Nairobi Metropolitan area Residents Warned of Heavy Rainfall

A heavy rainfall advisory for the Nairobi Metropolitan region, has been issued warning residents to remain vigilant as showers and isolated thunderstorms continue across the area. The Kenya Meteorological Department (KMD) said the advisory is in effect until 7 pm on Monday, 9 March 2026. Met noted that although the intensity of the rains has slightly eased compared to the peak period between March 4-7, moderate to heavy rainfall will persist, with the potential to cause localised flooding. The department noted that soils in the region remain saturated due to prolonged wet spells since late February. “The expected rains are likely to still cause flooding as the soils are saturated from prolonged wet spells since towards the end of February,” the department said in a statement. In Nairobi County, widespread showers are forecast today and tomorrow, with isolated heavier pockets expected in southern areas including Embakasi, Kibra, Makadara, Kamukunji, as well as parts of Roysambu, Westlands, Dagoretti, and Kasarani. Residents in these neighborhoods have been advised to take precautionary measures, especially in low-lying and flood-prone areas. Neighbouring Kiambu County will also experience showers across Gatundu, Thika, Juja, Ruiru, Limuru, Kikuyu, Kabete, and Githunguri, while parts of Kajiado County – specifically the north, west, and central regions – will see intermittent rainfall. In Machakos County, showers are expected in Kathiani, Machakos Town, Matungulu, Yatta, and the northern areas. The KMD urged motorists and commuters to drive cautiously on slippery roads and to avoid crossing flooded sections of rivers and roads.

Flood-prone areas, in particular, have been advised to take necessary precautions, including relocating valuables and avoiding unnecessary travel during periods of heavy rain. Meanwhile, Ministry of Health Kenya has issued a public health alert warning of a possible rise in water-borne and vector-borne diseases as heavy rains continue to pound several parts of the country. In a statement signed by Principal Secretary for Public Health and Professional Standards Mary Muthoni, the ministry cautioned that the ongoing March–April–May rains could increase the risk of disease outbreaks if preventive measures are not observed. The ministry noted that while the rains are crucial for agriculture and replenishing water resources, they also create conditions that may expose communities to various public health threats. “The Ministry of Health wishes to alert the public that the ongoing March-April-May long rains are expected to continue in several parts of the country,” the statement read. “While the rains are important for agriculture and water resources, they may also increase the risk of certain public health threats.” According to the ministry, heavy rainfall and flooding can contaminate water sources, disrupt sanitation systems and create ideal breeding grounds for disease-carrying vectors such as mosquitoes.
