South Florida in the Last Throes of Saharan Dust Season
South Florida in the Last Throes of Saharan Dust Season, Another Large Plume Expected Late This Weekend
South Florida is in the last throws of the Saharan dust season, but another large plume could move back into the region late this weekend. In fact, AirNow.gov is forecasting the air quality to go from the “good” to “moderate” range by Sunday.
The Dust Arrives
The dust is expected to arrive on Sunday and Monday, with the thickest cloud expected to go right over Cuba and the Bahamas. Saharan dust is kicked up by thunderstorms in Africa, and if the trade winds are just right, it can travel the entire Atlantic basin and end up in our backyard.
Positive and Negative Impacts of Saharan Dust
The Benefits
There are some benefits to this phenomenon. It’s been linked to beautiful sunrises and sunsets, along with a noticeable glow in the sky. It’s also been known to transport nutrients like iron across the ocean and deposited on land. These nutrients act like fertilizer and is at least partially responsible for some of the nutrient-rich soil in the Amazon.
The Risks
There are also some known negative impacts from these particles. Besides being hazardous for health, especially for persons with respiratory issues like asthma, Saharan dust has been known to negatively impact coral reefs. It’s also linked to algae blooms.
Conclusion
While Saharan dust can have both positive and negative impacts, it’s essential to be aware of its effects on our environment and health. As the season winds down, it’s crucial to take necessary precautions to protect ourselves and the environment from the negative impacts of this phenomenon.
