Irregular rainfall to persist in Central America and Hispaniola; dryness worsens in West Africa

Africa Weather Hazards

A delayed onset of the rainy season, followed by poorly-distributed rainfall, has led to abnormal dryness across Burkina Faso, the northern parts of Ghana, Togo, and Benin, western and southern Niger, and northern Nigeria. The lack of rainfall over the past several weeks has delayed planting and negatively affected cropping activities over parts of this region.

Rainfall remains below average across parts of West Africa, Latin America, Ethiopia, and Djibouti

Africa Weather Hazards

  1. A delayed onset of the rainy season, followed by poorly-distributed rainfall, has led to abnormal dryness across Burkina Faso, the northern parts of Ghana, Togo, and Benin, western Niger, and north-central Nigeria.
