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

21 Aug 2013 description

 A favorable distribution of rainfall was observed across a wide portion of Africa during the past week.

1) A delayed start of the rainfall season across northwestern Ethiopia, southern Eritrea, and bordering areas in Sudan has negatively impacted cropping activities, including planting. After this past week’s heavy rainfall, moderate rains are forecast during the next outlook period, which could help to alleviate dryness over the region.

05 Dec 2012 description

1) Moisture deficits remain following a mid-season dry spell that occurred in early November and recent drier than average conditions. With a shortened recovery period in the next several weeks, this could result in a deterioration of pastoral and agro-pastoral conditions, and possible crop yield reductions by the end of season throughout parts of Ethiopia, Somalia, Kenya and eastern Tanzania.

28 Nov 2012 description

1) The return of below-average rainfall during the last week has re-strengthened moisture deficits following a mid-season dry spell that occurred in early November. With a shortened recovery period in the next several weeks, this could result in a deterioration of pastoral and agro-pastoral conditions, and possible crop yield reductions by the end of season throughout parts of Ethiopia, Somalia, Kenya and eastern Tanzania.

22 Nov 2012 description

Increased rainfall during the last week helped to improve mid-season dryness across Kenya and Somalia, however moderate seasonal deficits remain for many local areas.

1) Even with a reduction of precipitation last week, several weeks of above-average rainfall has led to significant moisture surpluses. An elevated potential for moderate to heavy rainfall may trigger additional flooding, damage local infrastructure, and negatively impact cropping activities throughout Uganda, Kenya, northern Tanzania,
Rwanda and Burundi.

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.

17 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.

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.

26 Sep 2012 description

1) Both anomalous seasonal rainfall and northward position of the Inter-Tropical front has favored breeding conditions for desert locusts over the southern Mauritania-western Mali border, central Niger-eastern Mali, Chad, and east-central Sudan. The continuation of above-average rainfall during September could lead to locust outbreak across many regions.

19 Sep 2012 description

1) Strong easterly wave activity across West Africa is expected to enhance precipitation amounts during the next week, which may trigger localized flooding over parts of eastern Guinea, southeastern Senegal, and border areas of Mali and Cote d’Ivoire. Continued oversaturation of ground conditions in Guinea also heightens the risk for water-borne diseases outbreaks.

12 Sep 2012 description

1) Heavy rains have resulted in fatalities and massive destruction in South Darfur, the northern Bahr el Ghazal, Warrap, and Jonglei states of South Sudan. Flooding potential remains as above-average rains are forecast during the next week.

2) Since July, heavy rains causing flooding and inundation along the Niger and Benue Rivers have led to the displacement of thousands of people and many fatalities in eastern Nigeria. Enhanced rainfall forecast could exacerbate the ground conditions.

05 Sep 2012 description

1) Heavy rains have resulted in fatalities and massive destruction in South Darfur, the northern Bahr el Ghazal, Warrap, and Jonglei states of South Sudan. Flooding potential remains as heavy rains are forecast during the next week.

2) Heavy downpours left one dead in the Gambia during the past week. Heavy rains have persisted, exacerbating Cholera outbreak across Sierra Leone and Guinea. Concerns for flooding and Cholera spreading remain as heavy rains are again forecasted.

29 Aug 2012 description

1) Heavy rains have resulted in fatalities and massive destruction in South Darfur and the northern Bahr el Ghazal, Warrap, and Jonglei states of South Sudan during the past week. Flooding potential remains as heavy rains are forecast during the next week.

2) Heavy downpours killed four people in Dakar and central Senegal during the past week. Heavy rains persisted, potentially exacerbating Cholera outbreak across Sierra Leone and Guinea. Concerns for flooding and Cholera spreading remain as heavy rains are again forecasted.

23 Aug 2012 description
  • Wet conditions prevail across West Africa and eastern Africa.
  • Hatching eggs and low-density locusts increase the potential for locust outbreak over many regions.

1) Heavy rains during the past week have caused flooding, destroying more than two thousand homes in El Fasher, Sudan. Flooding potential remains as locally heavy rains are forecast to continue during the next week.

09 Aug 2012 description
  • Torrential rains continue across the western portions of West Africa.
  • Widespread heavy rains were observed across eastern Africa.
  • Hatching eggs and low-density locusts increase the potential for locust outbreak over many regions.

1) Heavy downpours have resulted in fatalities and displaced population over North and Central Darfur regions of Sudan during the past week. Flooding potential remains as heavy rains are forecast to continue during the next week.

02 Aug 2012 description

1) Above-average rains observed in western Sudan and eastern Chad during the past thirty days have caused localized flash floods. With additional heavy rain forecast for the next week, localized flash flooding could occur.

25 Jul 2012 description

1) Although rainfall has been consistent in the western parts of the country since the middle of May, accumulated rainfall has been erratic and below-average since the start of the Kiremt rainy season in June in portions of western Ethiopia including the Oromiya region. Another week of increased rainfall is forecast during the next seven days which will continue to help reduce moisture deficits and aid cropping activities in the region.

18 Jul 2012 description

1) The five-week delay in the onset of the March-May seasonal rainfall and the erratic and below-average nature of the Kiremt rains have 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 well below-average since the start of the Kiremt rainy season in June.

11 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 well below-average since the start of the Kiremt rainy season in June. Another week of increased rainfall is forecast during the next seven days. This could help continue to reduce moisture deficits and aid cropping activities in the region.
