The Nigeria Hydrological Services Agency (NIHSA) has issued a fresh flood alert, warning that 28 states and the Federal Capital Territory (FCT) face a high risk of flooding between Tuesday and August 5.
In a statement on Monday, NIHSA’s Director General, Mr. Umar Mohammad, said over 739 communities and 162 Local Government Areas are expected to be affected during this period.
The warning, he explained, is consistent with the agency’s 2025 Annual Flood Outlook (AFO) released on April 10.
States on the red alert list include Adamawa, Akwa Ibom, Anambra, Bauchi, Bayelsa, Benue, Borno, Cross River, Delta, Ebonyi, Edo, FCT, Gombe, Imo, Jigawa, Kebbi, Kogi, Kwara, Lagos, Nasarawa, Niger, Ondo, Plateau, Rivers, Sokoto, Taraba, and Yobe.
NIHSA also warned that flooding could disrupt more than 100 major transportation routes, including critical economic corridors such as the Okene-Lokoja-Abuja Road, Birnin Kebbi-Bunza Road, Ibi-Wukari Road, and several key routes in Lagos, FCT, and the Niger Delta.
“There is an increased risk of property damage to homes, businesses, and critical infrastructure, particularly in low-lying and flood-prone areas,” the statement read. “In addition, agricultural lands are under serious threat, which could impact food security in several regions.”
The agency urged emergency management stakeholders to activate their preparedness and response mechanisms, adding that at-risk communities should not delay in implementing evacuation plans.
NIHSA further advised Nigerians to monitor its weekly updates and forecasts through its Flood Dashboard at www.nihsa.gov.ng and other official social media platforms.
