The Kenya Meteorological Department has advised residents across several parts of the country to prepare for moderate to heavy rainfall over the next five days, following its weekend weather advisory released on Friday, March 13, 2026.

According to Kenya Met, the rains are expected to affect five broad regions; Western Kenya, the Central Highlands, the Lake Victoria Basin, the Rift Valley, and the South-eastern lowlands.

Counties in Western Kenya, the Rift Valley, and the Lake Victoria Basin falling under the forecast include Siaya, Kisumu, Homa Bay, Migori, Kisii, Nyamira, Trans Nzoia, Baringo, Uasin Gishu, Elgeyo Marakwet, Nandi, Nakuru, Narok, Kericho, Bomet, Kakamega, Vihiga, Bungoma, Busia, and West Pokot.

These areas are expected to receive heavy afternoon downpours accompanied by thunderstorms, preceded by light morning showers and sunny mid-morning intervals.

Night rains are also anticipated in some of these counties.

A similar weather pattern is forecast for the Central Highland counties of Nyandarua, Laikipia, Nyeri, Kirinyaga, Murang’a, Kiambu, Meru, Embu, Tharaka Nithi, and Nairobi.

Residents in these areas should expect heavy rains from Friday through Saturday, after which rainfall is projected to ease for the remainder of the forecast period.
