Those outflow boundaries are only a large rush of air.

That dust lifts into the air and will get lofted by the commerce winds and is carried 1000’s of miles throughout the Atlantic.

High stress over Bermuda retains that dust to the south and steers it into the Caribbean and ultimately into the Gulf of Mexico, and that’s what provides us the hazy skies.
