Heavy Rains to Intensify Across Kenya as the Met Department Warns of Flooding

The Kenya Meteorological Department issued an updated heavy rainfall advisory on March 3 warning that downpours already affecting much of the country will intensify over the coming days.

Rainfall totals surpassing 20 millimetres in 24 hours have been recorded in several counties, and the pattern is expected to continue through March 9.

The department highlighted that the rains will likely strengthen and reach their peak between March 4 and March 7 before easing in most places by March 8. Heavy falls may linger longer in certain zones until March 9.

Regions facing the greatest concern include the Lake Victoria Basin and Western Kenya, parts of the Central Highlands, the Southeastern lowlands and the Coastal strip.

A long list of counties stands at elevated risk: Turkana, Samburu, Migori, Nyamira, Bungoma, Busia, Kakamega, Vihiga, West Pokot, Baringo, Elgeyo Marakwet, Trans Nzoia, Nandi, Uasin Gishu, Nakuru, Siaya, Kisumu, Homa Bay, Kisii, Kericho, Bomet, Kiambu, Embu, Murang’a, Kirinyaga, Nyandarua, Nyeri, Laikipia, Tharaka-Nithi, Meru, Nairobi, Narok, Kajiado, Makueni, Machakos, Taita-Taveta, Kitui, Kwale, Mombasa, Tana River, Kilifi, Isiolo, Marsabit, Garissa, and sections of Wajir and Mandera.

Flood waters could appear in areas that have not seen the heaviest local rain, particularly downstream along river courses. Flash floods and poor visibility form part of the expected hazards.

The advisory carries clear instructions for residents in the named areas. People should stay alert for flooding, flash floods and reduced visibility on roads.

It urges against driving or walking through moving water and open fields during storms. To reduce lightning risks, avoid standing under trees or near grilled windows.

The department promised to issue prompt updates should conditions change.

This latest warning arrives amid ongoing heavy rains that have already prompted similar cautions in recent weeks. The current forecast covers a broad swathe of the country, from western border regions to the Indian Ocean coastline.

Urban centres like Nairobi, Kisumu and Mombasa fall within the affected zones, alongside rural and arid counties in the north and east that sometimes see rapid runoff.

No specific rainfall totals beyond the 20mm threshold were detailed for the peak period, but the emphasis remains on widespread moderate to heavy precipitation and secondary impacts.
