Heavy to weighty rainfall is expected in parts of south-eastern Ethiopia extending into parts of central Somalia, and northern and southern parts of Uganda.  This may lead to flooding in low-lying areas.  Additionally, warmer-than-average temperatures are expected over most parts of the Greater Horn of Africa (GHA).

• Moderate rainfall (50-200mm) is expected over Burundi, Rwanda, north-western Tanzania, Uganda, western and northeastern Kenya, South Sudan, central and southern Somalia, and parts of western and southern Ethiopia.

Flood Update

Heavy to weighty rainfall is expected in parts of south-eastern Ethiopia extending into parts of central Somalia, northern and southern parts of Uganda, and isolated areas in northern Kenya, western Ethiopia, and South Sudan. This may increase the likelihood of isolated flash flood events in flood-prone areas with high risk anticipated over south-eastern Ethiopia and southern Somalia.
