The heavy rains and torrential downpour that struck Nairobi on March 6, 2026, have caused widespread flooding, turning major roads into rivers and severely disrupting the city. Key affected routes included Mombasa Road (A8), where flash floods paralyzed traffic, submerged vehicles, and created massive delays.
Other routes affected included Thika Road (including sections like Githurai, Kahawa Sukari, and Pangani Interchange); parts of the Central Business District (CBD), such as Kenyatta Avenue, Kirinyaga Road, Uhuru Highway, Uhuru Park areas, and nearby streets.
Vehicles were submerged or swept away in some spots, such as Nairobi West and along swollen rivers like the Nairobi River, leading to stranded commuters, traffic chaos, property damage, and power disruptions in certain areas. In response to the flooding on Mombasa Road, the Nairobi Expressway (operated by MOJA Expressway) opened for free use from 9 p.m. to 11 p.m. on March 6, later extended until 6 a.m. on March 7, to provide an alternative route and ease congestion.
Public frustration has mounted, with many residents and social media users criticizing Nairobi Governor Johnson Sakaja for the city’s persistent flooding issues. Complaints highlight outdated and clogged drainage systems, encroachments on riparian lands, garbage buildup blocking drains, and repeated floods since at least 2015—even in upscale areas—despite prior promises and revenue collected for infrastructure.
Governor Sakaja responded by stating that Nairobi City County has fully mobilized resources and personnel through its Disaster Management and Risk Department. Measures included deploying teams to clear blockages and drains, activating the disaster committee for coordination, urging residents to stay vigilant, avoid flooded areas, prioritize safety, and use emergency hotlines (e.g., 020 2222181 / 020 2223182), and highlighting ongoing longer-term projects, such as a new 60-km trunk sewer to improve drainage.
He emphasized cooperation with emergency teams and evacuation to safer areas if needed. Critics, including political figures like Moses Kuria, have called for more decisive action and modern drainage solutions, pointing to systemic issues beyond the current administration.
The Kenya Meteorological Department had forecasted heavy rainfall from March 4–9, with peak intensity around this period, and warnings of flash flood risks continue. Residents are advised to exercise caution, avoid swollen rivers, and report emergencies promptly.
