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.

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.

Rainfall deficits persist in areas of Ethiopia, West Africa, and Central America

Africa Weather Hazards

27 May 2015 description
  • Beneficial rainfall in the driest regions of Ethiopia and Djibouti; little rainfall for eastern areas of the Horn of Africa.

  • Moisture surpluses emerge in far western portions of the Western Africa region, while deficits remain to the east.

20 May 2015 description
  • Most of the greater Horn of Africa observed a decrease in rainfall over the previous week.
  • Early season rainfall remains below normal for portions of West Africa.

1) Since late December, an unseasonable distribution of monsoonal rainfall has resulted in anomalous dryness and poor ground conditions unfavorable for crops across several local areas in southern Angola, Namibia, Botswana, Zimbabwe, Lesotho, and South Africa.

13 May 2015 description
  • The first substantial rains in many weeks across rift valley regions of Ethiopia this past week may benefit grazing activities and water resources.

  • Rainfall becomes more seasonably well distributed across portions of West Africa.

1) Since late December, an unseasonable distribution of monsoonal rainfall has resulted in anomalous dryness and poor ground conditions unfavorable for crops across several local areas in southern Angola, Namibia, Botswana, Zimbabwe, Lesotho, and South Africa.

06 May 2015 description
  • A continued absence of rainfall across northern Ethiopia expected to adversely affect crop and pastoral conditions.

  • Delay in onset of early monsoon rainfall continued through the 3rd dekad of April across a large portion of western Africa.

1) Since late December, an unseasonable distribution of monsoonal rainfall has resulted in anomalous dryness and poor ground conditions unfavorable for crops across several local areas in southern Angola, Namibia, Botswana, Zimbabwe, Lesotho, and South Africa.

29 Apr 2015 description
  • A continued absence of rainfall across northern Ethiopia expected to adversely affect crop and pastoral conditions.
  • Largely suppressed early season rains observed during the 2nd dekad of April over much of West Africa.

1) Since late December, an unseasonable distribution of monsoonal rainfall has resulted in anomalous dryness and poor ground conditions unfavorable for crops across several local areas in southern Angola, Namibia, Botswana, Zimbabwe, Lesotho, and South Africa.

09 Oct 2013 description

 After a week of heavy rain, rains across bi-modal West Africa were light and below-average.

 Anomalous heavy early-season rainfall was observed across much of Mozambique.

02 Oct 2013 description

Heavy rains were observed across dry areas in bi-modal regions along the Gulf of Guinea.

1) A pronounced late start of seasonal rainfall in July has delayed planting by approximately one month and has reduced crop yields across many parts of Sudan. The onset of continuous seasonal rainfall during September and October now remains critical for several local areas that have planted late. However, with seasonal rains quickly coming to an end, little time remains for additional rainfall.

25 Sep 2013 description

 Some relief to dryness is expected across the Gulf of Guinea region during the end of September.

1) A pronounced late start of seasonal rainfall in July has delayed planting by approximately one month and has reduced crop yields across many parts of Sudan. The onset of continuous seasonal rainfall during mid to late September now remains critical for several local areas that have planted late.

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.

04 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.

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.

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.
