The Kenya Meteorological Department has warned of fresh flooding in Nairobi metropolitan areas, urging residents to remain alert due to the high risk of flash flooding.
The advisory issued on Saturday, March 7, which is active until March 9 at 7pm, indicates that moderate to heavy showers are likely to persist across Nairobi, Kiambu, and Kajiado as soils remain saturated following recent downpours.
The weatherman warned that even moderate rainfall could trigger flash floods and surface runoff due to the already waterlogged ground conditions across urban centres.
In Nairobi County, widespread moderate to heavy rainfall is expected, with accumulations ranging between 20mm and 60mm in most areas, while isolated intense pockets could receive between 80mm and 10mm.
Areas identified as high-risk zones include Kibra, Dagoretti North and South, Embakasi, Makadara, Kamukunji, Roysambu, Westlands, Langata, and parts of Mathare, where poor drainage systems may worsen flooding risks.
Neighbouring Kajiado County is also expected to experience scattered to widespread heavy rainfall, with hotspots of between 40 mm and 100 mm, particularly in Kajiado North, West, and Central sub-counties.
In Kiambu County, the met department projected rainfall accumulations of more than 80 mm in some areas, including Thika, Juja, Ruiru, Limuru, Kikuyu, Githunguri, and Kabete, raising concerns over possible mudslides on steep slopes.
Residents of Machakos County were also warned of isolated heavy rainfall of up to 80 mm, particularly in Masinga, Mavoko, Kathiani, Machakos Town, Matungulu, Yatta, and Kangundo, where flash flooding in river catchments is likely.
At the same time, the government has urged the public to avoid driving through flooded roads, stay away from steep slopes during heavy rains, and ensure drinking water is properly treated by boiling or other safe methods.
