Dust from the Sahara Desert blows westward, off the coast of West Africa, including the countries of Western Sahara, Mauritania, Senegal, the Gambia and Guinea Bissau.
Dust from the Sahara Desert also veiled the skies over Chad, Niger and Nigeria. The dust is less thick in Chad and by Lake Chad, where the three countries share borders. The dust also clears in northern Niger, above the Aïr Mountains.
