The Kenya Meteorological Department has forecast rainfall in 44 counties between September 15 and 21, 2026, as the El Niño weather phenomenon continues to influence weather patterns across the country.

The department said sunny intervals are expected in the afternoons in most parts of Isiolo, Mandera, Marsabit, Samburu, Turkana and Wajir counties.
The forecast comes after most parts of the country remained dry between September 7 and 13, with rainfall recorded in only a few counties, notably Busia, Kisii, Kilifi, Mombasa and Kwale.
Busia recorded the highest seven-day rainfall total at 120.7 millimetres at the Ministry of Water rainfall station.

The department has advised the public to use the seven-day forecast together with its daily and five-day weather forecasts, while county-specific forecasts are available through County Directors of Meteorological Services.
"As we prepare for the OND season, the window for preparedness is now. Use weather information to plan ahead, protect lives and livelihoods, and take action before hazards occur," it said.
