The Met Service says a second plume of the Saharan dust is expected to hover over the island this weekend.
Duty Forecaster at the Met Service, Clayton Johnson, says the current plume is expected to dissipate by today.
He says sections of Eastern and Central parishes experienced rainfall and thunderstorm last evening.
But Mr Johnson says generally during the Sahara dust event, no rainfall is expected because the phenomenon prevents the development of rain clouds.
But Mr Johnson is warning people not to drop their guards noting we are currently in the hurricane season.
