DALLAS — It is that time of the year when Saharan Dust from the Saharan desert in Africa makes its way across the pond.
As of Thursday morning, there was a noticeable haze in North Texas. Most models are indicating that is is just the beginning. A noticeable increase is expected Thursday afternoon through the end of the week. The southerly wind helps bring a blanket of dust along with the hot, muggy weather.
We generally see this dust make the 5,000-7000-mile trek across the Atlantic Ocean during the late spring, summer and early autumn.
Violent thunderstorms in the desert toss dust into the mid-levels of the atmosphere. This allows the Saharan dust to be carried by the easterly trade winds from the western African coastline all the way across the Atlantic. The very dry, dusty air traveling across the ocean is associated with a reduced level of tropical development. This dust is also crucial for the fertilization of the Amazon.
What does it mean for North Texas?
No, it will not look like a wall of dust or a haboob. It'll actually look more like a haze on the horizon.
When the plume comes in heavy, you'll actually see it on cars and other surfaces. More than likely you'll notice the hazy skies and the colorful sunrises and sunsets. Dust particles reflect and refract the sun's light as it is rising and setting giving us vibrant colors in the sky.
One of the more annoying parts is the decreased air quality it may cause. People with asthma or respiratory issues need to keep this is mind.
The added dust is an irritant and may cause itchy eyes and a sore throat. If you notice this kind of discomfort, it is best to limit time outside or simply wear a mask.
