Countries with pronounced rainfall deficit included a few pockets in the border region between Ethiopia, Sudan and South Sudan, southeastern Ethiopia, central Somalia, and a few pockets in Tanzania.
Wetter Than Normal Conditions (Green and Light Green)
- Much Wetter than Normal (Dark Green): Concentrated heavily over the northern parts of the region including Sudan, South Sudan, parts of Eritrea, Ethiopia, northern Somalia and the equatorial region including eastern Uganda, central to western Kenya and northwestern Tanzania.
- Wetter than Normal (Light Green): Forms a wide band surrounding the darkest green area, covering most of countries highlighted above.
Near Normal Conditions (Light Blue)
- Near Normal: Predominantly observed in large parts of equatorial and northern parts of the region including Uganda, South Sudan, Ethiopia, Somalia, Eritrea, Kenya and Sudan.
Drier Than Normal Conditions (Yellow and Orange)

- The orange ('Much drier than normal') is evident across most of the countries highlighted.
No Rain (White)

High Rainfall Accumulation (Dark Green to Light Green)
- Highest Rainfall (201–300 mm and 101–200 mm): These values are extremely high for a 10-day period. Rainfall amounts between 101 and 300 mm was observed in isolated pockets within the central region of Ethiopia and western parts of Kenya.

- A few pockets in Somalia
- Most of southern Sudan and South Sudan.
- Large sections of Ethiopia (especially the western highlands).
- Western Kenya, Uganda, Rwanda, Burundi and a few pockets in Tanzania.
Moderate to Low Rainfall (Yellow and Orange)
- Low Rainfall (11–25 mm and 6–10 mm): These values typically ring the high-rainfall areas and transition into the driest zones. They are concentrated over:
- All countries in the GHA region.
Very Low or No Rain (Light Grey and White)
- Very Low Rainfall (1–5 mm): Forms a major transitional zone across northern Sudan, parts of Eritrea, Ethiopia, much of Somalia, northwestern and northeastern Kenya, and most parts of Tanzania.
