Dryness remains in the Greater Horn of Africa

Africa Weather Hazards

  1. Below-average and erratic rainfall since December has resulted in strong moisture deficits and degraded ground conditions. However, above-average rainfall since March has helped to alleviate seasonal dryness.

  2. Despite an increase in moisture following the passage of Tropical Cyclone Enawo during early March, long- term moisture deficits remain due to very poor rains earlier in the season throughout central and eastern Madagascar.

  3. Inconsistent rainfall and dry spells since late December has led to strengthening moisture deficits and deteriorating ground conditions across many parts of western Angola.

  4. Despite improvement in rainfall during late March and early April, below-average rainfall accumulations since late February have resulted in moderate to locally strong moisture deficits in many parts of southern South Sudan, Kenya, southern Ethiopia, southern Somalia, and northern Tanzania.

  5. Above-average rainfall across northwestern Namibia and western Zambia since early March has increased the risk for flooding along the Cuvelai Iishanas river basin and the Zambezi floodplains over northern Namibia.
