A mass of Saharan dust being transported by an Atlantic High Pressure circulation should blanket the island chain this week. Persons with respiratory conditions should be aware that dust concentrations could significantly increase by Monday afternoon and PM2.5 levels could peak near 22µg/m3 while PM10 levels peak near 39µg/m3 during Tuesday. Hazy conditions of varying intensity could reduce visibility and persist for a few days. Meanwhile, lower-level moisture associated with a weak tropical wave is expected to cross our area late Tuesday into Wednesday
