Plumes of African dust, also known as the Saharan Air Layer, have been common not only over the tropical Atlantic Ocean but parts of the United States as well. The pressure patterns over the Northern Hemisphere often steer these Saharan Air Layers westward across the Atlantic Ocean, and in some cases that dust can travel as far west as Texas and Central America.

Early this week, dust will return to parts of the southern US, traveling from Texas and Louisiana on Monday to the Mid-Mississippi River Valley by Wednesday, moderating as it moves.

Multiple days of dust will likely fill the skies of southeastern Texas and much of Louisiana, making for hazy or filtered blue sunshine and lower air quality, which may be harmful to some.

Thankfully, this dust will scoot out of the nation by late-week. The nice thing about this dust is that it stabilizes the Atlantic Ocean and suppresses tropical activity, keeping the US and Caribbean safe from any tropical cyclones.
