The Kenya Meteorological Service has forecast rainfall in 24 counties this week as the October-December short rains season gathers momentum across the country.
In an update issued on Thursday, the department said showers are expected in parts of West Pokot, Siaya, Elgeyo Marakwet, Bungoma, Kakamega, Nakuru, Trans Nzoia, Kericho, Kisii, Homa Bay, Kisumu, Mandera, Wajir, Marsabit, Nyandarua, Meru, Nyeri, Embu, Kirinyaga, Tharaka Nithi, Kwale, Mombasa, Kilifi and Lamu.
The forecast also warned of strong southerly to southeasterly winds exceeding 25 knots, equivalent to 12.5 metres per second, in parts of Turkana, Samburu and Marsabit counties.
The latest outlook follows the onset of the October-December rainfall season, which the weather agency expects to bring varying amounts of rain across the country.
According to the department, rainfall patterns during the season will be influenced by several climate drivers, including the Indian Ocean Dipole (IOD), the El Niño-Southern Oscillation (ENSO) and other atmospheric systems.
Earlier forecasts indicated that rainfall had begun in parts of 24 counties by October 5, with more areas expected to experience showers in the weeks ahead.
The anticipated rains are expected to provide relief to farmers by improving soil moisture, supporting planting activities and promoting pasture regeneration. Increased water availability could also benefit livestock keepers, particularly in arid and semi-arid areas.
However, the agency has cautioned that above-normal rainfall could bring challenges, including flooding, waterlogging, crop diseases and disruptions to farming activities and transport.
Parts of the Coast and northeastern regions have been highlighted as areas that could experience heavy rainfall during the season. Residents in flood-prone areas, particularly those living near rivers and in low-lying locations, have been urged to remain alert and take appropriate precautions.
The World Meteorological Organization has also projected wetter-than-normal conditions across the Greater Horn of Africa during the final quarter of 2026 as El Niño strengthens.
The October-December period is particularly important for Kenya and other countries in the region because it contributes significantly to annual rainfall in several areas.
Residents have been encouraged to follow official weather updates as conditions evolve throughout the season.
