NAIROBI, Kenya — Kenya Meteorological Department has warned that heavy rainfall is set to intensify across several parts of the country between April 22 and April 27, raising the risk of flooding, strong winds and hazardous sea conditions.
In an advisory issued Tuesday, the agency said ongoing rains are expected to become heavier over the five-day period beginning at 3:00am on April 22 through to 9:00am on April 27.
“Rainfall is expected to continue across several parts of the country and is likely to intensify from April 22 to April 27,” the Met said.
The Coast is expected to bear the brunt of the downpours, with rainfall likely to exceed 40mm within 24 hours in some areas.
Counties on alert include Kwale, Mombasa, Kilifi, Tana River and Lamu. Inland areas, including Nairobi, parts of Kiambu and Murang’a, as well as the southeastern counties of Kitui, Makueni and Taita Taveta, are also expected to experience significant rainfall.
The department noted that the forecast carries a moderate probability (33–66%), meaning conditions are reasonably likely but not guaranteed.
Along the Coast, the Met warned of gusty winds exceeding 25 knots and sea waves rising above two metres, posing risks to marine activities.
“Sea waves are expected to reach heights of more than two metres along the Coast,” the Met said.
Fishermen and other ocean users have been urged to exercise caution as conditions may become unsafe.
Authorities cautioned that the rainfall could trigger flash floods, especially in urban areas and flood-prone zones, with downstream regions particularly vulnerable, even where rainfall may not be heavy locally.
“People in all the mentioned areas should remain alert for potential floods, flash floods and reduced visibility,” the advisory stated.
“Flood waters may occur in areas where it has not rained heavily, particularly downstream,” it said.
Motorists and pedestrians have been advised to avoid flooded roads and fast-moving water.
“To ensure safety, avoid driving through or walking in moving water or open fields,” the department advised.

The agency also highlighted the risk of lightning strikes, warning residents against taking shelter under trees or near metallic structures.
“Do not shelter under trees or near grilled windows to minimise exposure to lightning strikes,” the Met said.
Kenya is currently in the peak of its long rains season, which typically runs from March to May. In recent years, the season has become increasingly erratic, with more intense rainfall episodes linked to broader climate variability across East Africa.
Last year, heavy rains triggered widespread flooding and displacement in several counties, prompting renewed calls for improved early warning systems and disaster preparedness.
The Meteorological Department said it will continue to monitor weather patterns and issue updates as conditions evolve.
