Kenya is bracing for heavy rainfall this weekend, with the Kenya Meteorological Department warning of possible flooding and travel disruptions.

The alert, issued on Thursday, covers the period between Friday, 3 October, and Sunday, 5 October 2025. It warns of “isolated heavy rainfall of 20mm to 50mm in 24 hours, and in some places very heavy rainfall exceeding 50mm in 24 hours.”

Regions likely to be most affected include the central highlands, Nairobi, the Lake Victoria basin, the Rift Valley, and parts of western and north-western Kenya.

“This could lead to localised flooding, slippery roads, and possible disruptions,” the department noted.

Public Caution

Residents and travellers have been urged to stay alert, especially in low-lying and flood-prone areas. Motorists are advised to drive carefully due to reduced visibility and slippery surfaces, while pedestrians are warned against crossing flooded areas and open drains.

October marks the beginning of Kenya’s short rains, which run through December. While vital for agriculture and water supply, these rains often bring risks in both urban and rural areas.

In Nairobi and other cities, poor drainage frequently results in flash floods. In rural regions, unpaved roads may become impassable, affecting access to schools, markets, and hospitals.

Wider Impact

The Coastal region may also see rainfall, with possible impacts on ferry services, urban drainage, and settlements in Mombasa, Kilifi, and Lamu. Meanwhile, most of north-eastern Kenya and parts of the south-east—including Garissa, Wajir, Mandera, Kitui, and Tana River—are expected to remain dry, raising water resource concerns there.

The Kenya Red Cross has emphasised that early preparedness can greatly reduce the risks. County governments and disaster response teams have been urged to remain on high alert to minimise harm to communities.

Looking Ahead

Previous weather events have led to transport disruptions, power cuts, and displacement of residents. With the official start of the short rains season now underway, the Meteorological Department says it will continue to monitor patterns and provide regular updates.
