    • 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.
