A colossal cloud of Sahara dust is smothering the Caribbean en route to the US
- On Monday, a large plume of Saharan dust spread across much of the Caribbean region near San Juan, Puerto Rico, before moving toward the United States.
- The Saharan Air Layer, a dust plume originating over the Sahara Desert, travels westward over the Atlantic Ocean from April through October, with the greatest dust levels typically occurring in June and July.
- This dust cloud extended about 2,000 miles from Jamaica past Barbados and 750 miles from Turks and Caicos to Trinidad and Tobago, reaching heights between 5,000 and 20,000 feet.
- Forecasters reported that this year's largest dust event featured an aerosol optical depth measurement of 0.55, marking a record concentration to date, which led to health advisories and earned the nickname 'Godzilla dust cloud.'
- The dust plume is projected to move over parts of the Gulf Coast, including states such as Florida, Louisiana, Alabama, and Mississippi, toward the end of this week, which may inhibit the development of tropical waves during hurricane season and lead to hazy conditions that could affect breathing.
