Saharan dust is in the process of a 6,000-mile journey to the United States, and while the dust is a normal occurrence in the United States, more is expected this year than a normal year.
The plume is so large it can be seen from the International Space Station. The air quality in the Caribbean fell to “hazardous” do to the cloud Tuesday.
The United States should see the cloud reach land sometime Wednesday and will reach as far as Indiana in the coming days.
