A massive Saharan dust cloud, the largest of the year, blanketed the Caribbean on Monday, causing respiratory issues and reduced visibility. Extending thousands of miles, the dust plume impacted islands from Jamaica to Trinidad and Tobago. Forecasters warned vulnerable individuals to stay indoors or wear masks. The cloud, with an aerosol optical depth of .55, is expected to reach parts of the southeastern United States later this week, though its concentration is likely to decrease.
