The Nigerian Meteorological Agency has warned that 13 states could experience flash floods between August 11 and 20, 2026.
NiMet issued the warning in an advisory shared on its X handle on Tuesday, identifying Sokoto, Zamfara, Kebbi, Niger, Kaduna, Nasarawa, Adamawa, Plateau, Benue, Kogi, Taraba, Cross River and Akwa Ibom as states at high risk.
The agency said its assessment was based on several factors, including projected rainfall intensity, existing soil moisture levels, drainage capacity, terrain and dam characteristics.
“It serves as an early warning and decision-support tool for proactive preparedness, emergency response planning, and disaster risk-reduction measures.
“States with High Flash Flood Risk: Sokoto, Zamfara, Kebbi, Niger, Kaduna, Nasarawa, Adamawa, Plateau, Benue, Kogi, Taraba, Cross River, Akwa Ibom,” the advisory read.
According to the agency, the risk is particularly high in flood-prone, low-lying, urban and riverside communities, where intense rainfall could trigger localised flash flooding.
NiMet warned that flooding could lead to road closures, traffic congestion and disruptions to transportation, while electricity and telecommunications services could also face temporary interruptions.
The agency further noted that heavy rainfall could impair visibility and disrupt motorists and aviation operations.
It added that waterlogging could negatively affect farms, crops and livestock.
NiMet also cautioned that floodwaters could damage roads, bridges, drainage networks and other critical infrastructure, while stagnant water could heighten the risk of waterborne diseases.
Residents were advised to monitor NiMet’s weather forecasts and flood alerts from relevant emergency management authorities.
The agency urged members of the public to avoid walking or driving through flooded roads, bridges and fast-moving water.
Those living in vulnerable locations were advised to remain vigilant and be prepared to relocate to safer areas when necessary.
NiMet also called on emergency management agencies to intensify surveillance, position response teams in advance and maintain a high level of emergency preparedness.
Farmers were advised to improve drainage on their farms and relocate livestock, machinery and harvested produce from areas prone to flooding.
The agency further urged authorities to give priority to vulnerable communities through impact-based monitoring, public awareness campaigns and rapid communication of flood warnings.
“Preparedness should be maintained even in areas with lower flood probability, as flash flooding can develop rapidly during intense rainfall,” NiMet said.
