The Lagos State Government has urged residents to remain calm following over 12 hours of continuous rainfall, assuring the public that resilient infrastructure is in place to manage flash flooding across the state.
In a statement issued on Monday, the Commissioner for the Environment and Water Resources, Mr. Tokunbo Wahab, disclosed that a fresh weather advisory from the Nigerian Meteorological Agency (NiMet) forecasts heavy rainfall and thunderstorms across the state over the next three days.
Mr. Wahab noted that some areas may experience flash flooding due to the limitations of the existing drainage systems in handling intense run-off from the prolonged downpour.
“Lagos, being a coastal city, is particularly vulnerable to flash floods due to rising water levels in the lagoon and the effects of climate change,” he explained.
“During heavy rainfalls, tidal locks can occur, preventing stormwater from discharging into the lagoon and causing temporary flooding in parts of the city.”
He cautioned residents in low-lying areas and communities near rivers and lagoons to remain alert, warning that flash floods in such areas may come with strong currents.
In light of the ongoing school holiday, the Commissioner urged parents and guardians to closely monitor their children and prevent them from playing in the rain or attempting to swim in flooded areas.
He also reinforced earlier advisories to motorists and pedestrians, warning them against walking or driving through flooded streets, which may result in vehicle submersion or loss of life.
Mr. Wahab further warned against the improper disposal of waste, particularly into drainage channels during rainfall.
“Such actions not only block the drains but also worsen flash flood incidents.
There are consequences for these irresponsible acts,” he said.
He added that the government is intensifying its year-round drainage cleaning efforts and has awarded contracts for the construction and concrete lining of additional drainage channels to improve water flow and flood management.
“However, when there is exceptionally heavy rainfall, like what we’ve seen in the last 12 hours, collaborative efforts from both government and residents are vital to minimize the impact,” the Commissioner concluded.
