The Lagos State Government has said the flash flooding currently being experienced in parts of the city is due to increased tidal levels from both the Atlantic Ocean and the Lagos Lagoon.

According to the Commissioner of the Environment and Water Resources, Tokunbo Wahab, the situation is a natural phenomenon, known as lock up, saying it occurs when high tide temporarily prevents rainwater from discharging into the sea.

He said as a result of the lock up, stormwater backs up, leading to flash floods in low-lying areas.

“We assure you that once the tide recedes, within 1–2 hours after the rain stops, the floodwater will naturally drain off,” Wahab posted on X on Tuesday.

“We appeal to all residents to remain calm and avoid panic. Our emergency response and drainage maintenance teams are actively monitoring the situation.”

The commissioner urged residents not to dispose waste into drains and gutters, stressing that such actions block water flow and worsen flooding.

“Proper waste disposal is a civic responsibility we must all uphold to ensure a flood-resilient Lagos.

“Let’s continue to work together for a cleaner, safer, and more sustainable environment,” he said.
