Believe it or not, not only do we have hot and sticky weather (high mold count) but our pollen collector has detected Saharan dust. We had some in the air last year at this time as well.
Because of intense heat and very dry air, the dust particles of the Sahara desert rise up 15,000 feet in the air, and the plume of dry, dusty air is carried by winds 5,000 miles across the Atlantic to the Caribbean and southern United States. It causes the sky to be hazy and can make for beautiful sunrises and sunsets. The health consequences are not well known, although I would guess that it is not healthy air to breathe, so asthmatics might limit their time outside and exposure to Saharan dust.
