Heavy to extremely heavy rainfall is expected to continue in most parts of Kenya, Rwanda, Burundi, northern Tanzania, and southern Somalia. Given the heavy rains, hazards such as landslides, riverine, and flash floods are likely to continue in susceptible areas. National governments and humanitarian organizations are encouraged to enhance monitoring, preparedness, and emergency response. 

Total rainfall 

• Heavy rainfall (greater than 200mm) is expected in the eastern regions of Rwanda and Burundi, north-western Tanzania, and western and central Kenya.
