The Kenya Meteorological Department (KMD) has issued a renewed weather advisory warning that rainfall will intensify across several parts of the country beginning Wednesday, raising the risk of flooding, strong winds, and other hazardous conditions in both inland and coastal regions.
In its statement released on Tuesday, April 21, 2026, the department noted that while many areas are already experiencing rainfall, the intensity is expected to increase significantly between April 22 and April 27. KMD further warned that flooding could also occur in areas that may not directly receive heavy rain due to runoff from neighbouring high rainfall regions.
The Lake Victoria Basin and Western Kenya are expected to be among the hardest hit. Counties including Kisumu, Siaya, Homa Bay, Migori, Kakamega, Vihiga, Bungoma, Busia, Kisii, and Nyamira are likely to experience continued thunderstorms and prolonged showers. Residents in these areas have been advised to stay alert as conditions may worsen.
In the Rift Valley region, increased rainfall is forecast for Nakuru, Narok, Kericho, Bomet, Uasin Gishu, Elgeyo Marakwet, Nandi, Baringo, West Pokot, Trans Nzoia, and Samburu counties. The met department cautioned that already saturated ground could lead to flash floods and possible landslides, especially in elevated and hilly terrain.
The Highlands East of the Rift Valley, including Nairobi, Nyandarua, Nyeri, Kiambu, Murang’a, Kirinyaga, Laikipia, Embu, Meru, and Tharaka Nithi, will continue to experience persistent rainfall with occasional thunderstorms. Urban flooding remains a key concern, particularly in densely populated towns and cities.
In the South-Eastern Lowlands and Coastal strip, Machakos, Kitui, Makueni, Kajiado, Taita Taveta, Tana River, Mombasa, Kilifi, Lamu, and Kwale are expected to receive irregular but sometimes heavy showers. Strong winds and rough sea conditions are also likely to disrupt marine and coastal activities.
KMD has urged the public across all affected regions to exercise caution, avoid walking or driving through flooded roads, and remain alert to updates, warning that even short periods of rainfall could quickly escalate into dangerous flooding situations.
