Weatherman Warns of Flood-Risks

The department warned that the expected weather conditions could trigger flooding and flash floods, as well as poor visibility and rising river levels, even in areas that may not receive heavy rainfall.

KMD also cautioned about possible landslides in hilly regions such as the Aberdare ranges and Mt Kenya, as well as hazardous marine conditions along the coast.

As of April 24, Kenya Red Cross has reported that more than 300 households have been affected by flooding in Lunga Lunga Sub-County, Kwale County, following heavy rains that have disrupted movement and access to key areas.

The weather department said sections of the Likoni–Lunga Lunga Road in Perani, Ramisi and Lunga Lunga have been rendered difficult to pass, slowing transport and emergency access in the region.

It added that response teams are on the ground conducting assessments, raising awareness and working with partners to support affected families as flood response efforts continue.
