Weatherman Warns of Heavy Rains, Flood Risks in 20 Counties

Rainfall to be expected in 20 counties

The Kenya Meteorological Department has released a yellow warning advisory, predicting heavy rainfall and strong winds across several parts of the country from September 17 to 19.

The advisory warns that rainfall will intensify to more than 20mm in 24 hours over the Lake Victoria Basin, Rift Valley and the Highlands west of the Rift, before spreading to the Highlands east of the Rift on September 17.

The heavy downpour is expected to persist until September 19, before easing from September 20.

“Residents in the Highlands should expect occasional morning showers followed by afternoon thunderstorms in several counties,” Kenya Met stated.

“Night showers are likely in some areas, so farmers and commuters should take necessary precautions.”

The department cautioned that the heavy rains could trigger flash floods, lightning, and poor visibility, with a special warning for those living near rivers and seasonal streams.

“People living downstream rivers and along seasonal rivers should be careful since water may appear suddenly even though it may not be raining within the area,” the advisory read.

Strong southerly winds exceeding 25 knots (12.8 m/s) are also projected, particularly in the eastern sector, with risks of damage to property.

The weatherman noted that the winds might blow off roofs, uproot trees and cause structural damage, while also disrupting transport and marine activities.

Counties likely to be affected include Kisumu, Homa Bay, Siaya, Migori, Busia, Kakamega, Bungoma, Kericho, Bomet, Nyamira, Kisii, Nakuru, Nandi, Baringo, Narok, Trans-Nzoia, Uasin Gishu, Elgeyo-Marakwet, West Pokot, Turkana, Samburu, Marsabit, Nyandarua, Laikipia, Nyeri, Kirinyaga, Nairobi and parts of Murang’a, Kiambu, Meru, Embu and Tharaka-Nithi.

“Residents 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 minimize exposure to lightning strikes,” the department urged.

Kenya Met emphasized that while the rains are of moderate certainty, preparedness was crucial to minimize risks.
