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?
Satellite photos from Friday morning showed two dust plumes, one in the western Caribbean and one just east of the Windward Islands.
Unhealthy air quality was observed between Cuba and Venezuela, where dust concentrations are highest.
