The U.S. South – and into Arkansas and Texas – are experiencing very dusty sunsets and sunrises. They’re due to an unusually large plume of dust from northern Africa’s Saharan Desert, which wafted across the Atlantic beginning just after mid-June. The Washington Post’s Capital Weather Gang wrote on June 25, 2020:
An unusually thick, nearly 5,000-mile-long plume of dust that was whisked off the Sahara Desert by storm-related winds June 14 is moving ashore along the coast of the Gulf of Mexico from Texas to the Florida Panhandle. It is predicted to cause a deterioration in air quality and turn the sky a milky white, and its impacts won’t be limited to the coast …
Although plumes of Sahara Desert dust are routinely ejected from Africa’s west coast during June, the ongoing event is extraordinarily rare, scientists said. This event stands out in terms of the dust layer’s thickness, its low altitude and geographic reach, causing a dramatic deterioration in air quality in Puerto Rico, Barbados, Guadeloupe and numerous other locations where records are maintained.
