NIHSA chief executive officer, Umar Mohammed, said the agency's monitoring network has detected elevated water levels at critical stations, including Saminara on the Karam River, Waya Dam Site on the Waya River, and Amber on the Amber River.

Mohammed said:

"With 16 gauging stations showing elevated stages, communities along the primary channels face imminent localised flooding. We strongly advise state governments, local authorities, and residents on floodplains to act immediately."

He added that the forecast points to a need for "proactive risk management, timely evacuation, and inter-agency coordination to protect lives, livelihoods, and critical infrastructure."

Flooding threat: Schools, farmlands at risk

The advisory detailed the scale of exposure across the named states. Bauchi faces the widest community impact, with 1,841 communities, 145 schools, 101 health facilities, and 8 markets at risk. Imo state has 415 communities, 423 schools, 198 health facilities, 49 markets, 111 religious centres, and 75 hectares of farmland in the danger zone.

Mohammed directed the National Emergency Management Agency (NEMA), State Emergency Management Agencies, local government councils, and community leaders to enforce safety measures without delay. Key directives include moving residents, livestock, and valuables away from floodplains to designated shelters, pre-positioning medical supplies, food, and water treatment materials in safe locations, and clearing drainage systems, culverts, and river mouths of blockages.

Furthermore, residents were warned not to attempt crossing flooded roads, bridges, or fast-flowing water on foot, by vehicle, or by motorcycle.

The agency advised state actors and the public to track daily updates through official NIHSA bulletins throughout the alert period, The Sun noted.

Why weather forecasts are important

Legit.ng reports that weather forecasts are important because they provide valuable guidance for planning, support economic activities, and help protect lives and property. They have become an essential part of daily life, influencing decisions about clothing, travel, and outdoor activities.

Beyond predicting atmospheric conditions, weather forecasts also anticipate changes on the Earth's surface caused by weather events, including snow and ice cover, storm surges, and flooding.

Systematic weather records are particularly valuable in agriculture and other weather-dependent industries. Farmers can better plan planting and harvesting seasons by using long-term weather forecasts, improving productivity and reducing the risk of weather-related losses.

The aviation sector also relies heavily on accurate weather information. Airlines use weather forecasts to plan flight schedules, determine safe routes, and minimise delays caused by adverse conditions.

Overall, accurate weather forecasting is essential for anticipating extreme weather events, reducing their impact on communities, and safeguarding economies.

6 of the 17 Nigerian states that may be affected by floods, according to NIHSA, are highlighted below:

  • Bauchi
  • Edo
  • Imo
  • Kaduna
  • Plateau
  • Benue
