The Kenya Meteorological Department has issued a heavy rainfall advisory warning of heavy downpours across several parts of the country from April 22 to April 27, 2026, raising concerns over possible floods, strong winds and hazardous sea conditions.

In the advisory released on April 21, 2026, the department said rainfall is likely to exceed 20 millimetres within 24 hours in the Coastal region and parts of the Northeastern and Southeastern lowlands.

The rains are expected to be accompanied by strong winds of over 25 knots and ocean waves rising above two metres along the Coast.

“Rainfall is expected to continue across several parts of the country. From April 22 to  April 27, 2026, the rainfall is likely to intensify, with accumulations exceeding 20mm in 24 hours over the Coast, as well as parts of the Northeastern and Southeastern Lowlands,” Kenya Met stated.

Affected areas

Areas likely to be affected include Kwale, Mombasa, Kilifi, Tana River, Lamu and Garissa counties, as well as parts of Wajir, Mandera, Taita-Taveta, Kitui and Makueni.

The weatherman cautioned that the ongoing rains may trigger floods and flash floods, even in areas that may not receive heavy rainfall directly, particularly in downstream regions. Residents have also been warned of poor visibility and the risk of lightning strikes.

“People in all the mentioned areas should remain vigilant for potential floods, flash floods, and poor visibility. Note that flood waters may occur in areas where it has not rained heavily, particularly downstream,” the advisory stated.

Public advisory

Authorities have urged the public to avoid walking or driving through moving water and to stay away from open fields and trees during storms.

The advisory stated that those engaging in maritime activities have also been advised to exercise caution due to strong winds and high waves.

“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 minimise exposure to lightning strikes and to take precautions while engaging in maritime activities,” Kenya Met stated.

The weathermen said they will continue to monitor the situation and provide updates should there be any changes in the forecast.
