The Nigerian Meteorological Agency (NiMet) has issued a nationwide weather alert, warning of widespread thunderstorms and heavy rainfall in the coming days. But in Lagos, a coastal megacity particularly prone to flooding, the state government has raised the alarm, urging residents—especially those in low-lying and flood-prone areas—to take immediate precautions.
In a proactive response, the Lagos State Government directed residents in floodplains to relocate to safer, higher ground, warning of possible flash floods, collapsed buildings, traffic disruption, health hazards, and loss of lives if care isn’t taken. Temporary shelters have been prepared at various relief camps across the state to support those who may be affected.
Above Normal Rainfall Expected in 2025
Commissioner for the Environment and Water Resources, Mr. Tokunbo Wahab, reminded the public that Lagos is forecasted to receive above-normal rainfall in 2025—an estimated 1,952mm. He warned that strong winds at the beginning and end of the rainy season could pose additional risks, including damage to infrastructure, flight delays, and economic losses.
The forecast is driven by the neutral phase of the El-Niño Southern Oscillation (ENSO), which could result in an early onset, prolonged duration, and delayed end to the rainy season. Wahab stressed that rainfall from neighbouring states and potential dam releases would be closely monitored.
June 13 Flooding Serves as Early Warning
Wahab cited the torrential rain on June 13 as a clear indication of what lies ahead, pointing out that heavy rainfall in some areas led to flash floods and high water currents. He advised residents without urgent need to leave their homes during such weather to remain indoors for safety.
He also appealed to parents to keep children away from floodwaters and discouraged anyone from swimming or playing in them.
Flood Mitigation and Government Preparedness
Wahab assured Lagosians of ongoing efforts to mitigate flood risks. These include:
- Year-round drainage maintenance
- Efficient solid waste management
- Monitoring of Ogun River through collaboration with Ogun-Oshun River Basin Development Authority (OORBDA)
- Strengthened Flood Early Warning Systems (FEWS)
- Community-level emergency preparedness via LASEMA
The state is also working with the Lagos State Signage and Advertisement Agency (LASAA) to ensure billboards and masts are secured, especially during expected high wind periods.
High-Risk Areas Being Monitored
Communities such as Agiliti, Agboyi, Itowolo, Ajegunle, Iwaya, Owode, Makoko, Badia, Ijora, Isaalu, and Shibiri are under close surveillance for potential river overflow and flash flooding.
“We will notify such residents at the appropriate time if evacuation becomes necessary,” Wahab said, while warning motorists to reduce speed during heavy rainfall to avoid accidents.
Public Appeal and Enforcement
Wahab urged residents to refrain from dumping refuse into drains, constructing buildings along drainage channels, or engaging in any acts that worsen flooding. He encouraged residents to report such activities to designated Resident Engineers across all LGAs and LCDAs.
Permanent Secretary of the Lagos State Emergency Management Agency (LASEMA), Dr. Femi Oke-Osanyintolu, reaffirmed the state’s readiness: “We’ve activated local emergency committees in all LGAs to build community resilience and ensure rapid response.”
“Residents of low-lying wetland areas of the state were alerted to relocate upland in order to avoid needless loss of lives and property.”
