In the coming days, weather patterns across the Greater Horn of Africa are expected to shift noticeably.

Much of the Greater Horn of Africa will experience heavier-than-usual rainfall, especially across western Ethiopia, southern Sudan, and the coastal areas of southern Somalia, Kenya, and Tanzania. Even parts of central Tanzania and Rwanda are likely to receive more rain than they typically do this time of year.

In many areas, such as South Sudan, central southern Sudan, and the western parts of Kenya, Uganda, and Ethiopia, moderate rainfall is expected, ranging between 50 to 200 millimeters.

Southern coastal Somalia and coastal Tanzania will see similar amounts. Meanwhile, lighter showers (less than 50 millimeters) are likely to fall over Rwanda, Burundi, most of Uganda, and parts of Sudan and Somalia stretching from the center to the north.

Some locations, particularly in western Ethiopia and isolated areas of South Sudan, might experience very heavy downpours, with rainfall reaching levels seen only about 10% of the time in records. To put it into perspective, just 1 millimeter of rain equals one liter of water spread over a square meter.

Alongside the rains, temperatures are expected to rise above average across much of the region. In the hotter zones, like southeastern Sudan, coastal Eritrea, northeastern Ethiopia, Djibouti, and northern Somalia, temperatures could soar above 32°C.

A large portion of the Greater Horn of Africa region, including Sudan, South Sudan, Uganda, northern and eastern Kenya, Somalia, and parts of Ethiopia and Tanzania, will experience warm to hot conditions, with temperatures ranging from 20°C to 32°C.

Yet, there will still be places where the air stays cool and fresh. Rwanda, Burundi, the highlands of Ethiopia, and parts of western Kenya, southwestern Uganda, and central to southwestern Tanzania are expected to enjoy milder temperatures below 20°C.

Interestingly, central to northern Sudan might even experience cooler-than-usual conditions, a contrast to the broader warming trend.

Finally, with the rising heat in the Greater Horn of Africa, heat stress levels are likely to climb, particularly in the Afar region of Ethiopia, and across southern Sudan, South Sudan, Eritrea, Djibouti, and Somalia. People in these areas may need to take extra care to stay cool and hydrated.
