The Kenya Meteorological Department (KMD) has issued a heavy rainfall advisory and warned of heightened flood and displacement risks in 11 counties. In the advisory dated 21 April, Kenya Met indicated that rainfall is expected to intensify across several parts of the country from the afternoon of 22 April through the morning of 27 April.
The weather forecast notes that some places may receive very heavy rain of over 20 millimeters in just one day, with the worst downpours expected along the Coast, in the Northeastern region, and in parts of Western and Central Kenya.
According to Kenya Met, coastal areas could experience rainfall exceeding 30 millimeters in 24 hours, while strong winds exceeding 25 knots (12.5 meters per second) may accompany the rains.
Ocean wave heights of more than two meters are also expected along the coast.
“Rainfall is expected to continue across several parts of the country. From 22nd April to 27th April 2026, the rainfall is likely to intensify, with accumulations exceeding 20mm in 24 hours over the Coast, as well as parts of the Northeastern lowlands,” read part of the advisory.

Kenya Met has urged residents in the affected counties to remain alert and take precautionary measures, warning that floodwaters may also occur in places far from rivers due to overflowing drainage systems and surface runoff.
The advisory cautions residents against attempting to walk or drive through moving water and advises against sheltering under trees or near grilled windows during storms, citing lightning risks.
“To ensure safety, residents are advised to avoid driving through or walking in moving water or open fields, not to shelter under trees or near grilled windows to minimize exposure to lightning strikes, and to take precautions while engaging in maritime activities,” stated the Kenya Met.
Those engaged in maritime activities have been asked to exercise caution due to rough sea conditions expected along the coast.
Emergency response agencies, including the Kenya Red Cross, have been placed on alert as the country braces for possible flash floods, property damage and displacement of households in vulnerable areas.
The Kenya Met said it would continue to monitor the situation and issue updates should there be any significant changes in weather conditions.
