Did it look a little hazy to you this morning?
Some might think it was from the Fourth of July fireworks or the humidity, and while those can definitely be a contributor to the haze, there is an explanation…. and it relates to the tropics!
Saharan Dust that is slowing working into the atmosphere. This is a very dry air mass full of dust from Africa that has drifted across the Atlantic. Tropical systems love clean and moist air but when the Saharan Dust air particulates take over, it is harder for tropical systems to develop.
The National Hurricane Center (NHC) is not monitoring anything in the tropics and that can be attributed to the dust suffocating storm development and creating the haze in our skies.

The monsoonal pattern for Africa has been weak so more of the Saharan Desert Air has been able to move across the tropical waters of the Atlantic. With little storm development to help wash out the atmosphere, the dust has made its way to South Florida. The dust is also impacting the Greater Antilles, The Bahamas, and Hispaniola.
This weekend, the forecast calls for higher Saharan Dust particles and lower storm chances … meaning more hazing skies, and beautiful sunsets, as the dust helps beautify the evening light.
