Increased rainfall to bring some relief to anomalously dry areas of South Africa

Africa Weather Hazards

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

  2. Significantly heavy rains within the last two weeks has resulted numerous floods, thousands of displaced people and fatalities throughout several provinces in Kenya.
    Flooding has been particularly severe along the Thanantu and Tana rivers.

  3. Above-average seasonal rainfall has led to above-normal river levels along the Shabelle and Jubba River basins.
    Although precipitation has diminished during the middle of November, additional rains are expected to sustain the risk for flooding in the region.

  4. Despite the recent increase in rainfall across Kenya, 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. 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.

  6. Very low and infrequent precipitation in southern Africa has resulted in significant early season moisture deficits, particularly in the KwaZulu-Natal region of South Africa, Swaziland, and southern Mozambique. The continuation of low rainfall in late November and early December is expected to rapidly worsen ground conditions and impede cropping activities due to higher-than-normal temperatures and poor rains from last year’s monsoon, which has already depleted water resources.
