It's Saharan dust season in the Atlantic, the time of year when massive clouds of dust from Africa's Sahara Desert are carried westward by winds, sometimes traveling thousands of miles to the United States.
Where is the dust now?
Unhealthy air quality was observed across much of the Caribbean Tuesday morning, where dust concentrations were highest. A large area of dust was just offshore from South Florida and near the Bahamas.
When will the dust hit the United States?
