The Kenya Meteorological Department (KMD) has issued an urgent advisory warning of continued heavy rainfall across the Nairobi Metropolitan region, keeping flood risks at critical levels for the next 48 hours.

The skies over Nairobi have turned into a relentless faucet. Since late February, the capital has been subjected to a consistent, punishing wet spell that has pushed local infrastructure to its breaking point. As of March 8, 2026, the Kenya Meteorological Department has confirmed that while the peak intensity observed between March 4 and March 7 has eased slightly, the danger is far from over.

For the residents of Nairobi, the "so what?" is immediate and visceral. The ground in the city is already saturated, meaning that even moderate showers now carry the threat of flash flooding. The city’s drainage systems, already overwhelmed by the record-breaking 160mm of rainfall recorded at Wilson Airport earlier this week, cannot handle further volume. This creates a high risk of localized flooding in low-lying residential and commercial zones, disrupting transport, sanitation, and commerce.

The Geography of Risk

The KMD has specifically identified vulnerable zones that require extreme vigilance. The advisory, which remains in force until at least March 9, highlights the following areas as being at high risk for intensified rainfall:

• Southern Nairobi: Embakasi and its surrounding sub-counties.
• High-Density Settlements: Kibra, Makadara, and Kamukunji.
• Northern & Western Corridors: Parts of Roysambu, Westlands, and Kasarani.

These regions are susceptible not only to surface water flooding but also to infrastructural damage. Motorists are urged to avoid known hotspots where roads frequently become impassable. The saturation levels mean that slopes, particularly in the western fringes of the city, could be prone to mudslides, compounding the risks to informal settlements built in precarious topography.

Public Health and Long-term Preparedness

Beyond the immediate threat to mobility, the Ministry of Health has signaled an alert regarding water-borne and vector-borne diseases. Stagnant water, a byproduct of these floods, serves as a breeding ground for mosquitoes and elevates the risk of cholera and typhoid. The public is advised to boil drinking water and avoid wading through floodwaters, which may be contaminated by sewage overflow.

The persistence of these rains points to a broader challenge: Nairobi’s urban planning. With rainfall patterns shifting, the historical drainage capacity designed for the city’s past climate is no longer sufficient. Forward-looking strategies will need to incorporate deep-tunnel drainage and significant upgrades to waste management infrastructure to prevent the annual economic paralysis that accompanies the long rains.

As the weather office continues to monitor the situation, the Kicker remains: This is a test of resilience. While the rains may abate, the city must now brace for the recovery phase, focusing on sanitation and the restoration of damaged public utilities.
