Heavy rainfall in the western Gulf of Guinea triggers flooding and damages to infrastructure

Africa Weather Hazards

  1. Above-normal rainfall since July has elevated the risk for flooding in southeastern Sudan and parts of western Ethiopia. Heavy rainfall is forecast for mid to late August.

  2. Despite increased moisture in early August, poorly distributed rainfall across parts of Eritrea, Ethiopia,
    Djibouti, and western Somalia since early July have led to high seasonal moisture deficits.

  3. Little to no rainfall received last month and the rapid development of moisture deficits indicate a delayed start of season in many areas in northern Senegal and southern Mauritania.

  4. Locally heavy rainfall during the last week triggered floods, mudslides, damages to infrastructure, and fatalities in western Sierra Leone. With well above-average moisture conditions in place since early July, rainfall in mid-August may trigger additional flooding throughout Senegal, The Gambia, Guinea-Bissau, Guinea and Sierra Leone.
