Prolonged high concentrations of dust are expected over metro Atlanta and much of Georgia over the next three to four days.
The large Saharan dust plume, described as one of the biggest of the 2025 season, has already reached Florida as of June 4 and 5, after traveling over 5,000 miles from North Africa.
It is expected to spread to other Southeastern states, including Georgia, the Carolinas, Louisiana, Mississippi, Alabama, and Texas, through the weekend. The dust is causing hazy skies, reduced visibility, and vibrant sunrises/sunsets due to light scattering by dust particles.
People who experience adverse effects due to dust exposure should take precautions.
Saharan dust, carried by the Saharan Air Layer (SAL), is a well-documented phenomenon where dust from the Sahara Desert travels across the Atlantic Ocean, often reaching the southeastern U.S., Gulf Coast, and Caribbean. The references confirm that a significant Saharan dust plume is already affecting the U.S. in early June.
Potential Health Impacts
Respiratory Effects: The dust contains fine particulate matter (PM2.5 and PM10), which can be inhaled deeply into the lungs, irritating airways and triggering:
- Coughing, wheezing, or shortness of breath
- Throat and nasal irritation
- Worsening of allergies or sinus issues
- Vulnerable Populations:
- Children: Developing lungs and faster breathing rates increase susceptibility.
- Older Adults: Reduced lung function or existing health issues heighten risk.
- People with Respiratory Conditions: Those with asthma, COPD, bronchitis, or emphysema may face exacerbated symptoms, potentially leading to asthma attacks or the need for medical care.
- Heart Disease Patients: Dust can inflame blood vessels, raising risks for cardiovascular issues in those already at risk.
- Healthy Individuals: May experience mild symptoms like itchy eyes, scratchy throat, or minor coughing, especially during heavy dust concentrations.
