This is one big dust cloud coming from the Sahara! It’s going to make for some amazing sunsets in the Gulf and Texas, and probably quite a mess of cars and buildings.
Normally, hundreds of millions of tons of dust are picked up from the deserts of Africa and blown across the Atlantic Ocean each year. That dust helps build beaches in the Caribbean and fertilizes soils in the Amazon. It can also affect air quality in North and South America. There’s a good piece here that explains more.
Oh, and it’s the Solstice this Saturday.
