Large rainfall surpluses remain across broad areas of Southern Africa

Africa Weather Hazards

  1. Since late December, enhanced seasonal rainfall has resulted in large moisture surpluses and several floods. The risk of additional flooding remains high throughout Botswana, Zimbabwe, Mozambique, Malawi, Zambia, and southwestern Tanzania.

  2. Below-average and erratic rainfall since December has resulted in strong moisture deficits, low soil moisture, and poor crop prospects across parts of northeastern Mozambique.

  3. Enhanced rainfall during and after the passage of tropical cyclone Enawo is expected to sustain the risk of localized flooding, inundated river basins and other adverse ground impacts over northern Madagascar.

  4. Despite a robust increase in moisture following the passage of Tropical Cyclone Enawo during early March, considerable longterm moisture deficits remain due to very poor rains earlier in the season throughout the northern Madagascar.

  5. Inconsistent rainfall and dry spells since late December has led to strengthening moisture deficits and deteriorating ground conditions across many parts of western Angola.
