A plum of Saharan dust is making its way to North Texas and will make skies hazy.
We're saying hello to an old visitor. A plum of Saharan dust is expected to make its way into North Texas. This will make the skies hazy, especially during the morning and evening hours. More plumes of dust are coming off the western coast of Africa and headed toward the United States. This dust event is something that happens every year, usually around late June and early July.
Although there are no health hazards associated with the dust, the dust may be irritating for those with allergies or lung issues. Those with breathing issues are advised to stay indoors or limit outdoor exposure on days with higher dust concentrations.Second, Saharan dust is extremely dry air that has 50% less moisture than a typical tropical airmass. This extreme dry air can weaken a tropical system by promoting downdrafts around the storm.
And third, Saharan dust is a signal of strong jet stream winds. These winds can increase the vertical wind shear in and around the storm environment. This will cause a disruption in the development of a tropical system.Normally when the sun is lower in the sky, the light travels through more atmosphere. As this happens, it scatters the shorter wavelength colors such as blue, purple and green. This allows the longer wavelength colors such as orange, pink and red, to reach the human eye.
Add Saharan dust to the atmosphere and its tiny minerals not only act to block some sunlight, but they also reflect it and scatter the colors even more. The additional scattering will create more vivid hues of reds, oranges, pinks, yellows and even purples. Thus, nice sunrises and sunsets are visible across North Texas.
