Eastern Africa’s regional climate monitoring centre, ICPAC, has issued a warning over the possibility of heavy rainfall across the region at the end of the week.
The agency has called on people to be “vigilant for flood risk”.
ICPAC says the rainfall, ranging between 50-70mm (2-2.75in), is expected on Friday in some parts of the region.
Areas likely to be affected cover a wide band stretching from north-west Somalia, through Ethiopia and western Kenya and then into central Tanzania
Kenya’s meteorological agency says heavy rainfall above 100mm (3.9in) may fall in some parts of the country.
Some areas are already receiving higher than normal rainfall.
The Kenya Red Cross says three landslide incidents have occurred in central Kenya, although there have been no reports of casualties.
Heavy rainfall and flooding have affected areas across eastern Africa since July. The rain intensified in October.
