Weather Alert- Kenya Met Warns Of Heavy Rainfall And Chilly Nights This Weekend

The Kenya Meteorological Service Authority has issued a weather advisory urging citizens to prepare for significant rainfall starting Friday, May 8, through Tuesday, May 12, 2026. According to the forecast, heavy rains are expected to impact several regions, including Western Kenya, the Rift Valley, the Lake Victoria Basin, and Central Kenya.

In the Western and Rift Valley regions, counties such as Siaya, Kisumu, Homa Bay, Migori, Kisii, and Nyamira, alongside Trans Nzoia, Baringo, Uasin Gishu, and Nakuru, are likely to experience downpours. The weatherman notes that while these areas may see slight mid-morning showers, more intense rainfall is expected to develop in the afternoons following cloudy conditions.

Thunderstorms and Potential Flooding

Central Kenya, including Nairobi, Kiambu, Murang’a, Nyeri, and Meru, is also on high alert. The meteorological department warned that rainfall in these areas would be accompanied by thunderstorms, and residents have been urged to stay vigilant against potential flash floods. Meanwhile, the coastal strip, covering Mombasa, Kilifi, Lamu, and Kwale, is projected to receive moderate rainfall over the same period.

In contrast, the Southeastern lowlands, including Machakos, Kitui, and Makueni, are expected to remain largely dry and cloudy. Northern Kenya and the Coast are also forecast to experience high daytime temperatures, with some areas reaching peaks of up to 37°C.

Brace for Cold Nights

Beyond the rainfall, residents of Central Kenya and the highlands should prepare for a significant drop in temperatures. Nighttime temperatures in counties like Nyandarua, Laikipia, and Nairobi are expected to plunge as low as 9°C.

The authority advises those in the affected regions to carry umbrellas, dress warmly for the cold nights, and avoid crossing flooded roads or sheltering under trees during thunderstorms.
