The Kenya Meteorological Department has issued a heavy rainfall advisory warning of sustained downpours across several parts of the country from March 3 to March 9, 2026.
In a statement released on Monday, the weatherman said rainfall amounts exceeding 20mm within 24 hours are expected in multiple regions, with the intensity projected to increase between March 4 and March 7 before gradually reducing in most areas by March 8.
According to Kenya Met, the anticipated rainfall is classified as moderate to heavy, with a probability of occurrence ranging between 33 and 66 percent.
“The rainfall is likely to intensify and peak between March 4 and 7, 2026, before decreasing in most areas by March 8, 2026,” the department stated.
However, even as showers reduce in several regions, heavy rainfall exceeding 20mm in 24 hours is expected to persist in the Lake Victoria Basin, Western Kenya, parts of the Central Highlands, the Southeastern lowlands, and the Coastal region until March 9.
Counties listed as areas of concern include Turkana, Samburu, Migori, Nyamira, Bungoma, Busia, Kakamega, Vihiga, West Pokot, Baringo, Elgeyo Marakwet, Trans Nzoia, Nandi, Uasin Gishu, Nakuru, Siaya, Kisumu, Homa Bay, Kisii, Kericho, Bomet, Kiambu, Embu, Murang’a, Kirinyaga, Nyandarua, Nyeri, Laikipia, Tharaka-Nithi, Meru, Nairobi, Narok, Kajiado, Makueni, Machakos, Taita-Taveta, Kitui, Kwale, Mombasa, Tana River, Kilifi, Isiolo, Marsabit, Garissa, and parts of Wajir and Mandera.
Residents in the affected counties have been urged to remain vigilant due to the risk of floods, flash floods, and reduced visibility. The department cautioned that floodwaters may occur even in areas that do not experience heavy rainfall directly, particularly in downstream locations.
“People are advised to avoid driving through or walking in moving water or open fields and not to shelter under trees and near grilled windows to minimise exposure to lightning strikes. Updates will be provided promptly if there are any changes,” Kenya Met warned.
The department further noted that the long rains season has begun earlier than usual in several parts of the country. Farmers have been encouraged to begin planting activities to take advantage of the favourable weather conditions.
Kenyans are advised to continue monitoring official weather updates as the situation evolves.
