Heavy rains have continued for far western Gulf of Guinea, while much drier conditions prevailed farther east across West Africa.

Heavy rain continues for portions of East Africa raising flooding concerns.

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

Africa Weather Hazards

03 Dec 2014 description
  • Below-average rains observed over a wide portion of Southern Africa during the past week.
  • Seasonal rains coming to an end in the Greater Horn of Africa.

1) Low and poorly distributed seasonal OctoberDecember, Deyr, rains have led to moisture deficits and deteriorated ground conditions throughout local areas of southern Somalia, central Kenya, and coastal Tanzania. Recent rains have relieved dryness over most parts, but rainfall deficits have persisted over many localized areas.

26 Nov 2014 description
  • Scattered moderate to heavy rains observed in southern Somalia and eastern Kenya.

  • Below-average rains persist in central Angola, southern Zambia, and eastern South Africa.

1) Low and poorly distributed seasonal “Deyr” rains have led to strengthening moisture deficits and deteriorating ground conditions throughout several local areas in southern Somalia, eastern Kenya, and coastal Tanzania. Recent rains have relieved dryness over most parts, but rainfall deficits have persisted over many localized areas.

19 Nov 2014 description
  • A short period of increased rains helped to relieve many anomalously dry areas in the Greater Horn.

  • Strengthening moisture deficits continue throughout parts of northern Angola and eastern Zambia.

1) Low and poorly distributed seasonal “Deyr” rains have led to strengthening moisture deficits and deteriorating ground conditions throughout several local areas in southern Somalia, eastern Kenya, and coastal Tanzania. The persistence of drier than average rainfall in November is likely to negatively affect crop and pastoral areas in the region.

12 Nov 2014 description
  • Despite a small increase in moisture during the last week, many areas in the Greater Horn remain anomalously dry.

  • Suppressed seasonal rains lead to strengthening moisture deficits across several regions in southern Africa.

03 Apr 2014 description
  • The continued suppression of rainfall suggests an early cessation of the monsoon over parts of southern Africa.
  • Increased rains observed over the Afar and highland regions of Ethiopia during late March.

1) Heavy and above-average rains over the past few weeks have increased rainfall surpluses and resulted in flooding across the Omusati region along the Angola-Namibian border. The inundation has led to the closure of several schools in the area. Moderate to heavy rains are forecast to continue during the next week.

26 Mar 2014 description

A decrease in rainfall has been recorded over Southern Africa during the past week.

A favorable start of the March-May season has been observed over the Greater Horn of Africa.

19 Mar 2014 description
  • A favorable distribution of rainfall was observed over Southern Africa during the past week.

  • Widespread and above-average rains fell across the Greater Horn of Africa during the past week.

29 Jan 2014 description

A seasonable distribution of precipitation was received throughout much of southern Africa during the last week.

1) Portions of Tanzania have experienced below average seasonal rainfall since late November. Poorly distributed rains since early December have also led to developing dry conditions in the Morogoro and Pwani provinces further east. The anomalous dryness has already negatively impacted vegetation conditions in the region.

31 Dec 2013 description

 Heavy rains are expected in eastern Southern Africa, increasing risks for localized flooding during the next outlook period.

1) Both delayed start and poor distribution of rainfall since the beginning of the October-December rainy season have led to moisture deficits and below-average ground conditions across northern Kenya and parts of southern Somalia. With the season already coming to an end, the potential for recovery is unlikely.

06 Nov 2013 description
  • The passage of a weak tropical disturbance is expected to produce heavy amounts of rainfall over northern Somalia.
  • Poor October rainfall across parts of central and eastern Kenya, as well as, southern Somalia lead to strengthening moisture deficits in the region.

1) The development of a tropical disturbance in the northwestern Indian Ocean is expected to move west and bring significantly heavy amounts of rainfall across the Gulf of Aden and Somalia.
