Flash floods are often triggered by intense rainfall or the sudden release of water from reservoirs or dams and pose a serious threat to communities in Nigeria, particularly urban areas grappling with poor drainage systems, deforestation, and rapid construction.
These floods are characterized by a sudden surge of water, often overwhelming homes, streets, and vehicles.
Climate change has heightened the threats of flash floods, and Nigeria has experienced shifts in weather patterns, rendering it vulnerable to intense rainfall and consequent flash floods.
According to the Director-General/CEO of the Nigeria Hydrological Services Agency (NIHSA), Clement Nze, the Cameroonian Lagdo dam commenced water release on August 14, 2023, at a rate of 200 cubic meters per second.
Nze explained that although the rate has been reduced to 50 cubic meters per second, the agency remains on high alert as the rainy season persists.
“Due to the rise in the water levels of River Benue and River Niger, communities along River Benue and River Niger up to Bayelsa state should take precautionary measures,” an advisory issued by the Federal Ministry of Environment through the National Flood Early Warning Systems (FEWS) Central Hub said.
With at least 15 out of the country’s 36 states predicted to experience torrential rain, here are proactive steps to take and five ways to prioritise your safety if you find yourself stuck in a flash flood:
- Stay Informed: Before venturing out, always check weather forecasts, warnings, and alerts. Pay attention to any flash flood warnings issued by local authorities.
- Avoid Walking or Driving Through Floodwaters: Do not attempt to walk or drive through floodwaters, no matter how shallow they may appear. Also, avoid entering buildings that are flooded or surrounded by floodwaters, as the structure may be compromised, posing a risk of collapse.
- Find Shelter on High Ground: Seek shelter in a sturdy building on higher ground and if you cannot find a building, climb to a higher place such as a tree, roof, or hill. Stay where you are once you find a safe location and do not attempt to venture out until the floodwaters have receded. You can signal for help by using a flashlight, waving a cloth, or making noise.
- Turn Off Utilities: If at home, turn off electricity and gas at the main switches or valves to prevent accidents during a flood.
- Stay Informed About Rescue Operations: Listen to emergency broadcasts or updates to know when it is safe to evacuate or when rescue operations are underway.
