The Kenya Meteorological Department has issued a five-day weather alert warning of sustained rainfall, chilly nights, and varying daytime temperatures across multiple parts of the country.
In its latest forecast covering April 17 to April 22, the agency said several regions—including Central Kenya, the Rift Valley, the Lake Victoria basin, southeastern lowlands, and the Coast—should prepare for continued showers, with some areas likely to experience heavy downpours and thunderstorms.
Western Kenya, Rift Valley to receive heavy rains
Counties in western Kenya and the Rift Valley are expected to bear the brunt of the rainfall. Areas such as Siaya, Kisumu, Homa Bay, Migori, Kisii, Nyamira, Trans Nzoia, Uasin Gishu, Nakuru, Narok, Kericho, Bomet, Kakamega, Bungoma, and Busia are likely to experience intense afternoon and nighttime storms.
The department warned that most storms will develop later in the day and persist into the night, increasing the risk of flooding and reduced visibility.
“Morning rains may occur in a few areas, followed by afternoon showers and thunderstorms that could spread widely. Night showers are also expected in some regions,” the agency said.
Moderate rainfall expected in Central and Coastal regions
In Central Kenya—including Nyeri, Kiambu, Murang’a, Kirinyaga, Nyandarua, Meru, Embu, and Nairobi—residents should expect intermittent rainfall patterns, with cloudy mornings, sunny breaks, and occasional afternoon showers.
Similar conditions are forecast for coastal counties such as Mombasa, Kilifi, Lamu, and Kwale, as well as southeastern areas including Kitui, Machakos, Makueni, Kajiado, and Taita Taveta.
Cold nights, warm days to persist
Beyond rainfall, the weather agency warned of significantly cold nights in Central Kenya, where temperatures could drop to around 10°C.
At the same time, daytime temperatures are expected to remain relatively high in western and coastal regions, reaching up to 31°C.
This contrast between cold nights and warm days is likely to create unstable weather conditions that could impact both health and agricultural activities.
Call for preparedness as long rains continue
The advisory comes during Kenya’s long rain season, which typically runs from March to May and is often associated with flooding, transport disruptions, and displacement in vulnerable areas.
Authorities have previously urged counties to strengthen disaster preparedness measures in line with national policies under the Constitution of Kenya 2010, which mandates the protection of life and property.
Kenyans living in flood-prone areas are being advised to remain alert, while farmers are encouraged to align their planting schedules with the forecast to minimise losses.
