Analysis by BBC Weather presenter Simon King
Dust and sand storms are not uncommon in desert regions of the world. Winds can whip up dust, up to 2 billion tons each year, high in our atmosphere and is transported many miles from the source.

Dust and sand provide a source of nutrients for ocean ecosystems, but can also affect the climate and health of humans with respiratory problems.
Dust leaving the Sahara into the Atlantic is a common occurrence and is known as the Saharan layer of dry air. Later in the hurricane season it can inhibit the growth of tropical storms that develop around Cape Verde and the mid-Atlantic.
However, during the last week we have had an unusually large area of dust that crosses the Atlantic and affects Central and North America. This is going to happen over the weekend. Meanwhile, another large area of dust has been seen in satellite imagery emerging from the Sahara and crossing the Atlantic.
Poor visibility and air quality are forecast to continue in parts of the Caribbean and Central America over the coming week.
On Sunday, it was the Venezuelan capital Caracas that saw its neighborhoods surrounded by mists.
