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, poor air quality, and the potential for vibrant morning and evening skies.

A dust plume that has been traveling across the Atlantic may later spread as far as Texas and Georgia as a weather system breaks it apart.
