Parts of Port Harcourt, the capital of Rivers State, were submerged by flash floods in late September 2026. The sudden deluge overwhelmed drainage systems, causing streets to flood and homes to be partially submerged. Local authorities suspended other assembly matters to address the crisis.

The floods, described as flash floods, hit the area late on a Saturday, September 25, 2026. Heavy rainfall, exceeding 150 millimeters in 24 hours, led to rapid water accumulation. Residents reported that water levels reached up to their ankles in some areas, forcing them to evacuate their homes.

This event follows a series of extreme weather events in the region. In 2025, Rivers State experienced similar flooding that displaced over 10,000 people. Climate experts warn that rising temperatures and erratic rainfall patterns are increasing the frequency of such disasters. The government has pledged to improve infrastructure but has yet to implement long-term solutions.
