Dust isn't the only threat out there, especially for those with respiratory problems. Smoke from Canadian wildfires is moving south into the U.S., although it is not expected to last as long or be as bad in Florida as it was almost two years ago.

A plume of thick dust suspended in the atmosphere is moving westward across the Caribbean Sea and is expected to reach Florida on Wednesday. Areas in its path can expect haze, locally poor air quality and the potential for vibrant morning and evening skies.

Hilton Head is experiencing lower air quality due to Canadian wildfire smoke. Just as that haze will leave the state, dust from the Sahara Desert will arrive and poor air quality will likely continue.
