Saharan dust plume reaches Cayman, raising air quality concerns
A large plume of Saharan dust moving across the Atlantic has reached the Caribbean and is beginning to affect air quality in the Cayman Islands, with forecasters warning that dust concentrations are expected to remain through the weekend and into early next week.
Air quality data from the United Nations Environment Programme’s IQAir platform showed levels of PM2.5 – tiny airborne particles commonly found in dust, smoke and pollution – rising on-island from 19 micrograms per cubic metre at 11am on 29 May to 25 micrograms per cubic metre by 1pm, five times higher than the World Health Organization’s guideline value.
