This TOMS aerosol movie, which spans the interval June 13 through 21, 2001, shows a cloud of African dust crossing the Atlantic and raining bits of the Sahara Desert over the Caribbean.
We've found that dust outbreaks, along with other factors, seem to be shifting tropical precipitation (which typically occurs in a narrow band where winds from the northern and southern hemispheres come together) northward by about four or five degrees, which is about 240 to 280 miles at the equator.
The Caribbean islands and south Florida are bracing for their next major weather event. It's not a hurricane, though; it's a dust storm, an enormous cloud of red sand. And get this: It's kicked up in the Sahara Desert and rides the trade winds all the way across the Atlantic.
Scientists say those are not clouds; that is dust from the Sahara desert. Giant sand storms — often larger than Spain — routinely blow all the way across the Atlantic, reaching South America, the Caribbean, and the southeastern United States.
"There have been times when airports in the Caribbean have been closed down for lack of visibility from these dust storms," said Eugene Shinn, a senior geologist at the U.S. Geological Survey in St. Petersburg, Fla. "It shows we're all linked together in one way or the other, that's for sure."

I've actually got slightly pinkish skies here in the Upstate. I don't know what in the world is going on. Anyway, I would watch the news tomorrow for a giant fire or some kind of plant explosion.
