The Lagos State Government has called for calm following over 12 hours of continuous rainfall that triggered flash flooding in parts of the metropolis.

In a statement on Monday, the Commissioner for the Environment and Water Resources, Tokunbo Wahab, urged residents to remain vigilant and prioritise safety. He assured the public that the state’s flood management infrastructure is designed to handle such weather conditions.

The appeal followed a weather advisory from the Nigerian Meteorological Agency (NiMET), which forecasted continued heavy rainfall and thunderstorms across Lagos for the next three days.

Wahab explained that the prolonged downpour may temporarily overwhelm some major drainage channels, especially in low-lying and waterfront areas.

“Being a coastal city, Lagos often experiences rising lagoon water levels during intense rainfalls. This can cause tidal locks, hampering the effective discharge of stormwater,” he said.

The commissioner warned that communities close to rivers and lagoons may experience high-current flash floods and advised parents to keep children indoors and away from flooded areas.

He also cautioned motorists and pedestrians against attempting to cross flooded roads, as they risk being swept away or trapped in submerged vehicles.

Wahab emphasised the dangers of indiscriminate waste disposal, particularly during the rainy season. He warned that dumping refuse into drainage channels obstructs water flow and worsens flooding, adding that violators would face legal sanctions.

Highlighting the government’s proactive efforts, Wahab said the state continues to carry out year-round clearing of drainage systems and has awarded new contracts for the concrete-lining of drains to improve stormwater flow and resilience.

“However, in situations where there is more than usual rainfall, as experienced in the last 12 hours, collective responsibility is needed to mitigate the impact,” the statement read.

The government assured residents that emergency response teams are on standby, while urging all Lagosians to comply with safety advisories and remain alert throughout the rainy season. (The Nation)
