  • Mostly near-average conditions have been observed across West Africa during this past week.
  • Heavy rain continues for portions of southern Ethiopia and Somalia, raising flooding concerns in East Africa.

1) Poorly distributed rainfall has resulted in drought, which has severely impacted ground conditions and already led to livestock death across parts of north-central and eastern Ethiopia.

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.

10 Jun 2015 description
  • 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.

03 Jun 2015 description

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

  • Very poor rains across northern Ethiopia expected to negatively affect “Belg” season cropping activities.

  • Average to above-average rains continue across parts of Kenya, Tanzania, and southern Somalia.

  • Some increase in rainfall expected across West Africa during the next outlook period.
  • Many areas of Sudan have reported flooding, house damages, and displaced people due to continued heavy rains.
07 May 2014 description

 Anomalously heavy rains were observed across much of South Sudan, increasing rainfall surpluses.

 Dryness continued across parts of Kenya and northeastern Uganda.

1) Consistently low and infrequent seasonal precipitation across some bimodal rainfall areas of northern Tanzania, southwestern Kenya, and northeastern Uganda have resulted in strengthening moisture deficits since late March. A continuation of suppressed rainfall in May is likely to adversely impact developing crops and pastoral conditions in the region.

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.

11 Sep 2013 description

1) The onset of the rainy season was delayed by more than four weeks across southeastern Sudan, northwestern Ethiopia, and southern Eritrea. This has delayed planting, reduced planting areas, and negatively impacted crops across the region. Though an increase in rainfall has been observed since the beginning of August, seasonal rainfall deficits have been sustained over many local areas.

28 Aug 2013 description

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

24 Oct 2012 description

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) 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.

03 Oct 2012 description

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.

05 Jul 2012 description

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.
