Flood Alert: Why Imo, South-East Must Prepare for Rising Waters

Residents of Imo State and other parts of South-East states have been placed on alert following a flood forecast by the Nigeria Hydrological Services Agency (NIHSA), warning of a medium flood risk between July 21 and July 27, 2026.

According to NIHSA's National Flood Advisory, Imo is among the states expected to experience localized flooding as river levels continue to rise beyond warning thresholds. The agency says the situation could significantly disrupt communities, public services, agriculture, and transportation if precautionary measures are not taken.

Imo State appears to be one of the most vulnerable states in the South-East based on the agency's exposure assessment. NIHSA estimates that flooding could affect 415 communities, 423 schools, 198 health facilities, 49 markets, 111 religious centres, and about 75 hectares of farmland. Such widespread exposure raises concerns about disruptions to education, healthcare delivery, local commerce, food production, and livelihoods.

Although NIHSA did not identify the remaining 11 states in its summary, the warning underscores the likelihood that other South-East states could also experience localized flooding, particularly communities situated along rivers, streams, and low-lying floodplains. Heavy rainfall across the region could worsen existing drainage challenges in urban centres and increase the risk of flash floods.

Flooding in the South-East often results in the destruction of roads and bridges, displacement of families, damage to homes and businesses, and contamination of water sources, increasing the risk of waterborne diseases. Farmers may also suffer crop losses at a critical stage of the planting season, potentially affecting food supply and household incomes.

NIHSA attributed the heightened flood risk to rising water levels recorded at several monitoring stations across the country, with 16 hydrological gauging stations already exceeding watch and warning thresholds. The agency warned that communities along major river channels face the greatest danger of localized inundation.

To reduce the impact, NIHSA urged residents in flood-prone areas to relocate to safer locations where necessary, while emergency management agencies are advised to pre-position relief materials, activate community early-warning systems, and ensure drainage channels remain free of blockages.

The agency also cautioned the public against attempting to walk, drive, or ride through flooded roads and advised state governments and residents to monitor daily flood updates throughout the forecast period.

For communities across Imo and the wider South-East, the advisory serves as a reminder to prepare early and take preventive measures to minimize the potential loss of lives, property, and livelihoods.
