Elevated risks of flooding in Kenya, South Sudan, and Somalia

Africa Weather Hazards

  1. Persistent belowaverage rainfall since August over several areas of Ghana, Togo, and Benin has led to strong moisture deficits and a degradation of ground conditions. However, Increased rainfall since October has significantly improved ground conditions.

  2. Several consecutive weeks of above-average rainfall has increased the risk for flooding in the White Nile, Jonglei, and Eastern Equatorial provinces of South Sudan.

  3. Abundant rains have caused flooding, river inundations, and road closures in many parts of Kenya, including the vicinity of Lous, Meru, Nairobi, Elgeyo Marakwet, Baringo, and Garissa.
    Elevated risks for flooding are maintained as locally heavy rain is expected to continue during the next week.

  4. Poorly distributed rainfall since the beginning of October has resulted in pockets of strong seasonal moisture deficits throughout parts of central Kenya and northeastern Tanzania.

  5. Several weeks of above-average rains have led to swelling rivers in Somalia and southern Ethiopia. The Shabelle and Jubba Rivers are forecast to be near or above flood stage. Locally heavy rainfall due to ambient tropical cyclone passages in the Gulf of Aden is expected to increase flooding risks in central and northern Somalia.

  6. Poorly-distributed rainfall since September has resulted in increased early season moisture deficits and degraded ground conditions throughout several provinces of northern and central Angola.

  7. Very low and poorly-distributed precipitation has led to a prolonged delay of seasonal moisture for early-season cropping activities. Combined with higher-than-normal temperatures, the developing dryness is worsened by pre-existing ground conditions associated with a poor monsoon last year and may lead to an intensification of negative impacts.
