The season's first Saharan dust will make a big return to the Southeast, including our area this weekend. "This is a pretty common phenomenon," WYFF News 4 Chief Meteorologist Chris Justus said. "It's something we track and happens this time of year."The Saharan Air Layer, according to the NOAA's Atlantic Oceanographic and Meteorological Laboratory, is a mass of very dry, dusty air that forms over the Sahara Desert during the late spring, summer and early fall. This layer can travel and impact locations thousands of miles away from its African origins, which is one reason why NOAA uses the lofty perspective of its satellites to track it.For the Upstate, it means, starting Sunday, you may notice the hazy skies with a different tint. It also means more vibrant sunsets and sunrises. These effects will linger over the Southeast into the early part of the week. If you suffer from respiratory problems, it is possible that some of that dust mixes down to the ground and you could have some issues later in the day. Justus said most of it stays up higher in the atmosphere, so you shouldn't have to worry about it too much. The good news: When there is a lot of Saharan dust in the Atlantic, it helps suppress tropical activity.
