According to the department, although rainfall intensity has slightly reduced compared to the peak period between March 4 and March 7, moderate to heavy rain is still expected and could lead to localized flooding.

KMD explained that the ground in many parts of the region remains saturated due to persistent rainfall experienced since late February.

“The expected rains may still cause flooding because the soils are already saturated following prolonged wet conditions since late February,” the department said in a statement.

In Nairobi County, widespread showers are expected today and tomorrow, with heavier rainfall likely in southern areas such as Embakasi, Kibra, Makadara and Kamukunji, as well as parts of Roysambu, Westlands, Dagoretti and Kasarani.

Residents in these areas have been advised to take precautionary measures, particularly those living in low-lying and flood-prone locations.

Neighbouring Kiambu County is also expected to receive rainfall in areas including Gatundu, Thika, Juja, Ruiru, Limuru, Kikuyu, Kabete and Githunguri, while parts of Kajiado County — especially the northern, western and central regions — are likely to experience intermittent showers.

In Machakos County, rainfall is forecast in Kathiani, Machakos Town, Matungulu, Yatta and nearby northern areas.

The meteorological department has urged motorists and commuters to exercise caution while driving on slippery roads and to avoid attempting to cross flooded roads or rivers.

Residents have also been encouraged to stay updated on weather advisories issued by authorities.

Those living in flood-prone areas have been advised to take necessary precautions, including moving valuables to safer places and avoiding unnecessary travel during heavy rainfall.

Meanwhile, the Ministry of Health has issued a public health alert warning of a possible rise in water-borne and vector-borne diseases as the heavy rains continue in several parts of the country.

In a statement signed by Principal Secretary for Public Health and Professional Standards Mary Muthoni, the ministry warned that the ongoing March–April–May long rains could increase the risk of disease outbreaks if preventive measures are not taken.

The ministry noted that although the rains are important for agriculture and replenishing water resources, they may also create conditions that expose communities to health risks.

“The Ministry of Health wishes to alert the public that the ongoing March–April–May long rains are expected to continue in several parts of the country,” the statement said.

“While the rains are important for agriculture and water resources, they may also increase the risk of certain public health threats.”

According to the ministry, heavy rains and flooding can contaminate water sources, disrupt sanitation systems and create ideal breeding environments for disease-carrying vectors such as mosquitoes.
