Heavy Rainfall is Expected in GHA Coupled with Heat Stress

  • Heavy rainfall (above 200mm) is expected from central to western Ethiopia. 
  • Moderate rainfall (50-200mm) is expected over parts of central to western South Sudan, central to western Ethiopia, and southern to southwestern Sudan amongst other Greater Horn of Africa (GHA)regions.
  • Light rainfall (less than 50 mm) is expected in central Sudan, eastern South Sudan, northern and eastern Uganda, parts of western and eastern Kenya, central to southern Somalia, part of eastern Ethiopia, Djibouti, and western Eritrea. 

Note: 1 mm of rainfall is equivalent to 1 liter of water per square meter.
