Why is this haze good at keeping hurricanes at bay, but bad for your health?
As you noticed on Tuesday, our skies had a milky look to them. This is because sand from the Saharan desert has made it all the way into South Florida.
This happens when huge storms whip up the sand in the Sahara, sending it upwards into the upper levels of the atmosphere where it is pushed our way by strong upper level winds. This dust cloud can be detected on special satellite imagery. You can see the huge plume of orange and yellow coming off Africa and heading West.
This cloud of dust keeps the atmosphere across the Atlantic mostly dry not allowing any storms to form that could develop into hurricanes.
The dust is an irritant and can worsen the condition of people who suffer from respiratory issues. Try to remain indoors if you can, in air-conditioned dwellings.
