NiMet Alerts 13 States to Flash Flood Risk Through August 20

The Nigerian Meteorological Agency has flagged a risk of flash flooding in 13 states over a ten-day window running from August 11 to 20, 2026. The warning was posted Tuesday on NiMet's official X account, naming the states considered most vulnerable: Sokoto, Zamfara, Kebbi, Niger, Kaduna, Nasarawa, Adamawa, Plateau, Benue, Kogi, Taraba, Cross River and Akwa Ibom. According to the agency, the assessment draws on several factors, including expected rainfall intensity, current soil moisture levels, how well local drainage systems can cope, terrain features and dam conditions in the affected regions. NiMet described the advisory as a tool meant to support early preparedness, helping emergency planners and disaster-response teams act ahead of potential flooding rather than after it strikes. Communities situated in low-lying, flood-prone, urban or riverside areas face the greatest exposure, the agency said, warning that localised flash floods could disrupt daily life in multiple ways. Possible effects include snarled traffic, blocked roads and broader transport disruptions, along with brief outages in power and telecom services. Heavy downpours could also cut down visibility on the roads and in the air, creating hazards for both drivers and aircraft operators. Farmers were flagged as particularly at risk, with waterlogging threatening crops, farmland and livestock. Beyond the immediate disruption, NiMet cautioned that flash floods could inflict lasting damage on infrastructure, including roads, bridges and drainage networks, while water that pools and stagnates afterward could become a breeding ground for waterborne illness. To limit the fallout, the agency is asking residents to stay informed by tracking forecasts and advisories from NiMet and other emergency bodies, and to steer clear of flooded roads, bridges or any fast-moving water. People living in high-risk zones were told to stay alert and be ready to relocate to safer ground if conditions worsen. NiMet also directed a set of recommendations at emergency management agencies, calling for tighter surveillance, response teams positioned in advance, and sustained readiness throughout the warning period. Farmers, meanwhile, were encouraged to shore up drainage on their land and shift livestock, equipment and stored produce out of areas likely to flood. The agency further urged authorities to focus monitoring and public awareness efforts on the most vulnerable communities, ensuring warnings reach residents quickly. It closed with a reminder that even regions considered lower-risk should not let their guard down, since flash floods can form rapidly once heavy rain sets in.
