Air quality and Saharan dust across the island
Several times a year, the Saharan Air Layer (a plume of dry, dusty air) crosses the Atlantic and settles over the Caribbean (locally, la calima). It mutes the sky to a milky haze, lifts particulate readings, and can irritate eyes and airways, but it also tends to suppress tropical storm development.
Air quality & dust via Open-Meteo / Copernicus CAMS, as of Nov 5, 12:02 AM AST. For official guidance see AirNow.gov.
