Start of season remains slow in parts of West Africa, abnormal dryness continues in Central America and Haiti

Africa Weather Hazards

  1. A delayed onset of the rainy season, followed by poorly-distributed rainfall, has led to abnormal dryness across southern Burkina Faso, the northern parts of Ghana, Togo, and Benin, and north-central Nigeria. The lack of rainfall over the past five weeks has delayed planting and negatively affected cropping activities over many local areas of the region.

  • Abnormal dryness has settled in across West Africa due to insufficient rains since the start of the season.

  • Seasonal rains continue in Eastern Africa.

1) An uneven distribution of the March-May rains had adversely impacted crops and ground conditions over the SNNP, central and Belgproducing areas of Ethiopia, eastern Eritrea, and Djibouti. As the March-May season had already ended, recovery is unlikely.

- The onset of the rainy season has been sluggish over West Africa, but an increase in rainfall is expected during the next week.

1) An uneven distribution of the March-May rains had adversely impacted crops and ground conditions over the SNNP, central and Belg-producing areas of Ethiopia, eastern Eritrea, and Djibouti. As the March-May season has already ended, recovery is unlikely.

16 Oct 2013 description

1) Since June, insufficient and poorly-distributed rainfall has led to large rainfall deficits across the Gulf of Guinea countries and has reduced maize yields in Ghana, southern Togo and in southwestern Nigeria. Although seasonal rainfall has increased during the second peak of the bi-modal rainfall season, below average thirty and sixty day rainfall totals have continued. Average rainfall is forecast during the next week.

 A slight reduction in rainfall was observed across West Africa, while seasonal rains continued over eastern Africa during the past week.

1) With seasonal rains ending and as vegetation dries out, locust swarms have formed in Chad and are expected to form shortly in Niger and Mali. Swarms are then expected to migrate towards the north as well as potentially into cropping areas in western/central Mali.

1) Both anomalous seasonal rainfall and the northward position of the Inter-Tropical front during the past several months have favored breeding conditions for desert locusts over southeast Mauritania-western Mali, central Niger-eastern Mali, Chad, and east-central Sudan. With seasonal rains ending and as vegetation dries out, locusts are expected to concentrate and migrate towards the north as well as potentially into cropping areas in Mali and Niger.

1) The five-week delay in the onset of the March-May seasonal rainfall had significantly impacted ground moisture and cropping activities in the central region of Ethiopia. Although rainfall has been consistent in the western parts of the country since the middle of May, accumulated rainfall has been below-average. Another week of increased rainfall is forecast during the next seven days. This could help to reduce moisture deficits and aid cropping activities in the region.
