day.
