Miami, FL – A new surge of Saharan dust is moving across the tropical Atlantic toward South Florida, bringing hazy skies, reduced rain chances, and changes to the region’s typical summertime weather pattern.
According to the National Weather Service in Miami, Saharan dust is a common occurrence across South Florida between late June and mid-August as easterly winds carry dust from the Sahara Desert across the Atlantic Ocean.
Forecasters say the dust layer suppresses the vertical growth of clouds, which typically results in fewer afternoon showers and thunderstorms than would otherwise develop. While overall storm coverage is expected to decrease, the National Weather Service notes that atmospheric conditions can also support a greater threat of isolated severe thunderstorms when storms do form.
The latest dust thickness forecasts from NASA’s Global Modeling and Assimilation Office indicate the plume will continue moving westward across the Atlantic, with South Florida expected to remain under its influence into early August.
In addition to reducing rainfall, Saharan dust can create hazy skies, lower visibility at times, and contribute to poorer air quality, particularly for people with asthma, allergies, or other respiratory conditions. Residents who are sensitive to airborne particles may want to limit prolonged outdoor activity if haze becomes more noticeable.
Despite the reduced rain chances, South Florida’s summer heat and humidity will continue, and isolated thunderstorms remain possible each afternoon.
The National Weather Service encourages residents to stay informed by monitoring local forecasts, especially if outdoor plans depend on changing weather conditions later this week.
