Unprecedented Sahara Dust Cloud Engulfs Caribbean
A colossal cloud of dust originating from the Sahara Desert has enveloped much of the Caribbean, marking the largest event of its kind this year. Spanning approximately 2,000 miles from Jamaica to beyond Barbados in the eastern Caribbean, and stretching 750 miles from the Turks and Caicos Islands to Trinidad and Tobago, the plume has created hazy skies and triggered health concerns across the region. Reported on June 2, this massive dust event has left residents dealing with sneezes, coughs, and watery eyes, prompting local forecasters to advise those with allergies or asthma to stay indoors or wear masks when outside.
The scale of this dust cloud has been described as 'very impressive' by Alex DaSilva, lead hurricane expert with AccuWeather. The dust concentration reached an aerosol optical depth of 0.55, the highest recorded so far this year, according to Yidiana Zayas, a forecaster in the region. As the plume continues its journey across the Atlantic, it has already affected areas like Puerto Rico, Cuba, Haiti, and the Dominican Republic, with images showing a thick haze over cities and ports.
Impact and Forecast for the United States
The Sahara dust cloud is now on a northwest trajectory, expected to reach Florida by mid-week following June 2. Forecasts indicate that by Friday, the plume will impact several southeastern states including Georgia, the Carolinas, Texas, and Louisiana. A smaller dust plume had already arrived in Florida over the weekend prior to June 2, with radar showing lingering dust over the state on Monday, as reported by weather experts tracking the phenomenon.
This incoming dust is anticipated to degrade air quality in affected US regions, particularly in Florida, where a larger plume is set to arrive. Jason Dunion, a hurricane scientist at NOAA, noted that such events can influence local weather patterns and create vivid sunrises and sunsets due to the scattering of light by dust particles. Residents in the southeastern US are advised to monitor air quality alerts and take precautions if they have respiratory conditions.
Interestingly, the presence of Saharan dust can also play a role in suppressing tropical storm development by disrupting atmospheric conditions, a point highlighted in posts found on X discussing the phenomenon's broader meteorological impacts. As this natural event unfolds, both Caribbean and US communities brace for its effects on health and visibility.
