Heavy rains that pounded Nairobi overnight have led to flash floods that claimed the lives of at least six individuals, authorities reported on Tuesday.

Police warned that the death toll could climb, as several people are still unaccounted for and may have been swept downstream.

Among the fatalities were a mother and her two children, who lost their lives when a large rock rolled down and destroyed their home in Mathare’s 4A area.

Nairobi Police Commander George Sedah stated that the rock collapsed after intense rainfall caused a nearby river to overflow, weakening the hillside. The family drowned after the rock crushed their house while they were asleep.

In another tragic incident, one person died in the Mukuru Kwa Reuben slum after being carried away by floodwaters.

Police noted that more than 500 residents in the area were displaced as their homes flooded during the night.

Two other bodies were retrieved from different parts of the city. One was found in the Ngong River near Likoni Bridge in South B, and the second along Jogoo Road, both believed to have drowned due to the floods.

Local authorities have begun evacuating residents from high-risk areas, particularly where unstable terrain or rising water levels pose further threats.

Rescue operations are underway, and emergency teams are combing affected neighborhoods for survivors and additional victims.

Residents in Mukuru have expressed frustration, saying they’ve been repeatedly overlooked despite ongoing promises from officials, especially after past flood disasters.

The Nairobi County Government announced that response teams are on the ground addressing the emergency. Efforts include clearing blocked drainage systems to prevent further flooding.

The Kenya Meteorological Department has forecast continued rainfall and thunderstorms throughout the week, raising concerns about more potential flooding across the capital and other regions.
