Saharan Dust Cloud Takes Unusual Path to Mississippi
14 Jul
Summary
- A new Saharan dust plume is taking an unusual path through Arkansas.
- Mississippi may see a brief break from dust around July 16-17.
- Saharan dust can suppress hurricane formation and affect air quality.
A substantial Saharan dust plume is currently enveloping the U.S. Gulf Coast, stretching from Florida to Texas. This airborne dust, originating from the Sahara Desert, is expected to take an unusual path, moving through Arkansas before reaching Mississippi.
Mississippi may experience a temporary clearing of the skies around July 16 and 17, offering a brief break from the dust. However, a fresh concentration is forecast to arrive by Saturday, July 19, making its way southeastward across the state. By July 20, the dust concentration is expected to return to mid-range levels.
This annual event, known as the Saharan Air Layer, can create dramatic sunsets and sunrises. It also plays a role in suppressing hurricane formation by cooling ocean surfaces and affecting storm development. While beneficial in this regard, the dust can negatively impact air quality, potentially causing respiratory issues for individuals with asthma or other sensitivities.
The dust plumes can carry bacteria and fungi and can significantly affect air quality, with larger plumes sometimes spanning areas as vast as the lower 48 states. Health precautions, such as using masks outdoors and air purifiers indoors, are advised during heavy dust periods. Eye protection is also recommended to prevent irritation.
