Saharan dust transported to the United States is regular, specifically from late June to mid-August, the CDC said.
Every single calendar year the atmosphere transfers many hundred million tons of the dust, designed of minerals this kind of as iron and phosphorous, throughout the Atlantic to the Caribbean, Central America and South The united states. The dust largely has an effect on Puerto Rico but can access states, including Florida and Texas.
