Questions? An extensive dust storm in late February carried debris over the Atlantic Ocean, en route to the Amazon Basin. That means a more significant amount of dust than usual was able to accumulate just off the west coast of Africa. By July 19, a massive dust storm had crossed the Atlantic towards southern Florida.

This image shows two different areas of dust plume activity. More dust can also mean fewer storms because it blocks incoming sunlight, leading to cooler ocean temperatures.
The dust is expected to reach the Caribbean later this week, and may even make it to parts of the United States next week.
