The Kenya Meteorological Department has warned of possible flash floods in parts of the country as rainfall is expected in 46 counties over the next week.

In its weather forecast for October 22 to 29, 2026, the department said several parts of the country, including Nairobi and Marsabit, are likely to receive rainfall.

The counties expected to experience rainfall include Mandera, Wajir, Garissa, Tana River, Lamu, Kilifi, Mombasa, Kwale, Meru, Embu, Baringo, Bomet, Bungoma, Busia, Elgeyo Marakwet, Homa Bay, Kajiado, Kakamega, Kericho, Kiambu, Kirinyaga, Kisii, Kisumu, Kitui, Laikipia, Machakos, Makueni, Migori, Murang’a, Nakuru, Nandi, Narok, Nyamira, Nyandarua, Nyeri, Siaya, Taita Taveta, Tharaka-Nithi, Trans Nzoia, Turkana, Uasin Gishu, Vihiga and West Pokot.

The department singled out parts of Mandera, Wajir, Lamu, Kilifi, Mombasa and Kwale as areas that could experience isolated storms capable of triggering flash floods.

It noted that rainfall may not be evenly distributed, meaning some areas within the affected counties could receive heavier rainfall than others.

Residents in flood-prone areas, especially those living near rivers and other waterways, have been urged to remain alert and exercise caution.

Motorists and pedestrians have also been advised to avoid flooded roads, rivers, bridges and other waterways. The department warned against attempting to cross flooded areas, whether on foot or by vehicle.

During thunderstorms, residents should avoid sheltering under trees or standing near isolated tall structures due to the risk of lightning strikes.

Motorists have been urged to slow down, keep a safe distance from other vehicles and use headlights when visibility is poor.

Those living on or below steep slopes and unstable hillsides have also been advised to watch out for signs of possible landslides, including cracks in the ground, leaning trees, unusual ground movement and sudden changes in water flow.
